Clinical & Coding Specifications
Clinical Context
A 56-year-old patient with chronic hip instability and abductor muscle weakness following a complex acetabular fracture repair is fitted for a custom-fabricated hip orthosis. The device is a static hip orthosis with abduction control, incorporating a pelvic band or spreader bar and thigh cuffs to maintain controlled hip abduction and limit adduction and internal rotation. The orthotist performs a comprehensive evaluation, takes measurements and casts or digital scans, fabricates the custom device, and performs an initial fitting and adjustment. Typical workflow steps include: referral from orthopedic surgery or physical medicine, pre-fit evaluation and documentation of functional limitations and prior treatments, measurement/scanning visit, fabrication (laboratory work), delivery and fitting visit with in-clinic adjustments, patient education on donning/doffing and skin checks, and follow-up visits for adjustment and reimbursement documentation. Typical sites of service are outpatient orthotics clinics, hospital-based orthotics/prosthetics departments, and specialized durable medical equipment providers associated with orthopedic practices.
