About Q4394: Surgraft ACA wound graft material
Reports Surgraft ACA wound-graft material by square centimeter when this specific product is used with a primary wound-application procedure.
Q4394 identifies Surgraft ACA wound-graft material by square centimeter; it represents the product, not wound-bed preparation or graft application. It is reported when a practitioner places this specific material over a wound, commonly in outpatient wound care for difficult-to-heal ulcers. The treating physician, podiatrist, or other qualified practitioner selects and applies the graft. The product name matters because nearby Q codes identify other products or Surgraft variants.
Report Q4394 with the primary procedure that applies the graft, not as a stand-alone service. Document the product used, the treated wound area, and the quantity applied so the reported square-centimeter units can be supported. CMS classifies Q4394 as an add-on code: it is billed only with a primary procedure, and its payment falls within that procedure’s global period. CMS also classifies it as technical-component-only; a separate code represents interpretation. The application code describes the service, while Q4394 identifies the material.

Q4394 billing questions
How is Q4394 distinguished from Q4393?
Both are Surgraft product codes, but Q4394 identifies Surgraft ACA and Q4393 identifies Surgraft AC. Use the code that matches the product label and documentation.
Can Q4394 be billed without a wound-application procedure?
No. CMS identifies it as an add-on code, so it must be billed with a primary procedure that applies the graft.
How should the units be supported?
Document the Surgraft ACA product and the square-centimeter quantity applied. The record should also identify the treated wound area.
Does Q4394 include the graft application service?
No. Q4394 identifies the material; the primary procedure reports the application service. The product code is paid within that procedure’s global period.
What does technical-component-only mean for this code?
CMS classifies Q4394 as technical-component-only, with interpretation represented by a separate code.
Where these rates come from
