About Q4401: Absolv3 wound product per square centimeter
Q4401 identifies Absolv3 wound product by square centimeter when it is used with a primary skin-substitute application procedure.
Q4401 identifies the Absolv3 product used to cover a wound; it is not the clinician’s application service. Clinicians providing wound care, including physicians and other qualified practitioners, may use it in an office or hospital outpatient setting for wounds such as diabetic foot or venous leg ulcers. The code’s unit is one square centimeter of product, so the claim should reflect the product and quantity used for the treated wound.
Report Q4401 only with the primary procedure for applying the product, selected for the wound site and area. Documentation should identify Absolv3, describe the wound and treated area, and support the billed square-centimeter units. CMS classifies Q4401 as an add-on code, with payment within the primary procedure’s global period. It is technical-component-only; a separate code covers interpretation.

Q4401 billing questions
When should Q4401 be chosen over Q4400 or Q4402?
Use Q4401 when Absolv3 is the product used. Q4400 identifies Polygon3, and Q4402 identifies Xwrap 2.0; report the product actually applied.
What primary service must accompany Q4401?
Q4401 is billed only with the primary procedure for applying the product. Select that procedure according to the wound site and area treated.
How are units determined?
The product is reported per square centimeter. Document the treated wound area and the quantity of Absolv3 used to support the units.
Does Q4401 represent the clinician’s application or interpretation?
No. Q4401 identifies the product and is technical-component-only; a separate code covers interpretation. The application is reported through the primary procedure.
