HCPCS code Q4226: MyOwn skin, per square centimeter2026 Medicare rate & RVUs in Missouri

CMS doesn’t publish an office rate for Q4226 in Missouri.

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

What Q4226 covers

Q4226 identifies MyOwn skin, a skin item reported with harvesting and preparation included. The code's measurement basis is the square centimeter of MyOwn skin furnished. Select this code for MyOwn rather than another named skin or amniotic product; identical area units do not identify the same product.

CMS assigns Q4226 physician fee schedule status E, excluding it from the physician fee schedule. If Medicare covers the item or service, it pays under another payment method. In the HCPCS pricing file, Q4226 is classified as a Part B drug; when covered, Medicare generally pays from CMS's quarterly ASP drug pricing files. Coverage is left to the Medicare contractor's judgment. Report quantity in square centimeters; one unit represents one square centimeter.
