HCPCS code Q4275: Esano ACA, per square centimeter2026 Medicare rate & RVUs

Medicare pays $127.26 for Q4275 nationally in the office. Local office rates run $109.31–$183.51.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What Q4275 covers

Q4275 identifies the Esano ACA wound product by area; it does not describe the clinician’s wound assessment or the application procedure. Wound care physicians, podiatrists, surgeons, and other clinicians may use it in outpatient wound care, including treatment of chronic wounds such as diabetic foot ulcers or venous leg ulcers. The product is placed on a prepared wound as part of the treatment plan.

Report the product only with a primary procedure, and document the product variant and square-centimeter quantity used so the claim can be reconciled with the clinical record and product packaging. CMS identifies Q4275 as an add-on code, with payment within the primary procedure’s global period. CMS also classifies it as technical-component-only, with interpretation covered by a separate code; Q4275 does not represent a professional interpretation.
