About Q4375: Duograft AC wound graft product
Reports Duograft AC product used in wound treatment, measured by the number of square centimeters supplied for application with a primary procedure.
Q4375 identifies Duograft AC, a wound graft product reported by the square centimeter. It represents the product used during wound treatment, not the clinician’s work to prepare or apply it. Wound-care clinicians, surgeons, and podiatrists may use graft products in outpatient wound clinics or procedural settings; the code applies specifically when the product used is Duograft AC.
Report the quantity in square centimeters and pair Q4375 with the applicable primary procedure; it is not billed by itself. Documentation should identify Duograft AC, the treated wound, the amount used, and the associated procedure. CMS classifies this as an add-on code paid within the primary procedure’s global period. It is also a technical-component-only code: interpretation is covered by a separate code, not Q4375.

How is the quantity determined?
Report the Duograft AC product quantity by the square centimeter. Document the amount used and identify the product.
Which code reports the graft application?
Use the applicable primary wound-application procedure code. For example, CPT 15271 or 15275 may apply depending on wound location and the procedure’s criteria.
Does Q4375 include interpretation?
No. CMS classifies Q4375 as technical-component-only; a separate code covers interpretation.
How does Q4375 relate to the primary procedure’s global period?
CMS states that Q4375 is paid within the primary procedure’s global period and must be reported with that procedure.
