Functional Capacity Evaluation (FCE) vs. Independent Medical Examination (IME)
Functional Capacity Evaluation (FCE)
A performance-based assessment of the work a person can safely do, usually conducted by a licensed physical or occupational therapist, for which a 2018 best practices guideline recommends an allowance of up to 8 hours over one or two days (Allison et al., 2018).

A physician-led examination and records review that provides diagnostic and causation opinions, typically in a single session (American Medical Association, 2023).
| Dimension | Functional Capacity Evaluation (FCE) | Independent Medical Examination (IME) |
|---|---|---|
| Examiner | OT or PT | Physician |
| Duration | Up to 8 hours over 1 or 2 days | 30-90 minutes, typically single session |
| Primary output | Safe maximum demonstrated physical capacities | Diagnostic and causation opinion |
| Methodology | Standardized physical tests with effort/consistency measures | History, examination, record review |
| Typical use | Establish work capacity restrictions | Establish diagnosis, causation, prognosis |
When to use Functional Capacity Evaluation (FCE)
Use an FCE when physical work capacity must be quantified for return-to-work or vocational opinion purposes.
When to use Independent Medical Examination (IME)
Use an IME when diagnostic, causation, or prognosis questions need physician-level opinion, often on behalf of the defense.
Where they overlap
Both examine the claimant. They answer different questions: FCE quantifies physical capacity; IME addresses medical questions. In catastrophic cases, both are often performed. KWVRS conducts IMEs for New York and New Jersey matters only.
Frequently Asked Questions
Can an IME include functional testing?
Some IME physicians perform or order functional testing, though dedicated FCEs by OTs and PTs produce more detailed and standardized physical capacity data.
