What Q4349 covers
Q4349 represents the Mantle DL Matrix product used to cover a wound. Wound care clinicians, surgeons, and podiatrists may use the matrix during a procedure in an office or facility setting. The code is measured by the product area in square centimeters, rather than by the number of wounds or the clinician’s time. It identifies the specific product; it does not describe the application service itself.
Report Q4349 only with a primary procedure, such as an appropriate skin substitute application code. Documentation should identify Mantle DL Matrix and support the square centimeters furnished for the treated wound. Medicare treats Q4349 as an add-on paid within the primary procedure’s global period. It is a technical-component-only code; a separate code covers interpretation. Do not use Q4349 to represent the clinician’s interpretation of the product or procedure.
