About Q4224: HHF10-P wound matrix per area
Q4224 represents HHF10-P by square-centimeter quantity when the product is used with a primary wound-treatment procedure.
Q4224 identifies HHF10-P, a wound-care tissue product reported by square-centimeter quantity. It represents the product used during wound treatment, rather than the clinician’s work to prepare or apply it. Wound-care clinicians and surgeons may use the product in outpatient or facility settings when treating a wound and performing a separately coded primary procedure.
Report Q4224 with the applicable primary procedure, not by itself; CMS treats it as an add-on code paid within that procedure’s global period. Record the product and the square-centimeter quantity used, along with the wound site and the associated procedure. CMS classifies Q4224 as technical-component-only, with interpretation covered by a separate code. The primary procedure code describes the wound treatment; Q4224 identifies the HHF10-P product quantity.
