What Q4297 covers
Q4297 identifies Emerge Matrix, a skin substitute product measured by the square centimeter for wound coverage. It represents the product supplied, not the clinician’s work to prepare or apply it. Wound care clinicians, surgeons, and podiatrists may use a matrix during treatment of wounds such as diabetic foot or venous leg ulcers when the product is selected for the wound.
Report units based on the square centimeters of Emerge Matrix supplied, and pair the product code with the appropriate primary skin substitute application procedure, such as billing code 15271 for an eligible trunk, arm, or leg site or billing code 15275 for an eligible other site. Documentation should identify Emerge Matrix, the wound site, the amount used, and the related application. CMS classifies Q4297 as an add-on code paid within the primary procedure’s global period. It is technical-component-only; a separate code covers interpretation.
