What Q4322 covers
Q4322 identifies Caregraft, a wound product reported by square centimeter when used in wound treatment. It may be used in settings where clinicians apply wound products, such as outpatient wound clinics or hospital departments. The code represents the product, not the clinician’s wound assessment or the procedure that places it. The treating clinician’s procedure documentation should identify the product and the treated wound area.
Report Q4322 only with a primary procedure; CMS treats it as an add-on and pays it within that procedure’s global period. The application procedure is selected separately according to the treated site and wound area. Document the Caregraft used and the square-centimeter quantity reported. CMS classifies Q4322 as technical-component-only, with a separate code covering interpretation.
This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.
