Summary & Overview
HCPCS A6517: Gradient Compression Wrap, Below Knee, Custom
HCPCS Level II code A6517 identifies a custom, below-knee gradient compression wrap with adjustable straps intended for management of edema, venous insufficiency, lymphedema, and related lower-extremity conditions. Nationally, accurate coding for custom compression devices affects access to appropriate durable medical equipment and impacts coverage determinations, prior authorization workflows, and reimbursement for suppliers and clinicians.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical indications for custom gradient compression wraps, typical sites of service where these devices are supplied, and the role of HCPCS Level II coding in DME claims processing. The publication outlines common modifiers used with DME billing, payer coverage considerations, and coding nuances relevant to suppliers and billing staff.
The report provides benchmarks for claim handling and common administrative practices, highlights policy and documentation requirements that influence coverage, and summarizes clinical context for prescribing and fitting custom below-knee compression wraps.

Clinical & Coding Specifications
Clinical Context
A patient presents to an outpatient orthopedics or vascular surgery clinic with symptomatic unilateral lower extremity edema, venous insufficiency, or post-traumatic swelling after below‑knee surgery. The clinician evaluates circulation, assesses for wounds or grafts, and determines that a custom gradient compression wrap with adjustable straps is medically appropriate to provide graduated compression, reduce edema, protect skin grafts, and support ambulation. The device is measured and custom‑fabricated to the patient’s below‑knee anatomy. The typical clinical workflow includes evaluation and documentation of the indication and limb measurements, ordering the custom device, fitting and instructing the patient on donning/doffing and wear schedule, and scheduling follow‑up to assess fit, tolerance, and therapeutic response. The service is usually delivered in an outpatient durable medical equipment (DME) setting, orthotics/prosthetics clinic, wound care center, or outpatient surgical clinic, and may be billed per limb using the HCPCS Level II code A6517 with applicable modifiers for payer-specific circumstances.
