What it returns

Medicare Advantage and Part D enrollment for every contract, plan, state and county, every month since January 2020: contract and plan ID, county and FIPS code, enrollment, organization and marketing name, parent organization, organization type, plan type, plan name, and whether the plan is a special needs plan, an employer group plan or offers Part D.

Filter by state, county, FIPS, organization, parent company, contract, plan name, plan type, SNP, employer group, Part D and month range. Or group to get total enrollment by parent organization, organization, contract, plan, plan type, state, county or month for market share and growth.

Source: CMS Monthly Enrollment by Contract/Plan/State/County, rebuilt monthly. CMS masks counts of 10 or fewer, so those county-plan rows are left out and totals run slightly below CMS's national figures.

Charged per row or group returned.
