HCPCS code Q4368: Wound matrix, amchothick, per square centimeter2026 Medicare rate & RVUs

Medicare pays $127.26 for Q4368 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 Q4368 covers

Q4368 identifies the Amchothick wound-covering product, reported by square centimeter. Wound-care clinicians, podiatrists, and surgeons may apply this type of material to a prepared wound bed, including during treatment of chronic ulcers. The code represents the product supplied, not the wound preparation or application procedure itself.

Report Q4368 only with a primary procedure; CMS treats it as an add-on and pays it within that procedure’s global period. The technical-component-only designation means the code covers the technical portion, with interpretation represented by a separate code. Documentation should identify Amchothick by name, the wound treated, the quantity supplied or used, and the related primary procedure. Follow the applicable product and claim instructions when translating the documented quantity into units.
