Issuer Level Enrollment Data
The Centers for Medicare & Medicaid Services (CMS) Center for Consumer Information and Insurance Oversight (CCIIO) is committed to increasing transparency in the Health Insurance Marketplace. CMS has released issuer level enrollment data for the Federally-facilitated Marketplace (FFM). This is data on issuer enrollment patterns. It includes a cumulative total of consumer plan selections, organized by issuer, during the calendar year indicated below through the FFMs, including FFMs where States perform plan management functions, and State-based Marketplaces (SBM) on the Federal Platform (SBM-FPs). The data is further divided at the county level and in a separate dataset (within the same file) that divides that data at the plan level. The data also includes characteristics of enrollees such as sex, age, income, and tobacco use by issuer. The enrollment data were pulled from CMS’ MIDAS data system.
