What Q4409 covers
Q4409 identifies the Amniomatrix F3X wound product supplied for use in wound coverage, with the reported quantity measured in square centimeters. It represents the product, not the clinician’s work to prepare or apply it. Wound care clinicians may use this type of product during treatment of wounds such as diabetic foot or venous leg ulcers when the product is selected for the patient’s wound. The clinical record should identify the product and the amount furnished.
Report Q4409 only with a primary procedure; CMS treats it as an add-on code and pays it within that procedure’s global period. Select the primary application service based on the wound site and procedure performed, and report product units supported by the documented square-centimeter quantity. CMS classifies Q4409 as technical-component-only, with interpretation covered by a separate code. Its CMS valuation has no physician work component; the reported service is the product supply.
