What Q4302 covers

Q4302 identifies Complete ACA, a skin-substitute product supplied for wound treatment. A clinician applies the material to a wound, commonly in a wound-care or surgical setting; the HCPCS code reports the product, not the clinician’s application service. The corresponding application procedure is reported separately. The product may be considered for wounds managed with a skin substitute, with selection based on the treating clinician’s plan and the product actually used.

Report the quantity in square centimeters and document the product, treated wound, amount supplied or applied, and associated application procedure. This is an add-on code: bill it only with a primary procedure, and Medicare payment falls within that procedure’s global period. CMS identifies Q4302 as technical-component-only, with interpretation covered by a separate code. The code has no physician work RVUs; its practice-expense RVUs represent the technical side of the service.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

Q4302 billing questions

Is Q4302 the wound application procedure?

No. Q4302 reports the Complete ACA product by square centimeter. Report the appropriate skin-substitute application procedure separately.

Can Q4302 be billed by itself?

No. CMS identifies it as an add-on code that must be billed with a primary procedure.

What quantity should the claim report?

Report the Complete ACA quantity in square centimeters. Documentation should identify the product and the amount supplied or applied to the treated wound.

How does the global-period rule affect payment?

Medicare pays Q4302 within the global period of the associated primary procedure; it is not a standalone service outside that procedure.

Does Q4302 include interpretation?

CMS classifies it as technical-component-only and states that a separate code covers interpretation.

How is Q4302 different from Q4303?

The codes identify different named products: Complete ACA and Complete AA. Select the code for the product actually used, rather than choosing by wound size.

Where these rates come from

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.
