Variable: ENRL_SRC
Enrollment Source
Description
This variable indicates the source of enrollment data.
Comment
The Centers for Medicare & Medicaid Services (CMS) has updated the Medicare enrollment source data for the Master Beneficiary Summary File (MBSF). As of March 2017, the MBSF includes Medicare enrollment information from the CMS Common Medicare Environment (CME) rather than the CMS Common Medicare Environment (CME). Data from the two sources was nearly identical. The CME improves the identification of Medicare Part B enrollment and also allows for more timely release of the MBSF. The universe of beneficiaries in the CME versus the EDB version of the MBSF are only slightly different.
