What Q4371 covers
Q4371 identifies the Neoguard wound-care product by the square centimeter. It represents the product supply, not the clinical work of preparing the wound or applying the material. Wound-care clinicians and surgeons may use it during treatment of a wound when Neoguard is the product selected. The amount is tied to the product used, while the associated application service is represented by a separate primary procedure code.
Report Q4371 only with a primary procedure, and only for the documented Neoguard product and area supplied. The primary application code is selected for the applicable site and wound area; documentation should identify Neoguard and support the square-centimeter quantity. CMS treats Q4371 as an add-on paid within the primary procedure’s global period. It is also classified as technical-component-only, with interpretation covered by a separate code.
