HCPCS code Q4236: Carepatch, per square centimeter2026 Medicare rate & RVUs

Medicare pays $127.26 for Q4236 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 Q4236 covers

Q4236 identifies Carepatch supplied for wound treatment, measured by the area furnished in square centimeters. It is a product code, not the code for applying the material. Clinicians may furnish it during wound care in an outpatient clinic or surgical setting when Carepatch is used as part of a primary wound procedure.

Report the documented Carepatch quantity in square centimeters and pair Q4236 with the applicable primary procedure; the record should identify the product and the amount used. CMS treats Q4236 as an add-on, so it is billed only with a primary procedure and payment falls within that procedure’s global period. The code is technical-component-only; a separate code covers interpretation. The Carepatch line therefore represents the product, not interpretation.
