HCPCS code Q4194: Wound product2026 Medicare rate & RVUs

Medicare pays $127.26 for Q4194 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 Q4194 covers

Q4194 identifies Novachor wound product in one-square-centimeter units. It represents the product used to cover a wound, rather than the clinician’s application work. Wound-care physicians, podiatrists, and surgeons may use skin-substitute products during treatment of wounds such as diabetic foot ulcers or venous leg ulcers. Report this code with the applicable primary procedure for the product application, not as a stand-alone wound service.

Count units from the documented square centimeters of Novachor furnished for the service. The record should identify the product, its quantity, the treated wound, and the associated application procedure. CMS treats Q4194 as an add-on: it must be billed with a primary procedure and is paid within that procedure’s global period. CMS also classifies the code as technical-component-only, with interpretation covered by a separate code.
