HCPCS Q4326: Wound productMedicare rate & RVUs

Medicare pays $127.26 for Q4326 nationally in the office. Local office rates run $109.31–$183.51.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What Q4326 covers

Q4326 identifies WoundPlus supplied for wound coverage during a wound-care procedure. It represents the product, not the clinician’s work applying it. Wound specialists, podiatrists, surgeons, and other clinicians may use wound coverage products when treating ulcers or other wounds in outpatient settings. The specific product and the amount used should be identifiable in the record and supported by the product documentation.

Report the quantity in square centimeters and pair Q4326 with the primary procedure for the wound service; the application procedure is reported separately. CMS classifies Q4326 as an add-on, with payment within the primary procedure’s global period. CMS also identifies it as technical-component-only, with interpretation covered by a separate code. Documentation should connect the WoundPlus product to the treated wound and state the quantity used. The product code does not replace the code describing the application service.
