What Q4382 covers
Advograft Dual is a skin substitute product used to cover a prepared wound bed. Wound-care clinicians, surgeons, and podiatrists may use it in outpatient wound clinics, physician offices, or hospital outpatient settings. This HCPCS line identifies the product rather than the clinician’s work applying it; the application procedure is reported separately with the appropriate procedure code for the wound site and extent.
Report Q4382 for the Advograft Dual product furnished, using the documented square-centimeter quantity. The record should identify the product and support the amount used and the wound treated. CMS classifies this as an add-on code: submit it with a primary procedure, and its payment falls within that procedure’s global period. CMS also classifies it as technical-component-only, with interpretation represented by a separate code.
