What Q4385 covers
Q4385 identifies the Apollo FT wound product supplied for application to a wound, with quantity measured in square centimeters. It represents the product used in skin-substitute graft treatment, not the clinician’s wound preparation or placement service. Wound-care clinicians, surgeons, podiatrists, and other practitioners who apply graft products may encounter it in outpatient wound care; the primary procedure depends on the wound location and treated area.
Report Q4385 only with a primary procedure, not as a stand-alone service. Select the associated application procedure based on wound site and area, and document the product identity, wound location and dimensions, and square centimeters applied. CMS classifies Q4385 as an add-on and includes payment within the primary procedure’s global period. CMS also identifies it as technical-component-only, with interpretation represented by a separate code.
