About Q4435: Renati membrane wound product
Q4435 reports Renati membrane by square centimeter when the product is furnished for wound coverage with a separately reported application procedure.
Q4435 identifies Renati membrane furnished for wound coverage, measured by the product area in square centimeters. It represents the product, not wound preparation or the clinician’s application service. In outpatient wound care, podiatry, or surgical settings, a treating clinician may use the membrane as part of care for a chronic or difficult-to-heal skin wound. The product and the procedure used to apply it are distinct claim elements.
Report the units supported by the square-centimeter amount of product furnished, and document the product, wound, treated area, and related application procedure. CMS classifies Q4435 as an add-on code: it must be billed with a primary procedure and is paid within that procedure’s global period. It is technical-component-only; a separate code covers interpretation. Do not submit Q4435 as a standalone product line.
