    HCPCS Level II code L3670 describes a prefabricated, off-the-shelf shoulder orthosis for the acromio/clavicular region constructed of canvas and webbing; the service is an orthotic device fitting/supply typically used in outpatient clinics, durable medical equipment suppliers, or ambulatory care settings to provide support and immobilization of the shoulder complex following injury or surgery.

    Clinical & Coding Specifications

    Clinical Context

    A 54-year-old patient presents to an orthopedic clinic after a fall onto the shoulder with localized pain over the acromioclavicular joint and visible prominence of the distal clavicle. The orthopedist performs a focused shoulder exam, orders radiographs confirming a low- to moderate-grade acromioclavicular (AC) joint sprain without displaced fracture, and determines the patient is appropriate for conservative management. The clinic dispenses an off-the-shelf canvas and webbing AC shoulder orthosis (L3670) to immobilize and support the acromioclavicular region. The clinical workflow includes device selection, fitting and adjustment by clinical staff, patient education on wear time and skin checks, documentation of medical necessity (exam findings, imaging, functional limitations), and coding/billing to the patient’s insurer. Follow-up is scheduled in 1–2 weeks to assess pain, function, and need for continued orthotic use or escalation of care.
