About Q4187: Epicord wound covering product
Reports Epicord wound-covering product by square centimeter when it is applied during a separately coded wound procedure.
Q4187 represents Epicord, an amniotic membrane product used as a covering for prepared wounds. Wound-care clinicians may apply it in outpatient settings to chronic wounds such as diabetic foot ulcers or venous leg ulcers. The code identifies the product, not the clinician’s wound preparation or application service.
Report the number of square centimeters of Epicord represented by the units, and pair the product code with the primary procedure for its application. Documentation should identify Epicord, the treated wound and site, the product area used, and the application procedure. CMS classifies Q4187 as an add-on code: it is billed only with a primary procedure and paid within that procedure’s global period. CMS also classifies it as technical-component-only; a separate code covers interpretation.

Which application code should accompany Q4187?

No. CMS classifies Q4187 as technical-component-only; a separate code covers interpretation.
