Medicare Current Beneficiary Survey

In June 2025, CMS released the MCBS – Overview Infographic, providing a quick reference guide on the Medicare Current Beneficiary Survey (MCBS). Conducted by NORC at the University of Chicago, this ongoing study aims to gather valuable information from Medicare beneficiaries.

Note that beneficiaries may be contacted by NORC on behalf of CMS, which is an exception to usual guidelines. For further details, and to verify the study and the interviewer, refer to the following:

1. For more information, visit the MCBS Respondent page at https://mcbs.norc.org/
2. Confirm the letters you received match those posted at Medicare.gov, the MCBS Selection Letter
