What Q4317 covers
Q4317 identifies Vitograft, a skin substitute product supplied for wound treatment, with reporting based on square centimeters. It may be used during treatment of wounds such as chronic diabetic foot or venous leg ulcers. A physician or other qualified clinician typically applies the product as part of a wound procedure in an office or outpatient setting.
Report the product quantity in square centimeters and document the product used, the wound area treated, and the related primary procedure. CMS classifies Q4317 as an add-on code: bill it only with a primary procedure, and its payment is within that procedure’s global period. CMS also identifies it as technical-component-only; a separate code covers interpretation.

Is interpretation included in Q4317?
No. CMS classifies Q4317 as technical-component-only; a separate code covers interpretation.
