What Q4304 covers

Q4304 identifies Grafix Plus supplied for application to a wound. It is a product code, not the wound preparation or application service itself. Wound-care clinicians may use the product during treatment of open wounds, including chronic wounds managed in outpatient wound clinics or other settings. The product record and treatment note should make clear that Grafix Plus, rather than another wound product, was used.

Report the product quantity in square centimeters and pair Q4304 with the primary procedure that applies the product; it is an add-on and is paid within that procedure’s global period. Documentation should support the product used, the wound treated, and the amount supplied or applied. CMS classifies Q4304 as technical-component-only: the code represents the technical portion, while a separate code covers interpretation. The wound application service and the product quantity are distinct reporting elements.

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.

How to choose

15271Skin substitute graft
15271 reports the primary application service for an eligible site and wound area; Q4304 reports the Grafix Plus product quantity and is an add-on.
15275Skin substitute
15275 is an application procedure for specified sites such as the face, hands, feet, or genitalia. Q4304 identifies the product used, not the application service.
Q4305Wound allograft
Q4305 identifies a different wound product billed per square centimeter. Use the code matching the product actually furnished rather than substituting it for Grafix Plus.

Q4304 billing questions

Can Q4304 be billed by itself?

No. CMS identifies it as an add-on code, so report it with the applicable primary wound application procedure.

How is the quantity reported?

The descriptor is per square centimeter. Documentation should support the amount of Grafix Plus supplied or applied to the wound.

Does Q4304 include the wound application?

No. Q4304 identifies the product; the primary procedure represents the application service. For an appropriate site and size, 15271 may be the primary application code.

Is an interpretation included in Q4304?

No. CMS classifies Q4304 as technical-component-only and specifies that a separate code covers interpretation.

What documentation helps support Q4304?

Record the product as Grafix Plus, identify the treated wound, and document the quantity used in square centimeters along with the associated application procedure.

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.
