About Q4304: Grafix Plus wound product by area
Reports the per-square-centimeter amount of Grafix Plus supplied for wound treatment when billed with the applicable primary application procedure.
Q4304 identifies Grafix Plus supplied for application to a wound. It is a product code, not the wound preparation or application service itself. Wound-care clinicians may use the product during treatment of open wounds, including chronic wounds managed in outpatient wound clinics or other settings. The product record and treatment note should make clear that Grafix Plus, rather than another wound product, was used.
Report the product quantity in square centimeters and pair Q4304 with the primary procedure that applies the product; it is an add-on and is paid within that procedure’s global period. Documentation should support the product used, the wound treated, and the amount supplied or applied. CMS classifies Q4304 as technical-component-only: the code represents the technical portion, while a separate code covers interpretation. The wound application service and the product quantity are distinct reporting elements.
