Summary & Overview
HCPCS Level II A6519: Gradient Compression Garment, Nighttime Use
HCPCS Level II code A6519 identifies a gradient compression garment intended for nighttime use, provided as a single item. Nationally, compression therapy is an important conservative treatment for lymphedema and venous disorders, and codes like A6519 enable standardized billing for durable medical equipment supplied for home use. This code matters because it affects coverage determinations, claims processing, and patient access to prescribed therapeutic garments.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna, UnitedHealthcare, and Medicare. Readers will find a concise overview of the code’s clinical purpose and expected site of service, typical payer considerations, and what to look for in documentation and billing. Coverage policies and medical necessity criteria vary by payer; this publication highlights benchmarking areas, common billing practices, and potential policy updates that influence reimbursement and utilization nationally.
The report also outlines practical context for clinicians and billing staff: where the garment is typically used (home/nighttime), how it is characterized in billing, and which stakeholders commonly engage with claims for therapeutic compression garments. Data not available in the input will be indicated where applicable in detailed sections.

Clinical & Coding Specifications
Clinical Context
A patient with chronic lymphedema of the lower extremity is fitted with a A6519 gradient compression garment intended for nighttime use. The patient typically presents to a vascular medicine clinic, plastic surgery clinic, or lymphedema therapy program after conservative measures (manual lymphatic drainage, daytime compression hosiery) provide incomplete control of nocturnal swelling. The clinical workflow includes: initial evaluation by the provider documenting diagnosis and justification for nighttime compression; measurement and fitting by a certified fitter or lymphedema therapist; prescription documentation signed by the treating provider specifying A6519, laterality if applicable, and intended use (nighttime); procurement through the durable medical equipment supplier; and follow-up visits to assess fit, skin integrity, and symptomatic response. Typical sites of service are outpatient specialty clinics (vascular medicine, wound/ostomy and continence clinics), lymphedema therapy centers, durable medical equipment supplier locations, and the patient’s home after delivery.
