What Q4324 covers

Q4324 identifies AmnioTx, an amniotic tissue product used as a covering for skin wounds, including chronic or difficult-to-heal ulcers. It represents the product, not the clinician’s work to prepare the wound or apply the graft. Physicians and other qualified practitioners involved in wound care may use it in an office or facility setting as part of a graft application service.

Report the documented square centimeters of product used and pair Q4324 with the primary application procedure selected for the treated site and wound area; it is not a standalone service. Keep the product record and procedure note consistent about the product and amount applied. CMS treats Q4324 as an add-on paid within the primary procedure’s global period. It is also classified as technical-component-only, with interpretation covered by a separate code.

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.

Q4324 billing questions

Can Q4324 be reported by itself?

No. It is an add-on for the primary procedure that applies the graft, and CMS pays it within that procedure’s global period.

How should the quantity be reported?

Report the quantity in square centimeters. Documentation should identify AmnioTx and support the amount used for the graft application.

Is Q4324 the application procedure?

No. Q4324 identifies the AmnioTx product; a separate primary procedure reports application of the graft to the wound.

Does Q4324 include professional interpretation?

No. CMS classifies Q4324 as technical-component-only; a separate code covers interpretation.

How is Q4324 distinguished from Q4323 or Q4325?

These codes identify different wound products. Use Q4324 for AmnioTx, rather than selecting it based only on wound location or 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.
