About Q4406: Xwrap Fenestra wound covering by area
Reports Xwrap Fenestra by square centimeter when this wound-covering product is used with a separately coded primary wound procedure.
Q4406 identifies the Xwrap Fenestra product supplied for wound coverage, measured by area in square centimeters. It is used in wound-care treatment when the clinician applies this specific product to a wound. Wound-care physicians and surgeons may use it in outpatient or facility settings; the code identifies the product rather than the wound assessment or application service.
Report Q4406 with the applicable primary procedure for applying the product, selected according to the wound’s site and treated area. The claim should identify Xwrap Fenestra and support the quantity billed with documentation of the product used and wound area treated. CMS classifies Q4406 as an add-on code, paid within the primary procedure’s global period. It is technical-component-only; a separate code covers interpretation.
