    Clinical & Coding Specifications

    Clinical Context

    A 58-year-old patient with a transradial amputation presents to an outpatient orthotics and prosthetics clinic for fitting and fabrication of an upper-extremity addition: a quick-disconnect lamination collar with coupling piece (manufacturer example: Otto Bock). The clinical workflow includes prosthetist evaluation, measurement and molding of the residual limb, selection of appropriate coupling and collar components to mate an existing socket to an interchangeable terminal device, fabrication (lamination) of the composite collar, curing and finishing, and a final fitting visit to verify alignment, range of motion, secure quick-disconnect engagement, and patient comfort. Follow-up visits for minor adjustments and training in donning/doffing and maintenance are typical. Typical sites of service are outpatient prosthetics/orthotics clinics or specialized rehabilitation prosthetics labs; fittings and adjustments may also occur in skilled nursing facilities or inpatient rehabilitation units when coordinated with the prosthetist and treating physician.
