HRS Medicaid Analytic Extracts (MAX) and Summary Files Cross-Reference

The Medicaid Analytic Extracts/Summary cross reference file allows researchers to link HRS/CMS Medicaid data created by the NIA Data LINKAGE Program (LINKAGE) to other HRS data products. This file is created in four steps:

  1. HRS provides LINKAGE with a file of respondents (and matching information) who meet criteria for Medicaid retrieval. This list is keyed on a sequence number created by HRS.
  2. LINKAGE links respondents to their CMS Medicaid records using the matching information provided by HRS.
  3. For matched records, LINKAGE replaces the respondent's indentifiers with a unique identifier (BID), links that value to the HRS sequence number, and provides HRS with a sequence number to BID cross-reference file. Please note that the BID used here is NOT the same as the BID used to merge the Medicare Claims and Summary cross reference.
  4. As a final step, HRS replaces the sequence number with HHID and PN, creating the Medicaid Analytic Extracts/Summary cross reference file.

Documentation and Links

The data file that you from LINKAGE is keyed on a unique 10-character field that replaces the respondent's identifying information. The name of this field is BID_HRS_23. In order to merge CMS Medicaid records with HRS files, you need to replace the BID_HRS_23 identifier with HHID and PN using this cross-reference file.
