About Q4312: Acesso AC wound product by area
Q4312 reports Acesso AC wound product by square centimeter when furnished with a primary wound application procedure.
Q4312 identifies the Acesso AC product used as a skin substitute or wound-covering material. It is reported by the clinician or facility furnishing the product during wound care, such as treatment of a chronic ulcer. The product code is distinct from the procedure that prepares the wound and applies the material; that procedure is selected according to the treated site and wound area.
Report the quantity in square centimeters and retain documentation identifying Acesso AC, the amount furnished, and the treated wound. CMS classifies Q4312 as an add-on code: submit it with a primary procedure, and its payment falls within that procedure’s global period. CMS also classifies it as technical-component-only, with a separate code covering interpretation. For example, the primary application procedure may be 15271 for an eligible trunk, arm, or leg site, or 15275 for an eligible head, face, neck, hand, foot, or genital site.
