What Q4332 covers
Q4332 identifies Axolotl DualGraft wound graft material by the square centimeter. It represents the product, not the procedure that prepares a wound or applies the graft. Physicians and other qualified practitioners may use this material during wound care in settings where skin substitute products are applied, including treatment of chronic ulcers or other wounds requiring coverage. The product name on the package or product record helps distinguish this code from codes for other graft products.
Report Q4332 only with a primary procedure; CMS treats it as an add-on code, and payment falls within that procedure’s global period. Select the code by the product actually used, and report units in square centimeters supported by documentation of the product and amount used. The primary procedure represents the wound service; Q4332 represents the material. CMS classifies Q4332 as technical-component-only, with interpretation covered by a separate code.
