    Clinical & Coding Specifications

    Clinical Context

    A typical patient is a 68-year-old post-stroke patient referred to outpatient physical therapy for persistent right-sided hemiparesis and difficulty with activities of daily living. At the start of the therapy episode the therapist performs a standardized functional status assessment to document the patient’s primary functional limitation (for example, transfers, ambulation, or upper-extremity self-care). The therapist records the current status using validated outcome measures and documents baseline functional level in the medical record to meet reporting requirements. The workflow includes initial evaluation, identification of the primary functional limitation, selection of interventions, periodic reassessment at established reporting intervals (for example, every 10 visits or at discharge), and documentation of change in the primary functional limitation over time. Typical sites of service are outpatient rehabilitation clinics, skilled nursing facilities, and home health settings where physical or occupational therapy is delivered.
