What Q4360 covers
AmchoPlast FD is a dehydrated amniotic membrane product supplied for placement as a biologic covering during wound reconstruction. A clinician may use it in treating a cutaneous wound, such as a chronic ulcer or surgical wound. Surgeons and wound-care clinicians apply the product after preparing the wound bed as part of a separately coded graft-application procedure. Q4360 represents the product, rather than the clinician’s wound evaluation or the application work.
Report the product by square centimeter with the primary application procedure; choose that procedure according to the treated site and area. Documentation should identify AmchoPlast FD, the wound site and dimensions, the product area used, and the application procedure. CMS classifies Q4360 as an add-on code, so it is billed only with a primary procedure and paid within that procedure’s global period. It is also a technical-component-only code; a separate code covers interpretation.
