HCPCS code Q4372: AmchoPlast EXCL, per square centimeter2026 Medicare rate & RVUs

Medicare pays $127.26 for Q4372 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 Q4372 covers

Q4372 identifies the AmchoPlast EXCL product supplied for use as a biologic wound-covering matrix. It represents the product, not the clinician’s work applying it. Wound-care clinicians may use the material during a procedure for a selected wound; the code is reported by the square centimeter of product represented. The exact product name matters because nearby HCPCS codes identify other tissue products or AmchoPlast variants.

Report Q4372 only with a primary procedure, not by itself. CMS treats it as an add-on paid within the primary procedure’s global period. Documentation should identify AmchoPlast EXCL, the associated wound procedure, and the product quantity in square centimeters. CMS classifies the code as technical-component-only; a separate code covers interpretation. The clinical application service is represented by the primary procedure, while Q4372 identifies the product. Do not substitute another product’s HCPCS code based only on wound size or site.
