HCPCS A6509: Compression Burn Garment Vest, Upper Trunk to Waist, Custom Fabricated
HCPCS Level II code A6509 identifies a custom-fabricated compression burn garment that covers the upper trunk to the waist and includes arm openings (vest). This code is used to bill for therapeutic compression vests intended for management of burn-related scarring and edema and for shaping during the rehabilitation phase. Nationally, custom compression garments are an important component of post-burn care and durable medical equipment billing, impacting clinical recovery pathways and supply costs across payer systems.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find: benchmarks for utilization and coverage patterns across major payers; clinical context on the garment’s role in scar management and rehabilitation; and operational details relevant to billing and documentation. The publication highlights common billing considerations for custom-fabricated therapeutic garments and summarizes payer coverage landscapes and policy attributes where available.
This summary is intended for clinicians, billing professionals, and policy analysts seeking a concise reference on HCPCS Level II code A6509, its clinical purpose, and the payer environment affecting access and reimbursement for custom compression vests.

Clinical & Coding Specifications
Clinical Context
A patient with extensive hypertrophic or contracted burn scars of the upper torso presents for custom compression garment fitting. Typical patients include adults or children after deep partial-thickness or full-thickness burns who have completed acute wound closure and initial scar maturation (usually 2–6 weeks post-epithelialization) and require a medically prescribed custom-fabricated compression vest to manage hypertrophic scarring, control edema, and improve contour and function. The clinical workflow begins with a burn or plastic surgery clinic visit for scar assessment and documentation of medical necessity, including photographs, prior treatments, and functional limitations. A prescription for a custom compression garment coded as A6509 is written by the treating clinician. A certified fitter or orthotist performs body measurements or molding to fabricate the vest. The custom garment is manufactured, delivered, and fitted; the clinician documents fit, pressure tolerance, and patient education on wear schedule (typically 23 hours/day initially) and skin care. Follow-up visits assess scar response, garment adjustments, and potential replacement needs over the course of months to years depending on scar progression.
