The Medicare Current Beneficiary Survey (MCBS) is a continuous, multipurpose survey of a nationally representative sample of the Medicare population, conducted by the Office of Enterprise Data and Analytics (OEDA) of the Centers for Medicare & Medicaid Services (CMS) through a contract with NORC at the University of Chicago. The central goals of the MCBS is to determine expenditures and sources of payment for all services used by Medicare beneficiaries, including co-payments, deductibles, and non-covered services; to ascertain all types of health insurance coverage and relate coverage to sources of payment; and to trace outcomes over time, such as changes in health status and spending down to Medicaid eligibility and the impacts of Medicare program changes on satisfaction with care and usual source of care.

The MCBS has been collecting data on Medicare beneficiaries for over 25 years and has conducted over 1 million interviews.  Beginning with the 2015 MCBS, the files have improved user documentation, user friendly file structures, and an updated Chart Book.  Note that to accommodate changes in sampling and data collection methodologies the 2014 MCBS data are not being released.  For more information, please read our CMS Blog post:  (
