What Q4273 covers
Q4273 identifies the Esano AAA product supplied for wound coverage, measured in square centimeters. It represents the product, not the clinician’s work to prepare the wound or apply the material. Wound-care clinicians and surgeons may use the product in office-based wound care or hospital settings as part of a documented wound treatment. The application procedure is reported separately.
Report the measured product area in square centimeters and identify the wound and product in the record. Q4273 is an add-on code and must be billed with a primary procedure; CMS pays it within that procedure’s global period. CMS classifies Q4273 as technical-component-only, with interpretation covered by a separate code. Do not treat the Q4273 line as the professional interpretation or as a substitute for the wound-application procedure.
