What Q4191 covers
Q4191 identifies Restorigin wound-covering material in one-square-centimeter units. Wound care clinicians, surgeons, and podiatrists may use it when treating wounds that require coverage with a skin substitute product, including in outpatient wound clinics and hospital outpatient departments. The product supply is distinct from the procedure used to prepare the wound and apply the covering.
Report Q4191 with the primary application procedure; it is not billed alone. Select the application procedure according to the wound location and treated area, and document the product, wound site, measured area, quantity used, and application. CMS classifies Q4191 as an add-on code paid within the primary procedure’s global period. It is also technical-component-only; a separate code covers interpretation.
