About Q4393: Surgraft AC wound graft product
Reports Surgraft AC graft material by square centimeter when supplied for wound coverage alongside a primary wound procedure.
Q4393 identifies the Surgraft AC graft product used to cover a wound. It represents the product, not the clinician’s wound preparation or application work. Wound-care clinicians and surgeons may use graft products in outpatient wound clinics, hospital outpatient departments, or other settings where a wound procedure is performed. The record should identify Surgraft AC and document the amount used and the wound treated.
Report Q4393 only with a primary procedure; CMS treats it as an add-on paid within that procedure’s global period. The unit basis is the product amount in square centimeters. Pair it with the applicable wound graft application procedure, such as 15271 for qualifying sites on the trunk, arms, or legs, or 15275 for qualifying sites on the head, face, ears, eyelids, nose, lips, or neck. CMS classifies Q4393 as technical-component-only, with a separate code covering interpretation.
