Summary & Overview
HCPCS Level II A6579: Gradient Compression Glove, Custom, Medium Weight
HCPCS Level II code A6579 identifies a custom, medium-weight gradient compression glove supplied per limb to manage lymphedema, edema, and other conditions requiring graduated compression. Nationally, this code matters because custom compression garments are frequently used in chronic care management and post-surgical rehabilitation, and they involve distinct coverage and documentation requirements compared with off-the-shelf items.
This analysis covers major national payers including Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context, typical sites of service, and payer coverage scope. The publication summarizes common billing practices, allowable service lines, and relevant reimbursement considerations where available. It also highlights places where policy variation is common and identifies areas where readers can expect differences in documentation or prior-authorization requirements.
The report is geared to clinicians, billing professionals, and policy analysts seeking a national perspective on coding, coverage patterns, and operational implications for provisioning custom gradient compression gloves under A6579. Data not available in the input is noted where applicable.
Billing Code Overview
HCPCS Level II code A6579 describes a gradient compression glove, custom, medium weight, each. This item is a custom-fitted compression garment designed to provide graduated pressure to the hand and wrist to manage lymphedema, edema, or related circulatory conditions. The service type is durable medical equipment (custom compression garment provision and fitting). The typical site of service is outpatient clinic, specialty durable medical equipment provider, or home health setting where custom measurement and fitting occur.
Clinical & Coding Specifications
Clinical Context
A patient presents to an outpatient orthotics and prosthetics clinic or a hand specialty clinic with chronic lymphedema of the hand, persistent digital swelling after trauma, or debilitating post-surgical edema limiting function. The clinician (hand therapist, certified prosthetist-orthotist, or orthopedic/hand surgeon) evaluates range of motion, limb measurements, skin integrity, and circulatory status. When off-the-shelf compression garments fail to provide adequate gradient compression or when unique hand anatomy requires individualized fit, a custom gradient compression glove is fabricated. The workflow includes initial assessment and measurement, ordering and documenting medical necessity, creation of a custom pattern by the orthotics technician, fitting and adjustment at a follow-up visit, patient education on wear schedule and skin care, and periodic reassessment for replacement or modification. Typical site of service is an outpatient clinic, orthotics/prosthetics facility, or specialty rehabilitation center. Typical patient scenario: a 62-year-old female with right upper-extremity post-mastectomy lymphedema with persistent hand swelling and reduced grip strength receives a custom medium-weight gradient compression glove billed with A6579 for the affected hand, with follow-up fitting and functional assessment documented in subsequent visits.
