Clinical & Coding Specifications
Clinical Context
A 45-year-old patient presents to an outpatient orthopedics clinic after a midshaft clavicle fracture and associated shoulder girdle strain following a bicycle fall. The treating orthopedic surgeon evaluates the patient, documents range of motion limitations and pain, and determines conservative management is appropriate. A prefabricated figure-of-eight shoulder orthosis (abduction restrainer) made of canvas and webbing is selected L3660 to limit scapular protraction and support clavicular alignment. The orthosis is fit and adjusted in clinic by a licensed orthotist or trained clinical staff, who confirm fit, provide wearing instructions, skin care guidance, and arrange follow-up. Typical workflow elements include order entry by the surgeon, medical necessity documentation in the chart, device provision and fitting in the clinic or durable medical equipment vendor location, and billing for the off-the-shelf orthosis using HCPCS code L3660 with applicable modifier(s) and the corresponding diagnosis code(s) on the claim. Typical sites of service are outpatient orthopedics clinics, ambulatory surgical centers for post-operative care, and durable medical equipment supplier locations when dispensed off-the-shelf.
