This code captures a commonly used supply in compression therapy for venous insufficiency, lymphedema management, and post-procedural edema control. Its national relevance stems from frequent use in outpatient clinics, home health programs, and durable medical equipment suppliers where compression supplies are integral to ongoing wound and vascular care.
Key payers in scope include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of coverage considerations and coding context for A6594, plus what typical sites of service and clinical scenarios prompt use of this supply code.

Clinical & Coding Specifications
Clinical Context
A patient with chronic venous insufficiency and symptomatic lower‑extremity edema presents to a wound care clinic for management. The clinician assesses venous stasis changes, mild to moderate pitting edema, and dependent aching. After evaluation, the clinician determines that a gradient compression bandaging system is appropriate to reduce edema and support venous return. A bandage liner for the lower extremity, coded as A6594, is applied beneath compression bandages to provide skin protection, moisture control, and improved graduated compression interface. Typical workflow: the patient is triaged and vitals obtained; the clinician documents wound/edema assessment and measurements; the skin is cleansed and protected; the A6594 bandage liner is applied to the calf/ankle/foot as indicated; overlying compression wrap or multilayer system is applied; documentation includes diagnosis code(s), item code A6594, quantity, laterality (RT or LT if applicable), servicing provider taxonomy, and any applicable modifier (for example RT, LT, or NU for new supplies). Typical site of service is an outpatient wound care clinic, durable medical equipment supplier visit, home health visit, or outpatient physician office visit when supplies are furnished and applied during treatment.
