What Q4362 covers
Q4362 represents the Cygnus disk product supplied for wound coverage, measured by the area of product reported in square centimeters. It is a product-supply code, not the clinician’s application service. Wound-care physicians and other qualified practitioners may use the product in outpatient wound clinics or hospital settings as part of treatment for a wound requiring a biologic covering.
Report Q4362 only with the applicable primary procedure; CMS treats it as an add-on and pays it within that procedure’s global period. Select the primary application procedure according to the wound’s location and the applicable procedure rules, and document the product used and the quantity supplied. CMS identifies Q4362 as technical-component-only: it represents the technical portion, while a separate code covers interpretation. The application service and product supply are distinct reporting elements.
