Clinical & Coding Specifications

Clinical Context

A 32-year-old right-hand–dominant male presents to an orthopedic hand clinic after sustaining a closed nondisplaced transverse fracture of the second metacarpal (boxer-type variant) while punching a wall. After clinical evaluation and radiographs confirm alignment within acceptable parameters, the hand therapist or orthotist fits a prefabricated metacarpal fracture orthosis to immobilize the affected metacarpal and adjacent joints. The device represented by L3917 is a prefabricated hand orthosis that is trimmed, molded, bent, or otherwise customized by a clinician with expertise (orthotist, certified hand therapist, or occupational therapist) to achieve proper fit and immobilization.

The typical workflow: initial evaluation by the orthopedic surgeon or urgent care clinician, plain radiographs, decision for nonoperative management, referral to hand therapy or orthotics, customization and fitting of the prefabricated orthosis (L3917), patient education on wear schedule and skin checks, scheduled follow-up visits with repeat radiographs at 1–2 weeks and at union assessment (4–6 weeks). Documentation includes diagnosis, justification for orthosis, measurements, customization steps, device description, and follow-up plan.
