Contract/Plan/State/County Package

The January 2025 enrollment data may not reflect all of the enrollments processed during the Medicare Open Enrollment period since these data reflect enrollments processed through December 6, 2024.  

Updated in Jan, 2021, add plans that terminated on 12/31/YYYY, including 202012 file.
CPSC_enrollment_YYYY_MM.zip
The State/County/Contract/Plan (CPSC) Enrollment Data package is a compressed file (using SecureZIP) 
consisting of the following files:

Read_Me_CPSC_Enrollment_YYYY.txt - this file
CPSC_Contract_Info_YYYY_MM.csv - data file (where YYYY = year and MM = month)
CPSC_Enrollment_Info_YYYY_MM.csv - data file (where YYYY = year and MM = month)

The CPSC_Contract_Info_YYYY_MM.csv file is a comma separated value (csv) text file
containing descriptive attributes for every contract/plan combination that appears
in the CPSC_Enrollment_Info_YYYY_MM.csv file.

The CPSC_Enrollment_YYYY_MM.csv file is a comma separated value (csv) text file 
contains the enrollment data for the month and year described in the file name for
every contract/plan in every state/county.

Text values in the data files are surrounded by double a quote (") so that commas that 
are part of an organization name could be included. The data type of each column is 
shown in brackets ([]) below. The columns in each data file are described below, the
column names are included as the first row of data:

Special Notes:

  (1) The privacy laws of HIPAA have been interpreted to prohibit publishing 
  enrollment data with values of 10 or less. Consequently, some enrollment data
  in this file have been set to blank because the enrollment was 10 or less. 

  (2) The enrollment data file contains more than 65,536 rows of data. This means 
  that older versions of Microsoft Excel will not be able to import all of the data 
  for viewing. All of the data can be viewed in Microsoft Access or in a statistical 
  package, such as SAS. 
 
  (3) The enrollment data file lists enrollees by their legal state and county of 
  residence; this is the county used for payment purposes. For example, an individual 
  who moved from Baltimore to Los Angeles and enrolled in XYZ Insurance company of 
  California would be paid at the Baltimore rate until the change of address was 
  recorded in the Social Security system. Consequently, the XYZ enrollment records 
  will include both the California counties in its approved contract service area as 
  well as the counties throughout the United States where XYZ has enrollees. 

  Please note that enrollment in these out of service area counties is very often under
  10, which leads to the suppression of the numbers.  This file does not indicate which 
  counties belong to the approved contract service area of a Medicare Advantage 
  organization and which counties are outside of its service area. You may refer to 
  the Medicare Advantage county service area file, which is available as a separate 
  download, to identify the approved contract service areas for these organizations.
