What Q4408 covers
Q4408 identifies the Xwrap Hydro wound product supplied for application to a wound. It may be used in wound-care treatment, including care of chronic ulcers such as diabetic foot or venous leg ulcers. A clinician performing the wound procedure typically documents the wound site and the product used; the code describes the product supply rather than the wound-care clinician’s evaluation or application service.
Report the product quantity in square centimeters and pair Q4408 with the primary procedure. The record should support the exact product and the amount used. CMS classifies Q4408 as an add-on code, so it is billed only with a primary procedure and paid within that procedure’s global period. It is also technical-component-only; a separate code covers interpretation. Select a different product code when the product actually furnished is a different Xwrap formulation.
