About Q4342: Theramend skin substitute product
Q4342 reports Theramend wound-covering product by square centimeter when supplied with an appropriate primary wound or skin-substitute application procedure.
Q4342 identifies Theramend, a wound-covering tissue product, measured by the square centimeter. It represents the product supplied for application to a wound, not the clinician’s work applying it. Wound care clinicians, surgeons, and other practitioners who treat wounds may use it in outpatient or facility settings when Theramend is applied as part of a wound treatment. The procedure code describes the application; Q4342 identifies the specific product used.
Report the quantity in square centimeters and document the product name, the treated wound, and the amount applied. Pair Q4342 with the applicable primary application procedure, such as CPT 15271 or 15275 when appropriate to the site and wound area. CMS treats this as an add-on code paid within the primary procedure’s global period, not as a standalone service. CMS classifies it as technical-component-only; a separate code covers interpretation. CMS assigns no physician-work RVUs to Q4342.
