What Q4402 covers
Q4402 identifies the Xwrap 2.0 wound-care product by the square centimeter. It represents the product, not the work of preparing the wound or applying material to it. Clinicians may use wound products during treatment of a wound in an office or facility setting; the product code is selected by the specific item furnished, not by wound size or severity alone.
Report the quantity in square centimeters and document the product identity and the amount used. This is an add-on code: it is reported only with a primary procedure, and its payment is within that procedure's global period. CMS classifies Q4402 as technical-component-only; a separate code covers interpretation. Do not use Q4402 in place of the primary wound procedure or to identify a different Xwrap product. The accompanying primary service and its documentation should support the product use and the reported quantity.

Q4402 billing questions
When should Q4402 be selected instead of another Xwrap code?
Use Q4402 when the product furnished is specifically Xwrap 2.0. Other Xwrap products have their own HCPCS codes, so select by the product identity rather than the wound's characteristics.
Can Q4402 be reported by itself?
No. CMS identifies it as an add-on code that must be billed with a primary procedure. Its payment is within that procedure's global period.
What quantity should be reported?
Report the amount of Xwrap 2.0 furnished in square centimeters. Documentation should identify the product and support the reported area.
Does Q4402 include the wound preparation or application service?
Q4402 identifies the product, not the clinical work of preparing the wound or applying it. Report the supported primary procedure with the product code.
How does the technical-component designation affect billing?
CMS classifies Q4402 as technical-component-only; a separate code covers interpretation. The product code itself does not represent that interpretation.
