Where can I find a list of modifiers paid by Medicare?
We do not publish a comprehensive list of modifiers payable by Medicare. However, the modifiers are listed in the Current Procedural Terminology (CPT) coding handbook and in the HealthCare Procedure Coding System (HCPCS) book. The American Medical Association’s CPT handbook includes a list of most modifiers and provides a detailed description of Level I (1) modifiers (composed of two numbers). The HCPCS handbook provides a comprehensive list of Level II (2) modifiers (composed of either two alphas or an alpha and a number). Also, the Centers for Medicare & Medicaid Services (CMS) online Medicare Claims Processing Manual and the Medicare Benefit Policy Manual gives instructions for the using the appropriate modifier with specific services. Please refer to the CMS web site at http://www.cms.hhs.gov/Manuals/IOM/list.asp, for more information.
