About Q4285: Nu-Dyn DL wound matrix supply
Reports Nu-Dyn DL or DL Mesh by square centimeter when the wound matrix is used with a primary wound application procedure.
Q4285 identifies Nu-Dyn DL or DL Mesh wound matrix by square centimeter for use with a wound-coverage procedure. The material is supplied for placement on a prepared wound bed in settings such as outpatient wound clinics, hospital outpatient departments, or surgical facilities. Wound-care physicians, surgeons, and podiatrists may use it when a graft or matrix application is selected; the product code is distinct from the clinician’s application service.
Report the measured square-centimeter quantity of the documented product with the applicable primary application procedure, not as a standalone service. The record should identify the product, wound site, treated surface area, amount used, and associated procedure. CMS classifies Q4285 as an add-on billed only with a primary procedure and paid within that procedure’s global period. It is technical-component only; a separate code covers interpretation. Select the primary application code based on the procedure performed and applicable site and wound-area criteria.
