What Q4274 covers
Q4274 identifies the Esano AC product supplied for wound coverage. A clinician may apply it to a wound as part of a skin-substitute procedure, such as treatment of a chronic ulcer. This code represents the product quantity, not the clinician’s wound preparation or application service. The application procedure is reported separately according to the site and area treated.
Report the units from the documented square centimeters of Esano AC furnished for the procedure, and retain the product record and wound-area documentation to support the quantity. Q4274 is an add-on code and must be reported with a primary procedure; its payment is within that procedure’s global period. CMS classifies it as technical-component-only, with a separate code covering interpretation.
