About Q4184: Cellesta or Duo wound product

Reports Cellesta or Duo wound product by square centimeter when the product is supplied for application during a qualifying wound procedure.

Q4184 identifies Cellesta or Duo wound product supplied for treatment of a skin wound. Physicians, podiatrists, and other qualified clinicians may use it in office-based or outpatient wound care when applying a wound product as part of a primary procedure. The code represents the product quantity, not the clinical application service itself.

Report Q4184 only with a primary procedure; CMS treats it as an add-on and pays it within that procedure’s global period. Select units from the square centimeters of product represented, and document the wound site, treated area, product used, and amount applied. CMS classifies Q4184 as technical-component-only, with interpretation covered by a separate code. Its CMS relative values assign practice expense but no physician work or malpractice value.
