What Q4333 covers
Q4333 identifies Ardeograft as the wound graft product furnished, measured by square centimeter. It is a product-supply code rather than a code for the clinician’s application work. Physicians and other qualified clinicians may use the product during wound-care procedures; the specific primary procedure depends on the treated site and wound area. Keep the product record and wound documentation linked to the service date so the billed product can be matched to the procedure.
Report Q4333 only with a primary procedure, such as the applicable skin-substitute application code, and use units reflecting the square centimeters represented by the product. Documentation should identify Ardeograft, the treated wound and site, the amount used, and the associated application procedure. CMS treats Q4333 as an add-on code paid within the primary procedure’s global period. CMS also classifies it as technical-component-only, with interpretation covered by a separate code.

- Q4334 identifies Amnioplast 1, while Q4333 identifies Ardeograft. The product name on the supply record determines which code to report.
Q4333 billing questions
Which application code should accompany Q4333?
Pair it with the primary skin-substitute application procedure that fits the wound’s site and area. Q4333 is not reported by itself.
How should units be calculated?
The code is measured per square centimeter. Report units that correspond to the Ardeograft product represented on the claim.
What documentation supports Q4333?
Document the product as Ardeograft, the wound and treated site, the square-centimeter amount, and the related application procedure.
Is the application work included in Q4333?
Q4333 identifies the product supply, while the primary procedure represents the application service. CMS pays Q4333 within that procedure’s global period.
How does Q4333 differ from Q4334?
Q4333 identifies Ardeograft; Q4334 identifies Amnioplast 1. Select the code for the product actually furnished, not simply because both are reported per square centimeter.

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
