The Medicaid Analytic Extracts (MAX) and TMSIS Analytic Files (TAF) 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:
- 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.
- LINKAGE links respondents to their CMS Medicaid records using the matching information provided by HRS.
- 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.
- As a final step, HRS replaces the sequence number with HHID and PN, creating the Medicaid Analytic Extracts (MAX) and TMSIS Analytic Files (TAF) cross-reference file.

Notes:
The data file that you receive 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_26. In order to merge CMS Medicaid records with HRS files, you need to replace the BID_HRS_26 identifier with HHID and PN using this cross-reference file.
