About Q4320: Pellograft wound graft material
Q4320 reports Pellograft by square centimeter when the graft material is supplied for application to a wound during a qualifying primary procedure.
Q4320 identifies Pellograft supplied for wound coverage, measured by square centimeter. It is relevant when a clinician applies this graft material to a wound, such as a diabetic foot or venous leg ulcer. Wound-care physicians, surgeons, and podiatrists may provide these services in office, clinic, or hospital settings. The application procedure addresses placement of the graft; Q4320 identifies the Pellograft product used.
Report the product quantity in square centimeters and retain documentation identifying Pellograft and the amount used. Pair Q4320 with the appropriate primary application procedure; it is an add-on code and is paid within that procedure’s global period. CMS classifies Q4320 as technical-component-only, with interpretation covered by a separate code. The record should support both the wound treatment and the reported product quantity.

Q4320 billing questions
When should Q4320 be selected instead of another wound-graft product code?
Use Q4320 when the product supplied is Pellograft. Other product codes identify different named graft products, even when the unit basis is also square centimeters.
Can Q4320 be reported by itself?
No. CMS identifies it as an add-on code, so report it with the appropriate primary procedure for applying the graft.
How should units be determined?
The code is measured per square centimeter. Document the Pellograft quantity used in square centimeters; wound dimensions alone do not establish the amount of product reported.
Is interpretation included in Q4320?
CMS classifies Q4320 as technical-component-only and specifies that a separate code covers interpretation.
How does the primary procedure affect payment?
Q4320 is paid within the primary procedure’s global period. It must be reported with that primary procedure rather than as a standalone service.
