Coverage Criteria for FCE and Physical Performance Testing
Medically Necessary — Functional Capacity Evaluation (FCE)
Functional Capacity Evaluation (FCE) is considered medically necessary when ALL of the following are met:
FCE typically not indicated prior to 3 months post-injury unless significant documented change; limited to 2-4 hours per date of service and one evaluation every 12 months (exceptions reviewed individually). A FCE may extend beyond 4 hours or two days in select complex cases based on case complexity and availability of clearly defined work-related physical demands.
Not Medically Necessary
These are considered nonmedical, educational, or training in nature and therefore not medically necessary under this policy. Corresponding CPT codes (e.g., 97537, 97545, 97546) are categorized as educational/training and not covered when billed as FCE/testing.
Experimental, Investigational and/or Unproven
These devices are described in the literature but evidence does not demonstrate superior diagnostic utility or standardized procedures that alter clinical outcomes.
Covered when criteria met
Coverage expectations and conditions for FCE and testing services
Supports validity and appropriate test selection.
Time in direct contact determines units reported for 97750.
Devices include Biodex, Kin-Com, MedX, Isostation and are often applied around the knee or spine depending on the device and indication.
It would not be appropriate to report a code from the 95851-95852 series in addition to 97750. Services that are part of a routine assessment or re-evaluation of rehabilitation care should not be billed separately as a physical performance test/measurement. Direct one-on-one patient contact is required when reporting 97750 and documentation should support that the service was distinct from routine evaluation or treatment activities.
Mechanical quantitative muscle testing devices (for example, isokinetic machines such as Biodex or Kin‑Com, and spinal devices like MedX or Isostation) are described in this policy as instruments that may be used for objective testing and to generate comprehensive reports of torque, strength ratios, and performance at various speeds. When these devices are used for therapeutic exercise (strengthening or conditioning), billing should reflect therapeutic exercise services rather than the CPT codes intended for testing and measurement; the CPT codes in this guideline refer specifically to device use for testing/evaluation.
The peer-reviewed literature is limited regarding clinical outcome benefit of quantitative muscle testing devices compared with standard manual testing; documentation must therefore distinguish whether the device was used for evaluation (testing) versus therapeutic purposes to ensure appropriate coding and coverage.
Programs whose primary goal is returning an individual to work—such as vocational rehabilitation programs and work hardening programs—are considered nonmedical, educational, or training in nature and are not medically necessary under this policy. Corresponding CPT codes commonly used for these services (for example, 97537, 97545, 97546) are listed as educational/training and therefore not covered.
There is limited evidence in the published literature supporting the clinical benefit of quantitative muscle testing devices. Studies have not demonstrated these devices to be superior to standard manual muscle testing in improving health outcomes, and the evidence base is therefore judged insufficient. This limited evidence base supports cautious use and careful documentation when such testing is requested; lack of evidence alone does not automatically equate to denial, but payers may require clear justification of how the test results will change management.

| 97537 | Community/work reintegration training (eg, shopping, transportation, money management, avocational activities and/or work environment/modification analysis, work task analysis, use of assistive technology device/adaptive equipment), direct one-on-one contact, each 15 minutes |
| 97545 | Work hardening/conditioning; initial 2 hours |
| 97546 | Work hardening/conditioning; each additional hour (List separately in addition to code for primary procedure) |
| 97750 | Physical performance test or measurement (e.g., musculoskeletal, functional capacity), with written report; time based |
Referrals, Documentation, Billing, and Evaluator Requirements
Prior authorization and referral requirement
Under many benefit plans, coverage for Functional Capacity Evaluation (FCE) is subject to the applicable benefit plan's Short-Term Rehabilitative Therapy benefit and prior authorization/referral rules. When return-to-work services are covered by the member's benefit plan, FCE coverage is subject to the plan's short-term rehabilitative therapy benefits and any required prior authorization or referral.
- Claims submitted for services that are not accompanied by covered code(s) under this policy will be denied as not covered. Ensure the most appropriate CPT/HCPCS codes are used as of the date of service.
Referral required prior to FCE
A written referral (from a physician, carrier, or employer) must be forwarded to the evaluator prior to performing an FCE. The referral must explicitly state the purpose of the FCE and include clearly defined goals to guide test selection. Referral should identify the specific question(s) the FCE is intended to answer (for example: readiness to return to work, ability to perform specific job duties, work tolerance, or determination of restrictions).
- Referral must be received before the evaluation.
- Referral must define goals and purpose to guide test selection.
FCE referral and records review
The referral source and the evaluator should access and review any relevant medical records and work-related information prior to the FCE. This review should include prior attempts to return to work or prior FCEs (if occurred) and reasons for failure, comorbidities that could influence results, and clearly identified return-to-work goals and potential options.
- Evaluator should review relevant medical records, work duties, prior FCEs, and prior return-to-work attempts.
- Consider comorbidities and their potential influence on the FCE and return-to-work outcomes.
Required documentation and evaluator competencies
Evaluators must document required elements before, during, and after the FCE. Prior to the FCE the evaluator must obtain a subjective pain assessment including self-reported effect on functional abilities and activities of daily living, perform a screening examination, and obtain informed consent. Written reports are required and must include patient demographics, work history, indication for evaluation, type of evaluation performed, raw and tabulated data, normative data values and comparisons, and a narrative coversheet with results and recommendations.
- Document subjective interview and self-reported measures of disability.
- Document physical examination/screening and behavioral observations (pain behavior, effort).
- Include raw/tabulated data, normative comparisons, interpretation, and recommendations in the written report.
Documentation required for test/measurement procedures (CPT 97750)
As CPT 97750 is a time-based code, document all three time elements to support reporting: total time spent with the patient (including preparation), time spent performing the selected testing protocol, and time spent providing post-testing instructions. Time in direct patient contact determines the number of units reported. Include documentation of the testing protocol, reason for the test, separate measurement report (including any graphic reports), interpretation of data, and how results affect the plan of care (discharge, return to work/sport/ADL, or treatment modification). Failure to document these three time elements may result in denial.
- Total time with patient (including prep)
- Time performing the selected protocol
- Time providing post-test instructions
- Include testing protocols, raw/tabulated data, interpretation, and application to functional activity.
Evaluator qualifications
FCEs must be performed in their entirety by a licensed physical therapist or occupational therapist, or other licensed provider qualified by their scope of practice. Evaluators should demonstrate education, training and competencies relevant to the FCE system used (certification where required) and have experience (minimum of five satisfactorily performed FCEs). Proof of competency may include credentialing committee review of a sample of previous FCE reports.
- Performed in entirety by a licensed PT or OT or other licensed provider qualified by scope of practice.
- Evaluator education, training, certification (where required), and experience (>=5 completed FCEs) must be documented.
- Proof of competencies may include Credentialing and Risk Management Committee review of prior reports.
Billing differentiation for testing vs therapeutic use of muscle-testing devices
When quantitative muscle testing devices or isokinetic devices are used, distinguish therapeutic use from testing. If the device is used therapeutically (e.g., for strengthening as part of rehabilitation), bill using appropriate therapeutic exercise codes rather than testing/evaluation CPT codes. When used for testing/evaluation, document the specific protocols, speeds, measured torques, muscle strength ratios, and include comprehensive reports demonstrating results and interpretation.
- Therapeutic use of devices: bill as therapeutic exercise (do not use testing-specific CPT codes).
- Testing/evaluation use: document protocols, speeds, torques, and interpretive reports.
Background and Rationale
A Functional Capacity Evaluation (FCE) is a structured, multi‑component assessment used to objectively evaluate an individual’s ability to perform work‑related physical demands after musculoskeletal injury or medical rehabilitation. FCEs are typically performed when patients are medically stable but have ongoing functional limitations or when there is discrepancy between reported symptoms and observed function. They are used to inform return‑to‑work decisions, job modification needs, vocational planning, and medicolegal determinations.
FCEs should be performed by a qualified evaluator (for example, a licensed physical or occupational therapist) using a documented referral that clearly states the purpose and goals of the evaluation. The resulting written report should include raw/test data, standardized comparisons or norms, a narrative interpretation, and recommendations regarding functional abilities and impact on the plan of care. Typical FCE sessions are limited to 2–4 hours per date of service and are generally performed no more than once every 12 months unless an exception is clinically justified.
