About Q4358: Xwrap Dual wound product
Reports the area of Xwrap Dual wound-care product used with a primary wound application procedure, measured in square centimeters.
Q4358 identifies the Xwrap Dual wound-care product by the area used, rather than the clinician’s work to prepare or apply it. It may be reported when a wound-care clinician or surgeon uses the product during treatment of a wound, including in an office or hospital outpatient setting. The clinical record should identify the treated wound and the product used.
Report the product with a primary application procedure; Q4358 is an add-on code and is not billed by itself. Document the quantity in square centimeters so the units match the area used. CMS places payment within the primary procedure’s global period. Q4358 is classified as technical-component-only, with a separate code covering interpretation.
