About Q4141: AlloSkin AC skin substitute
Q4141 reports AlloSkin AC supplied for a wound, billed by square-centimeter unit alongside the related skin-substitute application procedure.
Q4141 identifies AlloSkin AC, a human skin allograft used as a wound-covering product. It may be used in outpatient wound care for wounds such as diabetic foot ulcers or venous leg ulcers. Wound-care physicians, podiatrists, and surgeons may apply it as part of a treatment plan. The application procedure and the product are distinct services for reporting purposes.
Report Q4141 with the primary skin-substitute application procedure, using units that reflect the square-centimeter amount documented as supplied. The record should identify AlloSkin AC, the treated wound, the amount used, and the associated application. CMS treats Q4141 as an add-on: it is billed only with a primary procedure and paid within that procedure’s global period. It is a technical-component-only code, with interpretation represented by a separate code. CMS assigns practice-expense RVUs and no physician-work RVUs to Q4141.
