What Q4424 covers

Q4424 identifies Revive FT, a named skin-substitute product billed by square centimeter. It represents the product supplied for application to a wound, rather than the clinician’s wound-preparation or application service. Wound-care clinicians and surgeons may use the product as part of a wound treatment performed in an office or facility; the code identifies the product, not a particular wound site or clinical severity.

Report Q4424 with the primary procedure for applying the product, not by itself. The claim should identify the Revive FT product and document the quantity used in square centimeters, along with the wound and application service. Select the primary application code based on the applicable site and area criteria. CMS classifies Q4424 as an add-on code paid within the primary procedure’s global period. It is also a technical-component-only code; a separate code covers interpretation.

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.

Q4424 billing questions

Can Q4424 be billed by itself?

No. CMS identifies it as an add-on code, so report it with the primary procedure for applying the product.

How should the units be determined?

Use the documented amount of Revive FT supplied in square centimeters. The record should support the product identity and quantity reported.

Which application code should accompany Q4424?

Choose the primary skin-substitute application procedure according to the treated site and applicable area criteria. Q4424 reports the product, not the application service.

How does the global-period rule affect Q4424?

CMS pays this add-on product code within the primary procedure’s global period. It is not a standalone service outside that pairing.

What does technical-component-only mean for this code?

CMS classifies Q4424 as technical-component-only, with interpretation represented by a separate code.

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.
