MIDUS-CMS (Centers for Medicare & Medicaid Services) linked Data

MIDUS-CMS linked data have been generated for MIDUS participants who: (1) completed the MIDUS 1 (M1) survey or MIDUS Milwaukee African-American oversample (MKE1) survey; (2) were eligible for or enrolled in Medicare and/or Medicaid; and (3) were identified as deceased as of May 2022. Note that future MIDUS-CMS releases will be updated with an expanded sample of living Medicare and/or Medicaid beneficiaries who provide informed consent for linking to their Medicare/Medicaid information. These data will be available on a secure virtual environment managed by the NIA Data LINKAGE Program: NIA Data LINKAGE Program (LINKAGE) | National Institute on Aging (nih.gov)

MIDUS-CMS linked data consists of Medicare and/or Medicaid information of the MIDUS participants described above. Specifically, the linked data contain Medicare Part A & B, Medicare Part C (Medicare Advantage), Medicare Part D, Medicare-Managed Assessments, and Medicaid (if applicable).
