Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What Q4357 covers

Q4357 identifies the Xwrap Plus wound matrix supplied for application to a prepared wound bed; it reports the product, not the wound-preparation or application work. A wound-care clinician or surgeon may use it during treatment of a wound such as a chronic lower-extremity ulcer. The application procedure and the product are represented separately on the claim, with the product quantity reported in square centimeters.

Report Q4357 only with a primary procedure, as CMS classifies it as an add-on code paid within that procedure’s global period. Documentation should identify Xwrap Plus, the wound site, the amount used, and the associated primary procedure; select the application code according to the treated body area and wound area. CMS classifies Q4357 as technical-component-only, with a separate code covering interpretation.
