Clinical & Coding Specifications
Clinical Context
A patient with hemiparesis following a cerebrovascular accident (stroke) is seen in an outpatient durable medical equipment fitting clinic for arm positioning support. The clinician (prosthetist/orthotist or physical therapist) assesses the patient who reports difficulty maintaining the affected limb in a functional, comfortable position during sitting and transfers and who has shoulder subluxation pain. The clinician prescribes an arm trough accessory to be attached to a wheelchair or seating system to support the forearm and hand, reduce distal drifting, protect bony prominences, and decrease shoulder strain. The workflow includes: evaluation and measurement, documentation of functional limitations and trial of off-the-shelf supports if applicable, selection of E2209 (Accessory, arm trough, with or without hand support, each), obtaining prior authorization when required, fabrication or selection, fitting and adjustment, patient education on use and skin checks, and delivery with corresponding documentation of medical necessity and mobility/seating goals.
