Ot eval high complex 60 min
CPT 97167 is for a complex occupational therapy evaluation that takes about 60 minutes, used when a patient has multiple health problems or conditions that make their assessment more complicated than a standard OT evaluation.

Billing tips
Document all three required complexity criteria: clinical presentation (history, comorbidities), clinical decision-making (multiple treatment options, unstable condition), and patient presentation (barriers to evaluation/treatment)
Impact: Failure to document all three areas is the #1 denial reason, resulting in downcoding to 97166 and loss of $23-27 per evaluation
Ensure 60 minutes of direct patient contact time is documented with start/stop times; do not include preparation, documentation, or coordination time in the 60 minutes
Impact: Insufficient time documentation triggers denials and audits; recovery audits frequently target time-based codes with 15-20% recoupment rates
Always append modifier GP for Medicare and Medicare Advantage plans to designate occupational therapy service under outpatient therapy cap
Impact: Missing GP modifier results in automatic denial; resubmission delays payment by 30-45 days on average
Bill 97167 only once per episode of care unless there is a significant change in condition requiring re-evaluation; use 97168 for re-evaluations
Impact: Duplicate 97167 codes within same episode trigger medical necessity reviews with 60-70% denial rates
Document specific standardized assessments used (COPM, FIM, AMPS, etc.) with scores and interpretation to justify high complexity level
Impact: Lack of objective assessment tools cited in 40% of downcoding decisions during audits
For Medicare patients, verify therapy cap threshold status and consider KX modifier when appropriate after cap is met
Impact: Services exceeding threshold without KX modifier (when medically necessary) result in payment denial; proper use maintains $100.60 reimbursement above threshold
Common denials
Insufficient documentation of complexity - payer downcodes to 97166 (moderate complexity) stating clinical presentation does not support high complexity designation
How to appeal: Submit detailed appeal with highlighted documentation showing: 3+ comorbidities affecting treatment, complex clinical decision-making (citing specific assessment findings and treatment alternatives considered), and patient barriers to care. Include comparative table mapping documentation to CPT descriptor complexity criteria. Success rate improves 70% with structured complexity matrix.
Time documentation missing or insufficient - claim denied for failure to document required 60 minutes of direct patient contact
How to appeal: Provide complete evaluation note with clearly documented start and stop times, breakdown of evaluation components by time, and attestation that 60+ minutes were medically necessary. Reference Medicare's guidance that typical time is 60 minutes but medical necessity drives service length. Include contemporaneous schedule/EMR timestamp if available.
Duplicate evaluation - denied as duplicate service when 97167 billed more than once in same episode without documented change in condition
How to appeal: Submit documentation clearly identifying significant change in patient condition (hospitalization, new diagnosis, functional decline, new complications) that necessitated complete re-evaluation rather than routine re-assessment. Include physician orders for new evaluation and explanation of why 97168 re-evaluation code was insufficient.
Missing or incorrect modifier GP - claim denied or processed incorrectly without occupational therapy designation
How to appeal: Submit corrected claim with modifier GP appended. Include cover letter explaining administrative error and requesting retroactive processing. Most payers allow one-time correction without penalty. For recurrent issues, audit claim scrubber settings in billing system.
Frequently asked questions
What is the difference between CPT 97167 and 97166?
CPT 97167 is for high complexity OT evaluations requiring assessment of patients with multiple comorbidities, complex functional deficits, or extensive clinical decision-making, while 97166 is for moderate complexity cases. The 97167 reimburses at $100.60 compared to 97166's lower rate, and requires documentation of complexity in clinical presentation, decision-making, and patient barriers to justify the higher level.
How long does a 97167 occupational therapy evaluation take?
CPT 97167 is a 60-minute evaluation code representing the typical time required for a high complexity OT assessment. The actual time must be at least 60 minutes of direct patient contact and should be documented with start/stop times. Time spent on preparation, documentation after the visit, or care coordination is not included in this 60-minute requirement.
Can 97167 be billed twice for the same patient?
Generally no - 97167 should only be billed once per episode of care. If re-evaluation is needed, use CPT 97168 instead. However, 97167 can be billed again if there is a significant documented change in the patient's condition (new diagnosis, hospitalization, major functional decline) that requires a complete new evaluation rather than a routine re-assessment.
What modifiers are required for CPT 97167?
Modifier GP is required for Medicare and most Medicare Advantage plans to designate the service as occupational therapy under the outpatient therapy benefit. Modifier CO may be required when a COTA performs part of the evaluation under OTR supervision. Other modifiers like 59 or 76 may be appropriate in specific circumstances when billing multiple procedures or repeat evaluations.
What does CPT 97167 pay in 2025?
The 2025 Medicare national average payment for CPT 97167 is $100.60 for both facility and non-facility settings. This is based on 3.11 total RVUs (1.54 work RVU, 1.53 practice expense RVU, 0.04 malpractice RVU) multiplied by the 2025 conversion factor of 32.3465. Actual payment varies by geographic locality and payer contract.
What documentation is required to bill 97167?
Documentation must justify high complexity through three elements: (1) clinical presentation showing multiple comorbidities or complex conditions, (2) clinical decision-making requiring extensive assessment and consideration of multiple treatment options, and (3) patient presentation factors creating barriers to evaluation/treatment. You must also document 60+ minutes of direct patient contact with start/stop times, standardized assessment tools with scores, comprehensive functional goals, and a detailed treatment plan.
Can occupational therapy assistants bill CPT 97167?
Certified Occupational Therapy Assistants (COTAs) can assist with performing components of the evaluation under appropriate OTR supervision per state practice act, but the occupational therapist (OTR) must establish the evaluation findings and plan of care. When a COTA participates, modifier CO should be appended. Medicare and most payers require the OTR to personally perform the clinical decision-making and establish the treatment plan for initial evaluations.
