HCPCS Q4126: Wound matrixMedicare rate & RVUs

Medicare pays $127.26 for Q4126 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 Q4126 covers

Q4126 identifies the supply of Memoderm, DermaTranZ, or InteguP, products in the skin-substitute and wound-matrix category. It is associated with wound-care procedures in which a clinician places the selected material over a prepared wound bed. Wound-care physicians, surgeons, and other clinicians who treat wounds may furnish it in office or hospital settings. The code represents the named product, not a general wound assessment or the clinician’s application work.

Report Q4126 only when one of these products was supplied, and document the product, wound site, amount used, and related primary procedure. CMS identifies it as an add-on code: it must be billed with a primary procedure and is paid within that procedure’s global period. CMS also classifies it as technical-component-only, with interpretation covered by a separate code. Do not report Q4126 for another matrix merely because it serves a similar wound-care purpose.

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor.
