CPT Code 97162: Documentation, Billing & Compliance Guide for Healthcare Providers [2026]

CPT code 97162 is the AMA-designated billing code for a moderate-complexity physical therapy evaluation, requiring documented assessment of three or more body systems, one to two comorbidities affecting the plan of care, and moderate-level clinical decision-making for an evolving clinical presentation.

But here’s what most coding guides miss: billing 97162 correctly isn’t just about knowing the definition. The rules shift depending on your practice setting.

A private PT clinic, a hospital outpatient department, a multi-discipline rehabilitation facility, and a skilled nursing facility each face different payer expectations, different modifier requirements, and different audit risk profiles for the same code.

This guide covers CPT code 97162 billing from every angle, for PT practices, orthopedic groups, multi-specialty clinics, and every practice type that bills physical therapy evaluations across 100+ specialties.

What Is CPT Code 97162?

Official 97162 CPT Code Description

CPT code 97162 is defined by the American Medical Association (AMA) as a physical therapy evaluation of moderate complexity. The code was introduced in January 2017 when the tiered evaluation system replaced the legacy single-code structure (97001). Under the current framework, 97162 sits between 97161 (low complexity) and 97163 (high complexity).

Before 2017, every physical therapy evaluation used one code regardless of how complex the patient’s situation was. That didn’t give payers or providers a way to distinguish a straightforward ankle sprain evaluation from a multi-system neurological assessment. The tiered system fixed that.

Here’s what the 97162 CPT code definition requires. Three pillars must all be met, and each one has a specific documentation threshold:

Evaluation Component	97162 Moderate Complexity Requirement
Patient History	1 to 2 personal factors and/or comorbidities that directly influence the plan of care
Examination	Assessment of 3 or more elements across body structures, functions, activity limitations, or participation restrictions
Clinical Presentation	Evolving condition with changing characteristics, requiring moderate clinical decision-making

That table isn’t a suggestion. It’s the billing criteria. Miss any one of those three, and 97162 isn’t the right code.

Critical Rule: The evaluation code is determined by the lowest qualifying pillar, not the highest. If your patient history and examination both support moderate complexity but the clinical presentation is stable and predictable, the correct code is 97161, regardless of how thorough the exam was. All three pillars must independently meet moderate-complexity criteria before 97162 can be billed.

This is where a lot of practices get tripped up. A therapist runs a comprehensive exam covering five body systems, documents two comorbidities, but the patient’s condition is completely stable. Nothing’s changing. The exam supports moderate. The history supports moderate. But the clinical presentation doesn’t. That’s a 97161.

The lowest pillar sets the ceiling. Not the highest.

This applies regardless of your practice type. Whether you’re a standalone PT clinic, an orthopedic group with in-house therapy, a hospital outpatient rehabilitation department, or a multi-discipline practice, the three-pillar complexity framework and the lowest-pillar rule are identical. What changes across settings is the documentation system, the payer expectations, and the audit risk profile, not the code definition itself.

Is CPT Code 97162 Timed or Untimed?

CPT code 97162 is an untimed, service-based code. It is billed once per evaluation session regardless of how long the evaluation takes, provided the documentation supports moderate complexity across all three pillars.

The typical benchmark is approximately 30 minutes of face-to-face patient contact. But billing is based on complexity, not on the clock. A 20-minute evaluation that clearly documents moderate complexity across all three pillars is billable as 97162. A 45-minute evaluation where the documentation only supports low complexity isn’t.

Here’s a distinction that trips up newer billers: the 8-minute rule doesn’t apply here. That rule governs timed therapeutic procedure codes like 97110 (therapeutic exercise) and 97140 (manual therapy). When a therapist performs both an evaluation and treatment on the same day, the evaluation time stays completely separate from the 8-minute calculation for treatment units. They’re different billing categories.

The Medically Unlikely Edit (MUE) for CPT 97162 limits billing to 1 unit per date of service per provider. Because it’s untimed, there’s no scenario where billing multiple units of 97162 on the same date is appropriate.

97162 Quick Reference:

Fact	Detail
Code Type	Untimed, service-based
Units Per DOS	1 (MUE limit)
8-Minute Rule	Does NOT apply
Typical Time	~30 minutes face-to-face
Billing Basis	Documented complexity, not time

Who Can Bill CPT Code 97162?

Only qualified licensed clinicians can perform and bill physical therapy evaluations. Physical therapist assistants (PTAs) and occupational therapy assistants (OTAs) can’t perform initial evaluations or re-evaluations under Medicare, Medicaid, or the vast majority of commercial payer contracts.

The rendering NPI on the claim must match the licensed physical therapist who personally conducted the evaluation. When a PTA’s NPI appears on a 97162 claim line, the result is an automatic denial. That’s a credentialing and enrollment issue that should be caught at the scheduling level, not after the claim is rejected.

In multi-specialty practices and hospital outpatient departments, this rule gets operationally more complex. When multiple provider types share scheduling systems, evaluation appointments must be routed exclusively to licensed PTs. Not PTAs, not students, and not providers from other disciplines who aren’t qualified to perform PT evaluations. The rendering NPI verification should happen at scheduling, not during claim review.

When Should You Use CPT Code 97162?

Clinical Criteria for Selecting CPT 97162

Selecting the right CPT code for a physical therapy evaluation and treatment session comes down to three documented criteria. Use CPT code 97162 only when all three are met simultaneously.

1. History: 1 to 2 Comorbidities or Personal Factors

The patient presents with at least one condition or personal circumstance that complicates the plan of care. Diabetes affecting tissue healing. Obesity limiting exercise tolerance. Cardiac history requiring modified exercise parameters. Occupational demands that influence goal-setting. Mental health conditions affecting compliance.

These factors don’t need to be the primary diagnosis. They just need to demonstrably influence how the treatment plan is designed. A patient with knee pain and well-controlled hypertension that doesn’t change your treatment approach? That’s not a qualifying comorbidity for 97162.

2. Examination: 3 or More Elements Assessed

The evaluation must cover at least three distinct assessment areas across body structures, functions, activity limitations, or participation restrictions. Strength plus range of motion plus balance plus gait analysis gets you there.

Only two elements documented? That’s 97161 territory.

Each element requires objective, measurable findings. “ROM assessed” doesn’t satisfy the requirement. “Right shoulder flexion 95°/180°” does. The difference between those two documentation styles is often the difference between a clean payment and a downcoded claim.

3. Clinical Presentation: Evolving with Changing Characteristics

An evolving clinical presentation means the patient’s condition is actively changing rather than remaining stable. Pain levels fluctuate between visits. New functional limitations emerge. Weight-bearing tolerance shifts as recovery progresses.

The condition requires moderate-level clinical reasoning when building the plan of care. If the presentation is stable and predictable, the correct code is 97161. “Evolving” isn’t a judgment call you make after the fact. It’s a clinical reality you document during the evaluation.

The decision rule is straightforward: if any single pillar falls below moderate complexity, the evaluation must be downcoded to 97161. If all three pillars point to high complexity, meaning three or more comorbidities, four or more examination elements, and an unstable or unpredictable presentation, bill CPT code 97162’s higher-tier counterpart, 97163, instead.

Clinical Scenarios Across Practice Settings

Real-world examples make this easier to apply. Each scenario below walks through the three-pillar analysis for a 97162 CPT code physical therapy evaluation in a different practice setting.

Scenario 1, Sports Medicine: ACL Reconstruction Patient with Asthma

A 24-year-old collegiate athlete presents eight weeks post-ACL reconstruction. She has exercise-induced asthma that requires monitoring during high-intensity rehab activities and alters the progression timeline.

The PT evaluates knee ROM, lower extremity strength, single-leg balance, and functional hop testing. Pain and functional capacity change weekly as the graft matures.

Two personal factors (surgical history + asthma), four exam elements, evolving recovery. → Bill 97162.

Scenario 2, Outpatient Orthopedic: Lumbar Fusion Patient with Depression

A 55-year-old office manager presents 12 weeks post-L4-L5 lumbar fusion with comorbid clinical depression affecting pain perception and exercise motivation. Assessment covers lumbar ROM, core stability, gait mechanics, and functional lifting capacity.

Neurological symptoms and movement patterns are actively evolving as surgical fusion consolidates.

Two comorbidities (post-surgical status + depression), four exam elements, evolving presentation. → Bill 97162.

Scenario 3, Hospital Outpatient Rehab: Hip Fracture Patient with COPD

A 78-year-old following ORIF for a right hip fracture, with COPD limiting exercise tolerance and requiring oxygen monitoring during mobility training. The PT evaluates hip ROM, lower extremity strength, static and dynamic balance, and transfer independence.

Recovery trajectory is changing as the patient transitions from acute post-surgical to community mobility goals.

Two comorbidities (post-surgical hip fracture + COPD), four exam elements, evolving recovery. → Bill 97162.

In all three scenarios, regardless of practice setting, the documentation must connect the comorbidities to the treatment approach and explain why the clinical presentation is evolving. Without that explicit connection, payers can and will argue the evaluation was low complexity.

The comorbidity has to matter to your clinical decisions. Simply listing it in the history isn’t enough.

CPT 97161 vs 97162 vs 97163: How to Select the Correct Evaluation Complexity Level

Picking the wrong evaluation code is one of the most expensive mistakes a PT practice can make. Not because any single claim breaks the bank, but because the error repeats on every evaluation, every day, every week.

Here’s a side-by-side breakdown of what separates the three complexity levels.

Side-by-Side Comparison Table

Criteria	CPT 97161 (Low)	CPT 97162 (Moderate)	CPT 97163 (High)
Personal Factors / Comorbidities	0	1–2	3+
Body Systems Examined	1–2 elements	3+ elements	4+ elements
Clinical Presentation	Stable, predictable	Evolving, changing	Unstable, unpredictable
Decision-Making Complexity	Low	Moderate	High
Typical Face-to-Face Time	~20 minutes	~30 minutes	~45 minutes
2026 Medicare National Rate	~$93	~$101.20	~$114
Code Type	Untimed / Service-Based	Untimed / Service-Based	Untimed / Service-Based
MUE (Units Per DOS)	1	1	1

(Verify exact 2026 rates for 97161 and 97163 from the CMS PFS Look-Up Tool before publishing.)

The CPT code 97161 description covers the simplest evaluations: stable condition, no significant comorbidities, one to two assessment elements, straightforward clinical reasoning. An isolated ankle sprain in an otherwise healthy 25-year-old fits here.

The 97163 CPT code description sits at the opposite end. Unstable or unpredictable presentation, three or more comorbidities, four or more examination elements. Think post-stroke patients with cardiac history, cognitive deficits, and complex medication regimens.

So what’s the real difference between 97161 and 97162? It’s not time.

A 35-minute evaluation on a stable patient with a single straightforward complaint is still 97161. What moves you to the 97162 CPT code is clinical reasoning documented across all three pillars, not minutes on the clock. The PT evaluation CPT code level is set by complexity, and complexity is set by your documentation.

The Compliance Risk of Systematic Miscoding

Code selection errors aren’t just a revenue problem. They’re a compliance risk that scales with your practice size.

Overcoding means billing 97162 when the documentation only supports 97161. Do this consistently and Medicare contractors notice. They use data analytics to identify providers whose 97162-to-97161 ratio significantly exceeds regional averages. Practices flagged for high-complexity billing patterns face Targeted Probe and Educate (TPE) reviews. Once that happens, the documentation burden shifts to your team to justify every evaluation code selected during the audit period.

Undercoding means billing 97161 when the documentation clearly supports 97162. It won’t trigger an audit, but it’s a financial leak. A practice seeing 15 evaluations per week that routinely undercodes loses $6,200 to $16,300 annually from a single code selection error. No new patients needed. No new contracts. Just billing what you’ve already earned at the correct complexity level.

Both directions come down to the same root cause: code selection that doesn’t match what’s documented.

Not sure whether your evaluations are coded at the right complexity level? That uncertainty costs money in both directions, and practices with consistently skewed coding ratios face increased audit scrutiny. Claimmax RCM’s certified coding specialists review every claim across 100+ specialties to match documented complexity to the correct code. At just 2.95% of collections, the lowest rate in the industry, with no setup fees and no long-term contracts, accurate code selection costs less than a single denied claim.

Documentation Requirements for CPT Code 97162

A perfectly coded 97162 claim means nothing if the evaluation note can’t back it up. Payer auditors don’t care what code you selected. They care whether the documentation independently supports moderate complexity across all three pillars.

What Payer Auditors Check in a 97162 Evaluation Note

Medicare contractors and commercial payers audit CPT code 97162 claims by looking for explicit evidence. Vague notes, template-driven records, and missing objective data are the primary reasons evaluations get downcoded or denied outright.

Here’s what auditors need to find in your documentation.

1. Patient History Must Document:

At least one to two specifically named comorbidities or personal factors.

✅ Passes audit: “Patient has Type 2 diabetes (A1C 7.8) and BMI of 31. Both conditions affect exercise tolerance and wound healing, requiring modified intensity parameters.”

❌ Fails audit: “Patient has multiple medical issues.”

The note also needs prior level of function compared to current limitations, plus relevant surgical, injury, or treatment history.

2. Examination Must Document:

Assessment of three or more distinct elements with objective, measurable findings.

✅ Passes audit: “Right shoulder flexion 95°/180°” … “R quad 3+/5” … “Berg Balance Scale 38/56”

❌ Fails audit: “ROM tested. Strength tested. Balance assessed.”

Each element requires actual measured values. Writing “tested” or “assessed” without numbers doesn’t satisfy the requirement.

3. Clinical Decision-Making Must Document:

A clear explanation of why the presentation is evolving.

✅ Passes audit: “Pain fluctuating from 4/10 to 8/10 over the past week with new onset of nighttime discomfort and decreased tolerance to previously tolerated activities.”

❌ Fails audit: “Patient’s condition is changing.”

The note must also show how comorbidities directly influence the treatment approach, along with specific, measurable goals tied to findings. Something like “Improve TUG from 18s to 12s within 6 weeks” works. “Improve function” doesn’t.

4. Medical Necessity Statement Must Include:

Why physical therapy is necessary for this specific patient, with a direct connection between evaluation findings and functional deficits that PT can address.

The Documentation Format That Survives Audits

Use a SOAP note format or the evaluation-specific format recommended by APTA. The format itself matters less than the content inside it.

Here’s a practical test: if an auditor can’t locate the comorbidities, the three or more exam elements with objective measurements, and the clinical rationale for “evolving presentation” within 60 seconds of reading the note, the documentation needs work.

Audit Red Flag: Cloned evaluation notes, where every patient’s documentation uses identical phrasing with only the name and date changed, are the fastest trigger for a targeted medical review. Medicare contractors use text-matching algorithms to flag template language across patient records. Every 97162 CPT code evaluation note must reflect the individual patient’s unique clinical picture.

Templates are fine as starting frameworks. But every measurable value, every comorbidity reference, and every clinical rationale statement must be specific to the patient sitting in front of the therapist.

Which Modifiers Apply to CPT Code 97162?

Complete Modifier Reference for 97162

Applying the wrong modifier to a 97162 CPT code claim, or forgetting one entirely, is one of the most preventable reasons physical therapy claims get denied. The modifier tells the payer critical context about the service: who performed it, whether it’s part of a therapy plan, and whether related services on the same date are distinct.

Here’s every CPT 97162 modifier you need to know, when it applies, and whether it’s required or situational.

Modifier	Name	When to Use with 97162	Required?
GP	Physical Therapy Plan of Care	Every Medicare PT claim line. Indicates service falls under an outpatient PT plan.	✅ Medicare required
KX	Therapy Threshold Certification	When cumulative annual therapy spend exceeds the $2,480 KX threshold (2026, PT + SLP combined). Certifies continued medical necessity.	✅ When threshold exceeded
CQ	Service Furnished by PTA	On PTA-furnished treatment lines only, not on 97162 itself. PTAs can’t perform evaluations. Triggers a 15% payment reduction.	✅ On PTA treatment lines
CO	Outpatient Hospital Setting	Identifies services performed in a hospital outpatient department. Required by some MACs when billing the professional component in hospital OPD settings.	✅ Hospital OPD (payer-dependent)
59	Distinct Procedural Service	When billing 97162 alongside an NCCI-flagged code like 97140. Bypasses the bundling denial.	✅ When NCCI edit applies
XE	Separate Encounter	CMS-preferred alternative to Modifier 59. Indicates services occurred during a separate encounter on the same date.	✅ Preferred over 59 by CMS
XS	Separate Structure	Evaluation and treatment target anatomically distinct body structures.	Situational
XP	Separate Practitioner	A different qualified clinician performed the distinct service.	Situational
25	Significant, Separately Identifiable E/M	A separately billable E/M service was performed the same day as the PT evaluation.	Situational
GY	Statutorily Non-Covered	Service isn’t a covered benefit. Submitted for ABN tracking and denial documentation purposes.	Rare
GN	Speech-Language Pathology	❌ Do NOT use with 97162. GN is for SLP services. PT services require GP.	❌ Not applicable

That’s 11 modifiers your team needs to understand for 97162 physical therapy billing. Miss the right one, and the claim either denies outright or pays incorrectly.

The CO Modifier for Hospital Outpatient Departments

This one deserves special attention. The CO modifier identifies services furnished in a hospital outpatient department. It’s not universally required for 97162, but certain Medicare Administrative Contractors require CO when the professional component of a PT evaluation gets billed from a hospital-based outpatient setting. Practices operating within hospital systems should verify their MAC’s specific modifier requirements.

Here’s the thing: standalone PT clinics never encounter this modifier. But hospital-based therapy programs miss it regularly because most coding guides are written exclusively for private practice audiences. If your practice operates under a hospital system, check with your MAC before assuming CO doesn’t apply to you.

Modifier 59 vs. XE: Which One Do You Use?

CMS has stated the X-modifier series (XE, XP, XS, XU) should replace Modifier 59 whenever possible for greater specificity. In practice, adoption varies widely by payer.

Some commercial carriers still process Modifier 59 without issue. Others reject 59 and require XE instead. A few don’t recognize X-modifiers at all. Verify each payer’s modifier preference during benefit verification. Adding this single field to your intake checklist takes seconds and prevents days of rework on denied 97162 claims.

The KX Modifier Threshold in 2026

The 2026 KX modifier threshold is $2,480 for combined physical therapy and speech-language pathology services under Medicare. Once a patient’s cumulative charges exceed that amount in a calendar year, KX must be appended to every subsequent service line. That includes evaluations billed under CPT code 97162.

Missing KX above the threshold results in automatic denial. No human reviews it. There’s no appeal opportunity until you resubmit with the modifier attached. It’s a completely avoidable denial that happens because someone wasn’t tracking cumulative charges.

The Targeted Medical Review threshold remains at $3,000 for 2026. As charges approach that level, treat every claim as audit-ready. Documentation quality matters more above this line, not less

Modifier errors are the easiest denial category to eliminate, and the most expensive to ignore. Claimmax RCM tracks KX thresholds in real time, verifies payer-specific modifier preferences before submission, and applies the correct modifier on every claim line, whether your practice is a standalone PT clinic, a hospital outpatient department, or a multi-discipline rehabilitation facility. At 2.95% of collections with no hidden fees, it costs less than the staff time you spend on modifier-related rework. See how our billing works →

Can You Bill 97162 with Other CPT Codes? NCCI Bundling Rules Explained

Bundling errors create some of the most frustrating denials in physical therapy billing. The claim looks clean, the documentation supports the service, and the modifier is correct, but CMS still denies the line because two codes can’t live on the same claim without specific conditions being met.

Here’s how the NCCI rules work for every common 97162 CPT code pairing.

97162 and 97140: Billing Together

An NCCI Procedure-to-Procedure (PTP) edit exists between CPT 97162 and CPT 97140 (manual therapy). Submit both on the same date without a modifier and CMS denies the 97140 line automatically. No review. No exception.

The fix: append Modifier 59 or the appropriate X-modifier (XE, XS, XP, or XU) to CPT 97140, not to 97162. The modifier goes on the treatment code. Your documentation must support that the manual therapy was clinically distinct from the evaluation. APTA’s NCCI guidance (January 2020) confirms this requirement.

What usually happens in practice: billers append the modifier to the wrong line. It goes on 97162 instead of 97140, and CMS denies it anyway. Small detail. Big consequence.

97162 and 97110: Billing Together

Can 97162 and 97110 be billed together? Generally, yes. These codes aren’t currently paired in the NCCI PTP edit tables. Billing both on the same date doesn’t typically trigger an automatic denial.

One caveat worth noting: CMS updates NCCI edit tables quarterly. The Q1 2026 update was released December 1, 2025. Check the current file at least every 90 days. A pairing that’s clean today could show up as an edit next quarter.

97162 and 97530: Critical Clarification

This is where practices get burned. NCCI edits DO exist between CPT 97530 (therapeutic activities) and the PT evaluation codes (97161, 97162, 97163). Unlike the 97140 edit, this one can’t be bypassed with Modifier 59 or X-modifiers.

Per APTA’s January 2020 NCCI guidance: when 97530 and a PT evaluation code are billed together on the same day for the same patient, the evaluation code takes priority and the 97530 line is denied. The 59 modifier and X-modifier series don’t override this edit.

Many practices assume 97530 works like 97140, where a modifier solves the problem. It doesn’t. Schedule therapeutic activities for a separate date of service when clinically appropriate. That’s the only clean path.

Codes Inclusive Within the Evaluation

CMS Medicare guidance, including Noridian LCD articles, states that formal assessment codes like CPT 97750 (physical performance testing) and certain manual muscle testing codes are considered inclusive within the initial evaluation. They aren’t separately reimbursable on the same date as CPT 97162.

If your therapist performed standardized testing during the evaluation, that work is part of the evaluation service, not a separate billable line.

Quick-Reference Bundling Table

Code Combination	NCCI Edit?	Modifier Bypass?	Action
97162 + 97140	✅ Yes	Mod 59 or X-modifier on 97140	Bill with modifier; document distinct services
97162 + 97110	❌ No (verify quarterly)	Not typically required	Bill normally
97162 + 97530	✅ Yes	❌ Cannot bypass with modifier	Do NOT bill together; schedule separately
97162 + 97750	✅ Inclusive	N/A, not separately billable	Do NOT bill separately on eval date
97162 + 97161/97163	✅ Mutually exclusive	N/A	Only ONE eval code per discipline per DOS
97162 + 97164	✅ Mutually exclusive	N/A	Only ONE eval or re-eval per discipline per DOS
97162 + 97166 (OT eval)	❌ No, different discipline	N/A	Both billable if separate disciplines, separate providers, separate documentation

That last row matters if you run a multi-discipline practice. A PT evaluation (97162) and an OT evaluation (97166) for the same patient on the same day are both billable. Different disciplines, different providers, different documentation. No NCCI conflict. But both notes need to stand on their own, with independent clinical rationale for each evaluation.

This is a pairing most coding guides don’t cover because they’re written for single-discipline PT clinics. If your practice has PT, OT, and SLP under one roof, knowing which cross-discipline combinations are clean saves you from leaving legitimate revenue on the table.

Bookmark the CMS NCCI PTP edit tables and check them quarterly. The rules don’t stay static, and finding out about a new edit from a denial is the expensive way to learn.

Can You Bill 97162 with Other CPT Codes? NCCI Bundling Rules Explained

Bundling errors create some of the most frustrating denials in physical therapy billing. The claim looks clean. Documentation supports the service. Modifiers are correct. But CMS still denies the line because two codes can’t coexist on the same claim without specific conditions being met.

Here’s how the NCCI rules work for every common 97162 CPT code pairing.

97162 and 97140: Billing Together

An NCCI Procedure-to-Procedure (PTP) edit exists between CPT 97162 and CPT 97140 (manual therapy). Submit both on the same date without a modifier, and CMS denies the 97140 line automatically. No review. No exception.

The fix: append Modifier 59 or the appropriate X-modifier (XE, XS, XP, or XU) to CPT 97140, not to 97162. The modifier always goes on the treatment code. Your documentation must support that the manual therapy was clinically distinct from the evaluation. APTA’s NCCI guidance (January 2020) confirms this requirement.

What usually happens in practice: the biller appends the modifier to 97162 instead of 97140. CMS denies it anyway. Small detail, but it’s the difference between a clean payment and a rework cycle.

97162 and 97110: Billing Together

Can 97162 and 97110 be billed together? Generally, yes. These codes aren’t currently paired in the NCCI PTP edit tables. Billing both on the same date doesn’t typically trigger an automatic denial.

One caveat: CMS updates NCCI edit tables quarterly. The Q1 2026 update was released December 1, 2025. Check the current file at least every 90 days. A pairing that’s clean today could show up as an edit next quarter, and finding out from a denial is the expensive way to learn.

97162 and 97530: Critical Clarification

This is where practices get burned. NCCI edits DO exist between CPT 97530 (therapeutic activities) and the PT evaluation codes (97161, 97162, 97163). Unlike the 97140 edit, this one can’t be bypassed with Modifier 59 or X-modifiers.

Per APTA’s January 2020 NCCI guidance: when 97530 and a PT evaluation code are billed together on the same day for the same patient, the evaluation code takes priority and the 97530 line is denied. The 59 modifier and X-modifier series don’t override this edit.

Many practices assume 97530 works like 97140, where a modifier solves the problem. It doesn’t. Schedule therapeutic activities for a separate date of service when clinically appropriate. That’s the only clean path forward.

Codes Inclusive Within the Evaluation

CMS Medicare guidance, including Noridian LCD articles, states that formal assessment codes like CPT 97750 (physical performance testing) and certain manual muscle testing codes are considered inclusive within the initial evaluation. CPT 97162 can’t be billed separately alongside these codes on the same date.

If your therapist performed standardized testing during the evaluation, that work is part of the evaluation service. It’s not a separate billable line.

Quick-Reference Bundling Table

Code Combination	NCCI Edit?	Modifier Bypass?	Action
97162 + 97140	✅ Yes	Mod 59 or X-modifier on 97140	Bill with modifier; document distinct services
97162 + 97110	❌ No (verify quarterly)	Not typically required	Bill normally
97162 + 97530	✅ Yes	❌ Cannot bypass with modifier	Do NOT bill together; schedule separately
97162 + 97750	✅ Inclusive	N/A, not separately billable	Do NOT bill separately on eval date
97162 + 97161/97163	✅ Mutually exclusive	N/A	Only ONE eval code per discipline per DOS
97162 + 97164	✅ Mutually exclusive	N/A	Only ONE eval or re-eval per discipline per DOS
97162 + 97166 (OT eval)	❌ No, different discipline	N/A	Both billable with separate disciplines, providers, and documentation

That last row matters for multi-discipline practices. A PT evaluation (97162) and an OT evaluation (97166) for the same patient on the same day are both billable. Different disciplines, different providers, different documentation. No NCCI conflict exists between them.

Both notes need to stand independently, though. Each evaluation requires its own clinical rationale, its own objective findings, and its own treatment plan. Cross-referencing between disciplines for clinical continuity is fine, but the billing documentation for each must hold up on its own.

How CPT Code 97162 Billing Differs Across Practice Settings

Most 97162 coding guides are written for one setting: the standalone PT clinic. That works if your practice fits that mold. But if you’re billing from a hospital outpatient department, a skilled nursing facility, a home health agency, or a multi-discipline rehabilitation center, the rules aren’t identical.

The code definition stays the same everywhere. What changes is how claims get submitted, which modifiers apply, and how reimbursement gets calculated. Here’s what each setting needs to know.

Private Practice PT Clinics

In standalone PT practices, 97162 billing is the most straightforward version. The practice bills under the therapist’s NPI, appends Modifier GP for Medicare, and follows standard NCCI bundling rules.

The primary risk here isn’t complexity. It’s documentation quality. Smaller practices often lack internal coding review processes. Nobody’s auditing the notes before claims go out, which means documentation gaps don’t surface until claims deny. By then, you’re chasing corrections instead of preventing them.

Hospital Outpatient Departments (HOPD)

Hospital-based outpatient therapy programs face a split-billing model. The PT evaluation generates both a professional claim for the therapist’s service and a facility claim for the hospital’s overhead and infrastructure. The 97162 CPT code appears on both claims, but modifier requirements can differ between them.

Some MACs require Modifier CO on the professional component to identify the hospital outpatient setting. The facility claim follows APC (Ambulatory Payment Classification) reimbursement rules rather than the Physician Fee Schedule. That means the hospital’s payment for the same 97162 evaluation gets calculated differently than a private practice’s payment for the exact same service.

Hospitals also need to comply with CMS’s Provider-Based Department (PBD) rules. These affect where services can be furnished and how they’re billed. Therapy departments operating under provider-based status carry different compliance obligations than freestanding clinics.

Skilled Nursing Facilities (SNF)

PT evaluations in SNFs follow a different reimbursement pathway entirely. Under the Patient-Driven Payment Model (PDPM), PT services contribute to the therapy component of the SNF’s per diem rate rather than getting billed separately under Part B.

Here’s where it gets nuanced: when a SNF resident receives outpatient therapy services under Part B instead of Part A, standard CPT code 97162 billing rules apply. That includes the GP modifier, KX threshold tracking, and full NCCI bundling compliance. The billing path depends on which Medicare benefit the patient is using, not just where they’re physically located.

Home Health Settings

PT evaluations performed under a home health plan of care are typically bundled into the Home Health Resource Group (HHRG) payment under the Patient-Driven Groupings Model (PDGM). The 97162 code may still appear in clinical documentation, but it isn’t separately billed when services fall under the home health benefit.

The exception: when a home health patient receives outpatient PT services outside the home health episode, say at a freestanding clinic, standard Part B 97162 billing rules apply. The key question is always whether the service falls inside or outside the active home health episode.

Multi-Discipline Rehabilitation Facilities

Practices offering PT, OT, and SLP under one roof face the most complex billing landscape for evaluation codes. Each discipline bills its own evaluation independently. A PT evaluation (97162) and an OT evaluation (97166) for the same patient on the same day are two separate billable services, as long as the documentation and provider credentials support both.

The operational requirement is straightforward but strict: separate documentation, separate providers, separate clinical rationale. Cross-referencing notes between disciplines for clinical continuity is acceptable. But each evaluation has to stand on its own for billing purposes. An auditor reviewing the PT note shouldn’t need the OT note to understand why the PT evaluation was medically necessary.

Billing rules that work in a private PT clinic don’t always translate to a hospital outpatient department or a multi-discipline rehabilitation facility. Claimmax RCM works with practices across 100+ specialties and every practice setting, from standalone therapy clinics to hospital-based programs to multi-discipline rehab centers.

Multi-Discipline Same-Day Billing: When PT, OT, and SLP Evaluations Overlap

If your practice offers PT, OT, and SLP under one roof, same-day evaluation billing gets complicated fast. Most 97162 CPT code guides skip this topic entirely because they’re written for single-discipline clinics. But multi-discipline practices need clear rules for billing multiple evaluations on the same date of service.

Here’s how it works.

Billing PT and OT Evaluations on the Same Day

When a patient receives both a physical therapy evaluation (CPT code 97162) and an occupational therapy evaluation (97166) on the same date of service, both are separately billable. Three conditions must be met:

1. Separate qualified providers. A licensed PT performs and documents the PT evaluation. A licensed OT performs and documents the OT evaluation. The rendering NPIs on each claim line must reflect two different clinicians from two different disciplines. One provider can’t perform both.

2. Separate clinical documentation. Each evaluation must stand on its own. The PT note needs to support moderate complexity under PT criteria. The OT note needs to support the appropriate complexity level under OT criteria. Cross-referencing between notes for clinical continuity is acceptable, but each evaluation’s documentation must be clinically distinct and independently defensible.

3. Separate medical necessity. Each evaluation must address different functional deficits or different aspects of the patient’s condition. A PT evaluation focused on gait and lower extremity function paired with an OT evaluation focused on upper extremity fine motor skills and ADL performance represents distinct medical necessity for each discipline.

Miss any one of these three conditions, and one of the evaluations gets denied.

When PT, OT, and SLP Evaluations All Occur on the Same Date

In acute rehabilitation, post-stroke recovery, and traumatic brain injury cases, a patient may receive PT (97162), OT (97166), and SLP (92523) evaluations on the same day. All three are billable if those same three conditions are satisfied for each pair of disciplines.

The billing complexity increases with each discipline added. Each claim line needs the correct discipline-specific modifier. Mixing these modifiers across disciplines is one of the most common multi-discipline billing errors, and it triggers immediate denials.

Discipline	Evaluation Code	Required Modifier	Common Error
Physical Therapy	97162	GP	Using GN or GO on PT lines
Occupational Therapy	97166	GO	Using GP or GN on OT lines
Speech-Language Pathology	92523	GN	Using GP or GO on SLP lines

Each modifier tells the payer which discipline’s plan of care the service falls under. Get this wrong and the claim denies. Get it right across all three disciplines on the same date, with distinct documentation for each, and you’ve captured the full reimbursement for a complex multi-discipline evaluation day.

The KX Threshold Complication in Multi-Discipline Settings

Here’s where multi-discipline billing gets tricky in a way most practices don’t expect. The $2,480 KX threshold for 2026 applies to combined PT and SLP services. OT has its own separate $2,480 threshold.

In a multi-discipline practice where a patient receives both PT and SLP, their combined charges count toward a single $2,480 cap. But OT charges accumulate on a completely separate track.

Practices that track thresholds by individual discipline rather than by the combined PT plus SLP category miss the KX trigger point. The resulting denials don’t always make it obvious that a cross-discipline threshold calculation was the root cause. Your team sees a KX denial on a PT claim and can’t figure out why, because the PT charges alone haven’t hit $2,480. But add the SLP charges in, and you’re already past it.

Build your threshold tracking to combine PT and SLP from day one. It saves your team from chasing a denial that never should have happened.

CPT Code 97162 Reimbursement: Medicare Rates, RVUs and Payer Data [2026]

Knowing the code is only half the equation. Knowing what you’ll actually collect for a 97162 CPT code evaluation, and from which payers, determines whether your evaluation volume is financially sustainable.

Here’s the full 2026 reimbursement picture.

2026 Medicare National Payment Rate

Under the 2026 Medicare Physician Fee Schedule (PFS), CPT code 97162 has a national non-facility payment of approximately $101.20. This rate is calculated by multiplying the code’s total Relative Value Units (RVUs) by the 2026 conversion factor.

RVU Component	2026 Value
Work RVU	~1.20
Practice Expense RVU (Non-Facility)	~1.58
Malpractice RVU	~0.25
Total RVUs	~3.03
2026 Conversion Factor (Non-QP)	$33.4009
2026 Conversion Factor (QP/APM)	$33.5675
National Payment (Non-QP)	~$101.20
National Payment (QP)	~$101.71

Rates verified from CMS 2026 Physician Fee Schedule final rule.

The conversion factor increased to $33.40 from $32.35 in 2025, a nominal 3.26% bump. But CMS simultaneously applied a permanent 2.5% efficiency adjustment to work RVUs for untimed codes, which includes 97162. Net result: most practices see 97162 reimbursement stay flat or decline approximately 1% compared to 2025. The raise on paper doesn’t show up in your deposits.

State-Level Medicare Rate Variance

Medicare doesn’t pay one national rate. The Geographic Practice Cost Index (GPCI) adjusts payments by location, and the gap between states is significant.

State / Region	Estimated Medicare Part B Rate for 97162
Alabama	~$124
California	~$106
Florida	~$169
New Jersey	~$220
National Average	~$101.20

The spread between the lowest-paying and highest-paying states for 97162 exceeds $125 per evaluation. Where your practice sits geographically changes the math on every evaluation you perform.

Disclaimer: Reimbursement rates are estimates based on publicly available data and industry-reported figures. Actual reimbursement varies by geographic location, contracted rates, network status, and plan design. Always verify contracted rates with each payer. Medicare rates should be confirmed through the CMS PFS Look-Up Tool.

What This Means for Multi-Specialty Practices

Look at that table again. The gap between the lowest ($35 from Devoted Health) and highest ($320 from HN1 Therapy Network) payer rate for the same CPT code is $285. Your practice’s payer mix determines whether 97162 evaluations are profitable or barely cover overhead.

For multi-specialty practices billing across multiple disciplines, this variance compounds. A hospital outpatient department with a heavy Medicare Advantage population collecting $42 per evaluation operates under fundamentally different financial constraints than a private orthopedic group whose commercial contracts average $120. The code is the same. Documentation requirements are the same. The revenue is not.

That’s why payer mix analysis and contract benchmarking aren’t optional operational exercises. They’re essential to knowing whether your evaluation volume is financially sustainable across every specialty your practice serves. If you don’t know your blended rate per evaluation, you can’t make informed decisions about staffing, scheduling, or contract renegotiation.

Is your practice collecting the full reimbursement in this table, or leaving money behind on every evaluation? Across 100+ specialties and every practice setting, undercoded evaluations, missing modifiers, and below-market contracted rates compound fast.

What Changed for CPT Code 97162 in 2026? Key Medicare and Policy Updates

Every January brings a new round of CMS updates, and 2026 is no exception. For practices billing 97162 CPT code evaluations, the changes this year are subtle but financially meaningful. Here’s what shifted, what stayed the same, and what your team needs to act on.

The 2026 Conversion Factor: Why the “Raise” Doesn’t Increase Revenue

CMS increased the 2026 conversion factor to $33.4009 for most clinicians, up from $32.35 in 2025. For practices in qualifying Alternative Payment Models, the rate is $33.5675. On paper, that’s a 3.26% increase.

Here’s why your deposits won’t reflect it: CMS simultaneously applied a permanent 2.5% efficiency adjustment to work RVUs for nearly all untimed codes. CPT code 97162 is untimed. The RVU value driving payment dropped while the multiplier went up. They largely cancel each other out.

Metric	2026 Value	Impact on 97162
Conversion Factor (Non-QP)	$33.4009	+3.26% vs 2025
Conversion Factor (QP/APM)	$33.5675	+3.78% vs 2025
Work RVU Efficiency Adjustment	-2.5%	Partially offsets CF increase
KX Threshold (PT + SLP)	$2,480	Mandatory KX above this
Targeted Medical Review	$3,000	Increased audit probability
PTA General Supervision	Permanent	Operational scheduling gain
Net Reimbursement Change	~Flat to -1%	Revenue neutral at best

The bottom line: don’t budget for a raise on 97162 billing in 2026. Plan for flat reimbursement at best.

Telehealth Status for PT Evaluations After January 2026

Medicare telehealth flexibilities for physical therapists were extended through January 30, 2026, under H.R. 5371. As of February 2026, those flexibilities have expired unless Congress passed additional legislation after that date.

Action Required: If your practice bills PT evaluations via telehealth for Medicare patients, confirm current eligibility with your Medicare Administrative Contractor (MAC) for dates of service after January 30, 2026. Billing 97162 via telehealth without confirmed coverage results in automatic “provider not eligible” denials. Don’t assume last year’s rules still apply.

NCCI Edits and MUE Updates for Q1 2026

CMS released Q1 2026 NCCI Procedure-to-Procedure edits effective January 1, 2026, posted December 1, 2025. Medically Unlikely Edits were updated in the same release.

The CPT 97162 frequency limit, set by the MUE, typically restricts billing to one unit per date of service per provider. Verify the current quarter’s MUE through your MAC. CMS updates these tables quarterly, and the only way to stay current is to check each new release.

PTA General Supervision: A Scheduling Opportunity

General supervision for Physical Therapist Assistants in private practice under Medicare Part B is now permanent. The supervising PT no longer needs to be physically present while the PTA treats. Phone availability is sufficient.

The practical impact matters for your daily schedule. PTs can dedicate more of their day to initial evaluations billed under CPT code 97162, which reimburse at higher rates than most timed treatment codes, while PTAs manage the treatment caseload under general supervision. It’s a scheduling optimization that directly affects revenue per provider hour.

2026 CPT Code Set: No Changes to PT Evaluation Codes

The 2026 CPT code set released by the AMA included 418 total changes: 288 new codes, 46 revised, and 84 deleted. None of these changes affect CPT codes 97161, 97162, or 97163. The PT evaluation code descriptions, complexity criteria, and tiered structure remain unchanged.

If someone tells you “97162 changed for 2026,” it didn’t. The code definition is the same. What changed is the math behind how much you get paid for it.

Mid-Year ICD-10-CM Update: April 1, 2026

While CPT evaluation codes didn’t change, there’s a mid-year update most practices overlook. CMS posts a mid-fiscal-year ICD-10-CM update effective April 1, 2026. New and revised diagnosis codes in this release apply to dates of service from April 1, 2026, through September 30, 2026.

Make sure your EHR, practice management system, and clearinghouse all load this update on time. The ICD-10 codes paired with your 97162 evaluations must reflect the current code set. An outdated diagnosis code on an otherwise clean 97162 claim triggers a denial that has nothing to do with the evaluation itself. It’s entirely about the diagnosis code file your system is running.

This is the kind of denial that frustrates billing teams because the evaluation documentation is perfect, the modifier is correct, and the code selection is right. But the claim still bounces because nobody updated the ICD-10 table in the PM system. Mark April 1 on your calendar now.

Top 5 Denial Reasons for CPT Code 97162, and How to Prevent Each One

Most 97162 denials fall into the same five categories. None of them require complex solutions. Every single one is preventable with a consistent pre-submission process.

Here’s what goes wrong and how to stop it before the claim leaves your office.

Denial 1: Documentation Doesn’t Support Moderate Complexity

What happens: The payer reviews the evaluation note and determines documentation only supports low complexity. Claim gets downcoded to 97161 or denied outright.

Why it happens: The note uses vague language like “patient has multiple medical issues” instead of naming specific comorbidities. Exam sections list “ROM tested, strength tested” without objective measurements. Clinical rationale doesn’t explain why the presentation is evolving.

Prevention: Every 97162 CPT code evaluation note must name one to two specific comorbidities, document three or more exam elements with measurable values (degrees, grades, standardized test scores), and explicitly describe what’s changing in the patient’s condition. Vague language is a downcode waiting to happen.

Denial 2: Cloned or Template Notes

What happens: Identical evaluation language appears across multiple patient records. Medicare’s text-matching algorithms flag the pattern. Targeted medical review and recoupment follow.

Why it happens: Templates get used without patient-specific customization in every field. Staff copies yesterday’s note and changes the name and date.

Prevention: Templates are fine as frameworks. But every measurable value, comorbidity reference, and clinical rationale statement must be unique to the patient. If notes for a 24-year-old athlete and a 78-year-old with COPD read identically, that’s a credibility problem auditors will flag. Cloned notes remain one of the most visible forms of 97162 CPT code misuse.

Denial 3: Missing KX Modifier Above $2,480

What happens: Patient’s cumulative annual therapy spend crosses the 2026 KX threshold ($2,480 for combined PT and SLP). Nobody appended KX. Automatic denial with no human review.

Prevention: Set an EMR alert that triggers when a patient reaches $250 below the threshold. In multi-discipline practices tracking PT and SLP under the same threshold, make sure your tracking system combines both disciplines’ charges. Tracking PT alone misses the trigger point when SLP charges push the total over.

Denial 4: Wrong Provider Type on the Claim

What happens: Rendering NPI on the 97162 line belongs to a PTA. PTAs can’t perform evaluations. Immediate denial.

Prevention: Build this check into scheduling, not claim review. Evaluation visits go exclusively to licensed PTs. In multi-provider and multi-discipline practices where scheduling systems serve multiple provider types, configure the system to restrict evaluation appointment slots to qualified clinicians only. Catch it at scheduling and you’ll never see this denial again.

Denial 5: Bundling Violations on Evaluation Day

What happens: Practice bills 97750 or manual muscle testing codes separately alongside 97162 billing on the same date. CMS considers those assessments inclusive within the evaluation. Denied as bundled.

Prevention: Formal testing performed during the evaluation is part of the evaluation service, not a separate charge. If standalone formal testing is clinically necessary, schedule it for a subsequent visit. Billing it on eval day is a guaranteed denial.

These five categories account for the majority of 97162 claim denials across practice types. The pattern is the same whether you’re a two-therapist private clinic or a 50-provider hospital system. Fix the process, and the denials stop.

If these denial patterns look familiar, they’re costing your practice more than the lost reimbursement. Every denial burns staff time on investigation, appeals, and resubmission. Claimmax RCM’s pre-submission claim scrubbing catches coding errors, missing modifiers, and documentation gaps before claims reach the payer.

97162 Compliance Framework: Audit Risk Scoring and Internal Review Protocols

Billing 97162 CPT code evaluations correctly isn’t just about getting paid. It’s about staying off the audit radar. Medicare contractors don’t randomly select practices for review. They use data, and if your billing patterns look unusual compared to regional norms, you’ll hear from them.

Here’s how to assess your risk and build an internal review process that catches problems before an external auditor does.

Understanding Your Practice’s 97162 Audit Risk Profile

Medicare contractors track the ratio of 97162 (moderate) to 97161 (low) and 97163 (high) claims submitted by each provider. A practice where 95% of evaluations are billed as 97162 with minimal use of the other two codes raises a statistical red flag.

That flag doesn’t mean moderate complexity evaluations are wrong. It means the distribution suggests a coding pattern rather than genuine clinical variation. Real patient populations produce a mix of complexity levels. When the billing data doesn’t reflect that mix, auditors notice.

The national average distribution for PT evaluation codes shows approximately 20% to 25% low complexity (97161), 55% to 65% moderate complexity (97162), and 15% to 20% high complexity (97163). Practices whose ratios fall significantly outside these ranges face increased probability of Targeted Probe and Educate (TPE) reviews.

Know your numbers before someone else looks at them for you.

Internal Audit Protocol for 97162 Claims

A quarterly internal review catches documentation and coding issues while they’re still fixable. Here’s a five-step process you can start this quarter:

Step 1. Pull your 97161, 97162, and 97163 distribution report from your billing system. Compare your ratios to the national averages above. Flag any provider whose moderate-complexity ratio exceeds 80%.

Step 2. Random sample five to 10 evaluation notes per provider per quarter. For each note, verify three things: are one to two comorbidities specifically named? Are three or more exam elements documented with objective measurements? Does the clinical rationale explicitly describe an evolving presentation?

Step 3. Check modifier compliance across the sampled claims. Confirm GP is on every Medicare line. Verify KX is appended for patients above $2,480. Confirm Modifier 59 or XE is applied when 97140 appears on the same date.

Step 4. Review NCCI edit denial trends from the past quarter. Identify which code combinations are generating denials and whether your team is applying the correct modifiers or billing incompatible codes together.

Step 5. Benchmark against payer-specific denial rates. If one payer denies 97162 claims at a significantly higher rate than others, investigate whether there’s a payer-specific documentation or modifier requirement your team is missing.

This five-step review takes approximately two to three hours per quarter per provider. That’s a small investment compared to the alternative. Recoupment demands for systematic coding errors can reach into six figures, and by the time you receive one, the audit period typically covers 12 to 24 months of claims.

Finding your own problems first is always cheaper than having a payer find them for you.

Related Physical Therapy CPT Codes

CPT code 97162 doesn’t exist in isolation. It’s part of a larger family of evaluation, re-evaluation, and treatment codes that practices bill together regularly. Understanding how these procedure codes for physical therapy relate to each other, and to OT and SLP evaluation codes, prevents coding errors and helps multi-discipline practices bill accurately across all three disciplines.

CPT Code	Description	Discipline	Complexity / Use Case
97161	PT Evaluation, Low Complexity	PT	Stable condition, one to two exam elements
97162	PT Evaluation, Moderate Complexity	PT	Evolving condition, 3+ elements, one to two comorbidities
97163	PT Evaluation, High Complexity	PT	Unstable, 4+ elements, 3+ comorbidities
97164	PT Re-Evaluation	PT	Significant, unexpected condition change
97165	OT Evaluation, Low Complexity	OT	OT equivalent of 97161
97166	OT Evaluation, Moderate Complexity	OT	OT equivalent of 97162
97167	OT Evaluation, High Complexity	OT	OT equivalent of 97163
97168	OT Re-Evaluation	OT	OT equivalent of 97164
92521	SLP Evaluation of Speech Fluency	SLP	Fluency disorder assessment
92522	SLP Evaluation of Speech Production	SLP	Articulation and phonological assessment
92523	SLP Evaluation of Speech and Language	SLP	Comprehensive speech-language eval
97110	Therapeutic Exercise	PT/OT	Strength, ROM, endurance (timed)
97140	Manual Therapy	PT/OT	Joint mobilization, soft tissue (timed)
97530	Therapeutic Activities	PT/OT	Functional task training (timed)
G0283	Electrical Stimulation (Unattended)	PT/OT	E-stim modality

Why include SLP codes in a PT billing guide? Because multi-discipline practices need to understand how all three disciplines’ evaluation codes interact on the same date of service. Each discipline gets its own evaluation code per date, provided separate providers, separate documentation, and separate medical necessity are established.

The “Discipline” column matters more than it looks. When your billing team processes claims for a multi-discipline evaluation day, knowing which codes belong to which discipline prevents modifier mismatches. GP goes on PT lines, GO on OT lines, and GN on SLP lines. A 97162 billed with GN instead of GP denies immediately, and that error happens more often than you’d expect in practices with shared scheduling and billing systems.

For treatment codes like 97110, 97140, and 97530, remember the NCCI bundling rules covered earlier in this guide. Each one interacts differently with 97162 on the same date of service, and the fix for bundling edits isn’t the same across all of them.

Frequently Asked Questions About CPT Code 97162

What is the 97162 CPT code?

CPT code 97162 is a medical billing code from the American Medical Association (AMA) used to report a moderate-complexity physical therapy evaluation. It requires documented assessment of three or more body system elements, one to two comorbidities or personal factors influencing the plan of care, and moderate clinical decision-making for an evolving patient presentation. Introduced in 2017, it replaced part of the legacy single-code structure (97001) with a tiered complexity system that separates evaluations into low, moderate, and high categories.

What is the difference between 97161 and 97162?

CPT 97161 covers low-complexity PT evaluations: stable clinical presentation, one to two examination elements, no significant comorbidities. CPT code 97162 applies to moderate complexity: three or more examination elements, one to two comorbidities, and an evolving presentation requiring more clinical reasoning. The code is determined by documented complexity, not by session duration. A 30-minute evaluation on a stable patient with a straightforward complaint is still 97161, regardless of how thorough the exam was.

How often can 97162 be billed?

CPT 97162 is billed once per evaluation session as a service-based, untimed code. That means one unit per initial evaluation per discipline per date of service. If a patient returns after discharge, a new initial evaluation (97161 to 97163) may be appropriate rather than a re-evaluation (97164), depending on clinical circumstances and documented medical necessity. The key factor is whether the patient has been formally discharged from the previous episode of care.

How many units are allowed for 97162?

One unit per date of service per provider. CPT 97162 is untimed, so the 8-minute rule doesn’t apply. The Medically Unlikely Edit (MUE) caps 97162 at one unit per encounter. There’s no clinical scenario where billing multiple units on the same date is appropriate. Verify the current quarter’s MUE through CMS, as tables update quarterly and limits can change.

Can you bill 97162 and 97140 together?

Yes, but an NCCI Procedure-to-Procedure edit exists between CPT 97162 and 97140. Append Modifier 59 or an X-modifier (XE, XS, XP, or XU) to the 97140 line, not to 97162. Without the modifier, CMS automatically denies the manual therapy code. Documentation must support that the evaluation and manual therapy addressed distinct clinical purposes. The modifier goes on the treatment code every time.

Can you bill 97162 and 97530 together?

Not with a simple modifier bypass. Per APTA’s NCCI guidance (January 2020), NCCI edits between 97530 (therapeutic activities) and PT evaluation codes (97161 to 97163) can’t be overridden with Modifier 59 or X-modifiers. When both are billed on the same date for the same patient, the evaluation code takes priority and the 97530 line is denied. Schedule therapeutic activities for a separate date of service when clinically appropriate. This is a different rule than the 97140 edit, and confusing the two is a common and costly mistake.

What does evolving clinical presentation mean?

An evolving clinical presentation means the patient’s condition has changing characteristics rather than remaining stable. Pain levels fluctuate between visits. New functional limitations emerge. Weight-bearing tolerance shifts. Vital signs change in response to comorbidities or activity levels. If the presentation is predictable and unchanged visit to visit, that points to low complexity (97161). The evolving nature of the condition is one of the three required pillars for 97162 billing, and your documentation needs to describe specifically what’s changing and how it affects the treatment approach.

What are the CPT code 97162 billing guidelines?

Billing 97162 requires documentation of all three complexity pillars: one to two comorbidities in the patient history, examination of three or more body system elements with objective measurable findings, and moderate clinical decision-making for an evolving presentation. Medicare requires Modifier GP on the claim line. The code is billed once per evaluation, is untimed (the 8-minute rule doesn’t apply), and shouldn’t be billed alongside formal assessment codes like 97750 on the same date. CMS considers those tests inclusive within the evaluation.

What is a re-evaluation in physical therapy?

A re-evaluation is a comprehensive reassessment performed when a patient experiences a significant, unexpected change in condition. It’s billed under CPT 97164 and is distinct from a progress note, which documents expected, incremental changes within an ongoing plan of care. Re-evaluations require the same clinical reasoning as initial evaluations and must be documented as medically necessary. Using 97164 when a progress note would suffice increases audit risk, because payers view unnecessary re-evaluations as a utilization concern.

What are the three categories of clinical assessment for PT evaluations?

The three assessment categories are: (1) patient history, including personal factors and comorbidities; (2) examination of body systems, covering tests and measures of structures, functions, activity limitations, and participation restrictions; and (3) clinical decision-making, evaluating the complexity of the presentation and determining the plan of care. The documented level across all three categories determines whether the evaluation is coded as 97161, 97162, or 97163. The lowest qualifying category sets the code ceiling, not the highest. If two pillars support moderate complexity but the third only supports low, the correct code is 97161.

Does 97162 require a referral or prior authorization?

Medicare doesn’t require a physician referral for outpatient physical therapy evaluations under the direct access provisions most states have adopted. Commercial plans are a different story. Many require a referral, prior authorization, or both before covering PT services. Failing to verify these requirements before the evaluation creates authorization-related denials that are entirely preventable with a pre-visit eligibility and benefits check.

What ICD-10 codes are commonly billed with 97162?

Common ICD-10 pairings include M54.50, M54.51, or M54.59 (low back pain, laterality-specific), M25.511 (shoulder pain), S83.511A (ACL sprain), M62.81 (generalized muscle weakness), R26.89 (gait abnormalities), and G81.90 (hemiplegia). The ICD-10 code must support the medical necessity of the evaluation. A mismatch between the diagnosis and documented findings triggers claim denials. One important note: M54.5 as a standalone code was retired. Always use the expanded M54.50 (unspecified), M54.51 (right side), or M54.59 (left side) codes per current ICD-10-CM guidelines.

How to bill 97162 correctly?

To bill CPT 97162 correctly, follow these seven steps: (1) Confirm evaluation documentation supports moderate complexity across all three pillars: history, examination, and clinical decision-making. (2) Append Modifier GP on every Medicare claim line. (3) Add KX if the patient has exceeded the $2,480 annual therapy threshold. (4) Verify the rendering NPI belongs to a licensed PT, not a PTA. (5) Check NCCI edits for any treatment codes billed on the same date. (6) Submit with the ICD-10 code that matches documented clinical findings. (7) For hospital outpatient departments, verify whether your MAC requires Modifier CO on the professional component. That seventh step gets missed in most billing guides because they’re written for private practice only.

Protecting Your Practice Revenue with Accurate 97162 Billing

Everything in this guide comes back to six fundamentals that determine whether your 97162 CPT code claims pay cleanly or create problems downstream.

1. The lowest pillar sets the code. All three complexity criteria, history, examination, and clinical decision-making, must independently support moderate complexity. If any one falls to low complexity, the correct code is 97161. No exceptions.

2. Modifiers aren’t optional. GP goes on every Medicare PT claim. KX kicks in at $2,480. Modifier 59 or an X-modifier is required when 97162 billing includes 97140 on the same date. In hospital outpatient settings, verify CO requirements with your MAC.

3. NCCI edits change quarterly. Check current edit tables every 90 days. Pay particular attention to the 97162 plus 97530 pairing, which can’t be bypassed with modifiers. Schedule those services on separate dates.

4. 2026 97162 CPT code reimbursement is essentially flat. The higher conversion factor ($33.40) got offset by the 2.5% RVU efficiency adjustment. At approximately $101.20 per evaluation nationally, there’s no margin for revenue leakage from coding errors or missed modifiers.

5. Practice setting affects billing complexity. Private clinics, hospital OPDs, SNFs, and multi-discipline facilities each face different operational requirements for the same code. What works in one setting doesn’t automatically translate to another.

6. Compliance dates are non-negotiable. KX threshold: $2,480. Targeted Medical Review: $3,000. Telehealth PT flexibilities expired January 30, 2026. Mid-year ICD-10-CM update: April 1, 2026. Miss any of these and the denials are automatic.

Get these six things right and your 97162 claims will process cleanly across every payer and every practice setting.
