Summary & Overview
HCPCS A4510: Surgical Stockings, Full Length, Each
HCPCS Level II code A4510 identifies a single full-length surgical stocking used for compression and post-operative support. Nationally, this code matters because surgical stockings are a common durable medical supply prescribed in perioperative care, for venous thromboembolism prevention, and for chronic venous disease management. Proper coding ensures accurate coverage determinations and claims processing for a high-volume, low-cost supply item.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise review of payer coverage patterns, typical sites of service, and clinical contexts in which A4510 is used. The publication also summarizes benchmarks for utilization and reimbursement where available, highlights policy considerations that affect coverage and documentation, and provides clinical context about indications for full-length surgical stockings.

Clinical & Coding Specifications
Clinical Context
A patient with chronic venous insufficiency or post-thrombotic syndrome presents to an outpatient vascular clinic for compression therapy. The treating clinician assesses the patient’s lower-extremity edema and prescribes full-length surgical stockings to provide graduated compression from the foot to the thigh. The typical workflow includes: initial evaluation by a vascular medicine physician, physician assistant, or wound care nurse; measurement of limb circumference and length for sizing; fitting and patient education on donning, doffing, wear schedule, skin care, and replacement intervals; documentation of indication and sizing in the medical record; and dispensing or ordering of a single stocking (HCPCS Level II code A4510) with billing to the patient’s insurer. Typical site of service is an outpatient clinic, vascular/wound care center, durable medical equipment supplier, or hospital outpatient department when provided at discharge or during a clinic visit. Common clinical scenarios include chronic venous insufficiency with leg edema, varicose veins with edema, lymphedema management after surgery, prevention of venous thromboembolism in ambulatory high-risk patients when compression stockings are indicated, and adjunctive therapy for venous stasis ulcers under wound care protocols. Patient education and follow-up to assess fit and skin integrity are standard parts of the encounter.
