Clinical & Coding Specifications
Clinical Context
A 42-year-old patient presents to an outpatient orthotics clinic after distal humerus fracture with residual elbow flexion weakness and joint stiffness despite initial immobilization and therapy. The orthopedic surgeon prescribes a dynamic adjustable elbow flexion-only orthosis to assist active elbow flexion, provide controlled range-of-motion, and protect soft tissues during progressive rehabilitation. The device E1804 (dynamic adjustable elbow flexion only device, includes soft interface material) is fabricated by a certified orthotist and fitted in the clinic. The clinical workflow includes a referral from the surgeon or physical therapist, initial evaluation by the orthotist, measurement and customization of the device, fitting and education on donning/doffing and adjustment, documentation of functional goals and range-of-motion targets, and scheduled follow-up visits for adjustment and reassessment. Typical sites of service are outpatient orthotics/prosthetics clinics, orthopedic surgery clinics, hospital outpatient departments, and skilled rehabilitation facilities when outpatient fitting is arranged.
