About Q4179: Flowerderm wound covering
Report Q4179 for each square centimeter of Flowerderm used as a wound covering with a qualifying primary wound procedure.
Q4179 identifies Flowerderm, a wound-care product reported by the square centimeter. It is used when a clinician applies the product to a wound as part of wound treatment. Wound-care clinicians and surgeons may use it in outpatient wound clinics, physician offices, or hospital settings. The code identifies the product quantity, not the clinical work of assessing or treating the wound.
Report units according to the square centimeters of Flowerderm used, and document the product and treated area. CMS identifies Q4179 as an add-on code: bill it only with a primary procedure, and payment falls within that procedure’s global period. CMS also classifies it as technical-component-only, with interpretation covered by a separate code. Pair it with the appropriate primary wound procedure for the service performed; the product code does not replace that procedure.
