The Medicare Claims and Summary cross reference file allows researchers to link HRS/CMS Medicare 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 Medicare retrieval. This list is keyed on a sequence number created by HRS.
- Acumen links respondents to their CMS Medicare 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.
- As a final step, HRS replaces the sequence number with HHID and PN, creating the Medicare Claims and Summary cross reference file.
