Pt eval mod complex 30 min
CPT 97162 is used when a physical therapist performs a 30-minute evaluation of a patient with moderate complexity issues, requiring more assessment than a basic evaluation but less than the most complex cases.

Billing tips
Document all three complexity criteria: clinical presentation (3+ elements), patient history (2-3 personal factors/comorbidities), and examination findings requiring moderate clinical decision-making
Impact: Missing complexity justification causes downcoding to 97161 ($75.66), resulting in $22.35 loss per evaluation
Always append modifier GP to identify the service as physical therapy; most payers require this modifier for proper adjudication
Impact: Claims without GP modifier face automatic denial or incorrect processing, delaying payment 30-60 days
Bill 97162 only once per episode of care per discipline; re-evaluations use 97164, not repeat 97162
Impact: Duplicate 97162 billing within same episode triggers automatic denials and potential audit flags
Ensure the full 30-minute time requirement is documented; time includes face-to-face assessment, standardized testing, and clinical decision-making (not documentation time)
Impact: Insufficient time documentation can result in downcoding or denial; verify actual therapy time meets threshold
Use standardized outcome measures and document specific scores (LEFS, NDI, TUG, etc.) to support moderate complexity classification
Impact: Objective measures strengthen medical necessity and reduce audit risk by 40-60% based on OIG guidance
Do not bill 97162 on the same date as 97161 or 97163; select the single most appropriate complexity level based on complete evaluation
Impact: Billing multiple evaluation codes same day results in all but one being denied as duplicates
Common denials
Medical necessity not supported—documentation does not justify moderate complexity classification
How to appeal: Submit appeal with highlighted documentation showing 2-3 comorbidities/personal factors, evolving clinical presentation, and moderate decision-making complexity. Include standardized test scores and treatment plan modifications. Reference CMS guidelines defining moderate complexity criteria from CR 10186.
Duplicate service—97162 billed more than once during same episode of care
How to appeal: If legitimate: provide documentation proving separate episode of care with discharge and new physician referral. Include dates of discharge from previous episode and new condition/injury. If re-evaluation: correct claim to use 97164 instead of 97162 and resubmit.
Missing or incorrect modifier GP causing claim to reject or process incorrectly
How to appeal: Resubmit corrected claim with GP modifier appended. Include cover letter explaining administrative error. For Medicare, use CMS-1500 box 19 or electronic equivalent to note corrected claim.
Service bundled with treatment codes or E/M service on same date
How to appeal: Evaluations are separately payable from treatment. Submit documentation showing distinct evaluation service. If bundled with physician E/M, clarify that PT evaluation is different service by different provider. Add modifier 59 if appropriate for distinct service and resubmit.
Frequently asked questions
What is the difference between CPT 97161, 97162, and 97163?
These are three complexity levels for physical therapy evaluations. 97161 ($75.66) is for low complexity with stable conditions and 1-2 personal factors. 97162 ($98.01) is for moderate complexity with evolving presentations and 2-3 comorbidities. 97163 ($129.36) is for high complexity with unstable conditions and 3+ comorbidities. The code selection is based on clinical presentation complexity, patient history factors, and examination findings—not just time spent.
How much does Medicare pay for CPT 97162 in 2025?
Medicare pays $98.01 for CPT 97162 in 2025 based on the national average rate. This applies to both facility and non-facility settings. The payment is based on 3.03 total RVUs multiplied by the 2025 conversion factor of $32.3465. Actual reimbursement may vary by geographic locality due to practice expense and malpractice adjustments.
Can you bill 97162 and treatment codes on the same day?
Yes, you can bill 97162 with treatment codes (97110, 97112, 97116, 97140, etc.) on the same day. The evaluation is separately payable from therapeutic interventions. However, if performing both evaluation and treatment on the initial visit, document them as distinct services with separate time allocations and ensure the evaluation meets the full requirements for 97162 independently.
How often can you bill CPT 97162 for the same patient?
Bill 97162 only once per episode of care per discipline. An episode of care typically ends with formal discharge. If the patient returns after discharge for a new condition or significant time has passed with a new referral, you can bill 97162 again as a new episode. For progress assessments during ongoing treatment, use re-evaluation code 97164 instead.
What documentation proves moderate complexity for 97162?
Document 2-3 personal factors or comorbidities (diabetes, obesity, depression, work restrictions), an evolving clinical presentation with changing symptoms (3+ elements like pain variability, functional decline, multiple body regions), and examination findings requiring moderate clinical decision-making. Include standardized outcome measures with scores, treatment plan modifications based on findings, and clear rationale for selecting moderate versus low or high complexity.
Do physical therapy assistants bill CPT 97162?
No, PTAs cannot perform or bill evaluations independently. Only licensed Physical Therapists can perform and bill 97162. The evaluating PT must complete all components including clinical decision-making, diagnosis determination, and plan of care development. PTAs can perform re-assessments under supervision, but initial and comprehensive evaluations require PT credentials.
What modifier is required for CPT 97162?
Modifier GP is required for Medicare and most payers to identify 97162 as a physical therapy service under the PT benefit. Without GP, claims may deny or process incorrectly. Modifier 59 may be added if billing 97162 with another evaluation or service that would typically bundle, but this is rare. Always verify payer-specific modifier requirements as some commercial plans have different rules.
