Summary & Overview
HCPCS L3674: Shoulder Orthosis, Abduction (Airplane) Design
HCPCS Level II code L3674 denotes a custom-fabricated shoulder orthosis in an abduction (airplane) design with a thoracic component and support bar, including fitting and adjustment. This device is used to maintain shoulder abduction and stabilization after complex shoulder injuries, reconstructive surgery, or when prolonged positioning is required. Nationally, billing clarity for such specialized orthoses matters because appropriate coding affects device access, supplier reimbursement, and continuity of post-operative care.
Key payers analyzed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for L3674, expected sites of service, and the common modifiers associated with durable medical equipment billing. The publication also outlines benchmark considerations and policy updates that influence coverage determination and claims adjudication for custom shoulder orthoses.
This resource helps clinical administrators, orthotics suppliers, and billing professionals understand where L3674 fits in orthotic service lines, what to expect in terms of service delivery, and which national payers are most likely to appear in coverage discussions. Data not available in the input for payer-specific coverage rules, reimbursement rates, associated taxonomies, and ICD-10 pairings are noted where applicable.

Clinical & Coding Specifications
Clinical Context
A 52-year-old patient presents to an orthopedic durable medical equipment (DME) clinic two weeks after an open rotator cuff repair and subacromial decompression. The surgeon requests a postoperative shoulder abduction orthosis to maintain the operated shoulder in an abducted and slightly externally rotated position to protect the repair during the early healing phase. The DME specialist evaluates the patient, documents surgical details, shoulder range of motion, pain level, and measurements for a custom-fabricated abduction sling/orthosis. Fitting and adjustment are performed in clinic; the device includes a thoracic component and support bar (airplane design) to offload tension on the repair and limit adduction. The orthotist instructs the patient and caregiver on donning/doffing, skin checks, wear schedule, and follow-up for adjustments. Typical site of service is an outpatient DME clinic, orthopedic clinic, or hospital outpatient department when provided at discharge.
