Provider of Services Files -- SAS, Stata, CSV
Provider of Services Data Centers for Medicare & Medicaid Services has information about Medicare approved providers.
Clinical Laboratory Improvement Act (CLIA) labs were separated from the other providers into their own file beginning in 1997.
Provider of service data is collected from CMS Form 1539 plus Medicare/Medicaid applications for certification:
The naming covention changed to mnemonic names from PROVNNNN-type names in 2011. A crosswalk for select variables is available.
The Provider of Service file includes provider ZIP Code. A ZIP Code distance database is also available.
The provider category code variable
lists the categories of providers or suppliers from 1991-on that are included in the provider of service file.
Some Hospitals ( provider category = "01" ) have an "E" or "F" in position 6 of the provider number. The "E" indicates a Non-federal emergency hospital. The "F" indicates a Federal emergency hospital. See 2779E on page 13 of R29SOMA.pdf. These hospitals are non-participating hospitals where participting is defined in part of Title XVIII in 1866.
The Provider of Services file is a historic file, so only a recent file might be needed.
