About Q4399: Summit FX wound product per area
Report Q4399 for Summit FX wound product by square centimeter when it is supplied with a primary wound procedure.
Q4399 identifies Summit FX, a wound-care product reported by the square centimeter. It is used when a clinician applies the product to a wound, such as a chronic ulcer, in an outpatient wound clinic or hospital setting. The code represents the product rather than the clinician’s wound assessment or the work of applying it.
Report the quantity in square centimeters and pair Q4399 with the primary procedure, as CMS classifies it as an add-on code. CMS pays it within that procedure’s global period. CMS also designates Q4399 as technical-component-only, with a separate code covering interpretation. Documentation should identify Summit FX, the treated wound, the amount supplied or used, and the primary procedure performed.
CMS billing rules for Q4399

- Add-on code: billed only together with a primary procedure and paid within that procedure's global period.

Q4399 billing questions
When should Q4399 be selected instead of another Summit code?
Use Q4399 when the product furnished is Summit FX. Summit AAA and Summit AC have separate HCPCS codes; select the identifier that matches the product used.
Can Q4399 be billed by itself?
No. CMS classifies it as an add-on code, so it must be billed with a primary procedure.
How is the quantity reported?
The descriptor is per square centimeter. Document the Summit FX area supplied or used and report the corresponding quantity.
How does the global-period rule affect payment?
CMS pays Q4399 within the global period of the primary procedure. It is not paid as a stand-alone service.
What does the technical-component designation mean?
CMS identifies Q4399 as technical-component-only and states that a separate code covers interpretation. The product and its quantity should be documented distinctly from any separately coded interpretation.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
