About Q4429: DermBnd CHN or CHX skin substitute
Q4429 reports each square centimeter of DermBnd CHN or CHX supplied for a skin substitute application to a wound.
Q4429 identifies the DermBnd CHN or CHX product used when a clinician applies a skin substitute to a wound. It is a product code measured by area, rather than a code for the clinician’s application work. The product variant matters: other DermBnd variants have their own codes, so the product record should identify CHN or CHX.
Report units in square centimeters of DermBnd CHN or CHX used, supported by the product label, area measurement, wound site, and application record. CMS classifies Q4429 as an add-on code, so it must accompany a primary procedure and is paid within that procedure’s global period. CMS also designates it as technical-component-only; a separate code covers interpretation. The primary procedure documents the application, while Q4429 identifies the particular product and quantity.
