Description of Medicaid Enrollees

Date Recorded

This video is one segment in a series of videos from ResDAC’s Introduction to the Use of the Medicaid and CHIP TAF (T-MSIS Analytic File) Data for Research.

Topics include:

Million Hearts® Cardiovascular Disease Risk Reduction (Million Hearts®) Model Alignment Files

The eleven model alignment files contain the point-in-time eligibility and alignment status of model beneficiaries, and a list of eligible-but-not-enrolled patients for participating practice reporting. These alignment validation files, also known as Enrollment, Validation, Alignment, and Adjudication (EVAA) files, were generated semi-annually throughout the duration of the model, each October and April. There were a total of 10 EVAA analytical cycles, between October 2017 and April 2022. The model alignment file names indicate the cycle number (01-10) and the year and month of the cycle. In addition, there is a final model alignment file that represents the alignment status of model beneficiaries at the end of the model.

What does this file include? (variable highlights)

  • Model-Assigned Practice ID
  • Practice Name
  • Practice TIN
  • Unique Model-Assigned Patient ID
  • Aligned Flag
  • Eligible Flag
  • Patient Status Change Reason Code

A record represents the eligibility and alignment status of a beneficiary.

The Unique Model-Assigned Patient ID can be used to link to other Million Hearts® beneficiary files (demographic, visit, and alignment), but cannot link to other CCW non-Million Hearts® files.

The Model-Assigned Practice ID can be used to link all Million Hearts® data files for provider-oriented analytics. It does not link to other CCW provider data.
