The Medicaid Analytic Extracts/Summary cross reference file allows researchers to link HRS/CMS Medicaid data to other HRS data products. This file is created in four steps:
- HRS provides Acumen 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.
- Acumen links respondents to their CMS Medicaid records using the matching information provided by HRS.
- For matched records, Acumen 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.
- As a final step, HRS replaces the sequence number with HHID and PN, creating the Medicaid Analytic Extracts/Summary cross reference file.

The data file that you receive from Acumen LLC 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.
