What is a Medicare Provider Number (MPN)?

A Medicare/Medicaid Provider Number (MPN) verifies that a provider has been Medicare certified and establishes the type of care the provider can perform. This identifier is a six-digit number. The first two digits specify the state in which the provider is located, and the last four digits indicate the type of facility. For Ambulatory Surgery Centers, the MPN is 10 digits — with the first two digits representing the state where the surgery center is located.

MPN is also known as an OSCAR (Online Survey, Certification and Reporting) Number, Medicare Identification Number, and Provider Number.

Why are MPNs an important metric for healthcare?

An MPN is issued by CMS and used by Medicare for surveys, certification, and patient assessments. A facility must pass a Medicare survey/inspection to obtain an MPN. Providers that do not participate in the Medicare program will not have an MPN.

MPN is also known as an OSCAR (Online Survey, Certification and Reporting) Number, Medicare Identification Number, and Provider Number.

Though no longer the primary identification method, the MPN was once the primary identifier for Medicare and Medicaid providers. MPN was officially renamed to CMS Certification Number (CCN) by CMS on April 20, 2007 and, at this time, the National Provider Identifier (NPI) became the new primary identification standard for Medicare/Medicaid providers.

The MPN (or CCN), however, continues to be issued to providers to confirm Medicare/Medicaid certification for certifications, surveys, and patient assessments.
