Hi Sarah,
Please note that the Blue Button 2.0 API is not a source of truth for Medicare eligibility. Eligibility is handled by the
HIPAA Eligibility Transaction System (HETS). However, there are several fields that we do offer which may support qualification decisions. Our upstream data provider, the Beneficiary FHIR Database, releases a data dictionary with each release. This is the best place to see all the fields supported and their definitions. The latest data dictionary can be found here:
https://github.com/CMSgov/beneficiary-fhir-data/releases/tag/2.141.0 (click the first link under ‘assets’ to download the data dictionary).
Note that there is a deceasedDateTime field, and the /coverage endpoint may give you some of the information you are looking for. We do not supply any data about if an enrollee has been issued a Medicare card. If you have additional questions feel free to email us at bluebuttonapi@
cms.hhs.govThanks,
The Blue Button 2.0 Team
