Summary & Overview
HCPCS A4600: Sleeve for Intermittent Limb Compression Device, Replacement Only
HCPCS Level II code A4600 designates a replacement sleeve for intermittent limb compression devices, a durable medical equipment (DME) accessory used to manage limb edema and support venous circulation. Nationally, this code matters because replacement components are commonly billed separately from the compression device itself, affecting DME expense and continuity of therapy for patients requiring ongoing limb compression.
Key payers addressed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare and Medicare. The summary highlights typical coverage considerations such as medical necessity for continued therapy, documentation of prior device supply, and proper coding of replacement parts versus initial device claims.

Clinical & Coding Specifications
Clinical Context
A patient with chronic venous insufficiency or at high risk for deep vein thrombosis presents for ongoing use of a pneumatic intermittent limb compression device. The device requires replacement sleeves due to wear, contamination, or loss. Typical patients include postoperative orthopedic patients, medically ill hospitalized patients requiring prophylaxis, or ambulatory patients with venous stasis disease using home compression devices. The clinical workflow: a clinician (vascular medicine, physical medicine and rehabilitation, home health nurse, or durable medical equipment supplier) documents the medical necessity for continued compression therapy, confirms the existing device model and sleeve size, obtains an order for replacement sleeve A4600 (sleeve for intermittent limb compression device, replacement only, each), verifies payer coverage and any required prior authorization, supplies the sleeve to the patient or facility, and documents the dispense, device serial/model, and patient instruction for safe use and infection control. Typical site of service is inpatient hospital, outpatient clinic, surgical center, or the patient’s home via durable medical equipment delivery.
