What is a Medicaid Provider Number?

Putting it simply, Medicaid Provider Number (MPN) is generally a 6-digit verification number that verifies the authenticity of Medicare providers. It verifies that a specific provider is genuine in providing Medicare services for a specific speciality. The 6-digit code is not just random digits assigned against each verified Medicare provider, it has a meaning of its own.

The first two digits represent the state where the provider is located. And the last 4 digits specify the type of facility that the provider serves in. For Ambulatory Surgery Centers, the MPN is a 10 digit number.

Here, the first two digits represent the state where the center is located and the rest 8 represent the type of facility provided.

It is also popularly known by some other names like OSCAR (Online Survey, Certification, and Reporting) Number, Provider Number, and Medicare Identification Number (MIN). Not to be confused, all these names represent the one number only.

Importance of Medicaid Provider Number (MPN) in Healthcare

CMS issues an MPN to be used by Medicare for surveys, certifications, and assessments of patients. An MPN is obtained after passing a survey or inspection by Medicare.

An MPN will not be provided to providers who are not involved in Medicare. Hence, it is mandatory for providers to participate in Medicare.

As mentioned above, besides MPNs, another name for them is OSCAR numbers (Online Survey, Certification, and Reporting).

While not the primary identification method for Medicare and Medicaid providers anymore, the MPN once served as the primary identifier. The Medicare Provider Number (MPN) was officially renamed to the CMS Certification Number (CCN) by CMS on April 20, 2007; at that time, the National Provider Identifier (NPI) became the new primary identification standard for Medicare/Medicaid providers.

Providers continue to receive the MPN (or CCN), however, to verify their Medicare/Medicaid certifications, surveys, and patient assessments.
