What Q4263 covers
Q4263 identifies Surgraft TL, a wound-graft product reported by the square centimeter. It may be used in wound care, including treatment of chronic wounds such as diabetic foot ulcers or venous leg ulcers. Wound-care physicians, podiatrists, and surgeons may furnish or apply the product in an office, clinic, or hospital setting as part of a wound-treatment procedure.
Report Q4263 only with a primary procedure, and select that procedure for the service performed and the treated site and area. The product record and clinical documentation should identify Surgraft TL, the wound treated, and the quantity used so the billed square-centimeter units are supported. CMS treats Q4263 as an add-on paid within the primary procedure's global period. It is a technical-component-only code; a separate code covers interpretation.

Q4263 billing questions
Can Q4263 be reported by itself?
No. CMS classifies Q4263 as an add-on, so it must be billed with a primary procedure.
How should the unit count be determined?
The code is per square centimeter. Document the Surgraft TL quantity used and the treated wound area to support the reported units.
Does Q4263 include interpretation?
No. CMS identifies Q4263 as technical-component-only; a separate code covers interpretation.
How does Q4263 differ from Q4268 or Q4269?
These are separate product-specific Surgraft codes: Q4263 identifies TL, Q4268 identifies FT, and Q4269 identifies XT. Report the code matching the product furnished.
What supports reporting Q4263 with the primary procedure?
The record should identify Surgraft TL, the wound and treatment provided, the primary procedure, and the square-centimeter quantity used.
