Wound care
About Q4396: Natalin wound graft, per square centimeter
Report Q4396 for each square centimeter of Natalin used with a primary graft application procedure to treat a wound.
Q4396 identifies Natalin by product and measures the material in square centimeters. A wound care clinician, podiatrist, or surgeon may use it while treating a wound in an office or facility. The code describes the Natalin material rather than the work of preparing the wound and applying it. Select it only when the treatment record identifies Natalin; a different graft product calls for its own product code.
Report the number of square centimeters of Natalin used, supported by the wound measurements, product record, and amount documented for the application. Link Q4396 to the primary procedure performed at that encounter: CMS classifies it as an add-on code billed only with a primary procedure and paid within that procedure’s global period. CMS also classifies Q4396 as technical-component-only. A separate code covers interpretation when interpretation is performed and documented; Q4396 itself represents the technical portion.
