What Q4384 covers
Q4384 identifies the Axolotl Dual Ultimate product supplied for wound care, with units based on square centimeters. Wound-care clinicians and surgeons may use it when treating wounds such as chronic lower-extremity ulcers. The product code represents the wound product, not the application service itself; the clinical record should identify the wound, product used, and area represented by the reported units.
This is an add-on code, so report it only with an appropriate primary procedure. Its payment is handled within that procedure’s global period. CMS classifies Q4384 as technical-component-only, with interpretation covered by a separate code. The record should support the product selection, the related primary wound procedure, and the square-centimeter quantity. Do not use Q4384 in place of the procedure code for applying the product.
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.

Q4384 billing questions
Can Q4384 be reported by itself?

Which primary procedure should accompany Q4384?
Pair it with the appropriate wound-product application procedure, selected for the wound’s anatomic site and treated area. For example, billing code 15271 or 15275 may be relevant depending on those factors.
How are units determined?
The code is measured per square centimeter. Document the product and the square-centimeter quantity represented by the reported units.

No. Q4384 identifies the product; report the appropriate primary procedure for the application.
