Clinical & Coding Specifications
Clinical Context
A patient presents to an outpatient vascular surgery or lymphedema specialty clinic for management of chronic lower extremity edema and venous insufficiency. The clinician documents a history of varicose veins, post-thrombotic syndrome, or primary lymphedema with persistent swelling despite conservative measures. A fitted gradient compression garment is ordered for daytime use to provide graduated pressure for edema control, improve venous return, reduce pain and heaviness, and support wound healing after venous ulcer treatment. The clinical workflow includes: initial evaluation and measurement by the provider or certified fitter; documentation of medical necessity (diagnosis, conservative therapy tried, functional limitation); selection of garment style and size; ordering using HCPCS level II code A6549; delivery and patient education on wear schedule and garment care; follow-up visit to assess fit, tolerance, and clinical response. Typical site of service is an outpatient clinic, durable medical equipment supplier, or certified compression garment fitter location.
