CMS periodically produces SSA to FIPS CBSA to county crosswalk files. They released a CBSA to MSA to FIPS county crosswalk as well. Some CMS data files have SSA state and county codes or county name rather than FIPS state and county codes. Jean Roth processed the data files below for greater ease of use.
|Users should be aware that it appears that CMS did not update their SSA to FIPS county crosswalk to use 2010 Census definitions. It should be possible; however, to link the FIPS county codes in this file to those in Census' CBSA to FIPS County Crosswalk file to get more up to date CBSA definititions.|
This could mean that CMS made no changes to the source file and reused the same file in the next year when the underlying data had no change..
This file is a crosswalk by county from the old MSA to the New MSA (under the CBSA definitions) and includes SSA state and county as well.
