Clinical & Coding Specifications
Clinical Context
A 45-year-old construction worker presents for a work-related functional capacity evaluation requested by his employer and occupational health coordinator. The provider performs a focused assessment to determine work fitness, disability status, and any medical restrictions related to a shoulder strain sustained on the job two weeks prior. The visit includes review of medical records, a directed history, targeted physical examination of the musculoskeletal and neurologic systems, and documentation of work-related limitations and recommended restrictions. The provider completes required paperwork for return-to-work clearance and communicates findings to the employer and case manager. Services are furnished for either a newly referred worker or an established patient and may occur in an outpatient clinic, occupational medicine office, employer site visit, or inpatient setting when medically necessary.
