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.
