About Q4415: AlexiGuard ST-L wound graft per square centimeter
Report Q4415 for each square centimeter of AlexiGuard ST-L used with a primary graft application procedure, such as coverage of a leg or foot wound.
Q4415 identifies the AlexiGuard ST-L product used during a skin-substitute graft application. A clinician may apply this product as wound coverage, for example during treatment of a chronic lower-leg or foot wound. The code identifies the product rather than the clinician’s work of preparing the wound and placing the graft. The product name and ST-L variant matter because neighboring Q codes identify different AlexiGuard variants and other products.
Report Q4415 in square-centimeter units supported by the treatment record, alongside the appropriate primary application procedure. Record the product and variant, the wound site, and the area used; select the application code separately according to the treated site and area. CMS classifies Q4415 as an add-on code, so it is billed only with a primary procedure and paid within that procedure’s global period. CMS also classifies it as technical-component-only: Q4415 represents the technical portion, while a separate code covers interpretation.

Q4415 billing questions
When is Q4415 reported instead of Q4416 or Q4417?
Use Q4415 when the product record identifies AlexiGuard ST-L. Q4416 identifies AlexiGuard TL-T, and Q4417 identifies AlexiGuard DL-T.
Can Q4415 be reported without a graft application procedure?
No. CMS designates Q4415 as an add-on code that must be billed with a primary procedure; payment falls within that procedure’s global period.
How are Q4415 units determined?
The code is measured per square centimeter. Document the AlexiGuard ST-L area used and report units based on that area.
Does Q4415 include the clinician’s work of applying the graft?
Q4415 identifies the product. Select the primary application procedure separately based on the documented treatment site and area.
Does Q4415 represent a professional interpretation?
No. CMS classifies Q4415 as technical-component-only and identifies interpretation as covered by a separate code.
