About Q4328: Most wound product by area
Report Q4328 for the square-centimeter amount of Most wound product used with a separately coded skin-substitute application procedure.
Q4328 identifies Most, a wound-care skin substitute product, by the square centimeter. Wound-care physicians, surgeons, and other clinicians who apply skin substitutes may use it in outpatient wound clinics, offices, or hospital settings. The product amount is reported separately from the procedure used to prepare the wound and apply the graft; Q4328 represents the product, not the clinician’s application work.
Report the number of square centimeters of Most used, supported by documentation of the product and treated wound area. Select the separate application procedure based on the applicable body site and wound-area criteria. CMS identifies Q4328 as an add-on code: bill it only with a primary procedure, and payment is within that procedure’s global period. CMS also classifies it as technical-component-only; a separate code covers interpretation.
