Summary & Overview
HCPCS A6521: Gradient Compression Glove, Padded, Nighttime, Custom
HCPCS Level II code A6521 designates a custom, padded gradient compression glove for nighttime use. As a durable medical equipment item, this garment supports management of hand swelling and lymphedema by providing targeted, graduated compression during sleep. Nationally, coverage and utilization of custom compression garments affect access to conservative lymphedema care and can influence out-of-pocket costs for beneficiaries who require custom-fitted devices.
Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of typical coverage considerations for custom compression garments, common billing and coding context for durable medical equipment, and the clinical rationale for nighttime compression in edema management. The publication summarizes benchmark considerations, payer policy patterns, and areas where clinical documentation typically supports medical necessity determinations.
This summary provides clinicians, billing staff, and policy analysts with concise information on what A6521 represents, its role in outpatient and home-based care, and the types of policy and documentation issues that commonly arise with custom compression devices. Data not available in the input is noted where relevant in detailed sections.

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult with chronic lymphedema of the hand or forearm following cancer surgery or radiation who requires a custom, padded gradient compression glove for overnight use to reduce fluid accumulation and protect fragile skin. The patient is evaluated in an outpatient specialty clinic (such as physical medicine and rehabilitation, lymphedema clinic, or orthotics and prosthetics) where a certified lymphedema therapist or prosthetist performs a focused assessment of limb volume, skin integrity, sensation, and range of motion. Measurements and a custom pattern for the glove are taken during the initial visit. The custom garment is fabricated offsite by an orthotics/prosthetic vendor to the specified gradient compression levels and padded design for nighttime comfort. At a subsequent fitting visit, the clinician verifies fit, provides wear-time instructions (typically night use), documents functional benefit, and supplies education on skin care and signs of complications. Follow-up visits assess therapeutic response and need for garment adjustments or replacement.
