Sources & Notes

Source: Centers for Medicare and Medicaid Services, Marketplace Open Enrollment Period Public Use Files.

Notes: United States totals include the 50 states and DC. N/A specifies not reported. Includes data for the 2017,  2018,  2019, and 2020 Open Enrollment periods on plan selections that include cost-sharing reductions (CSRs) or advance payment tax credits (APTCs). Due to some unreported state data, U.S. totals may be underestimated. Caution should be used when making comparisons between states and across years, as some states use and some use their own platform (which can also change). Eligibility for financial assistance is determined on the application; however, not all consumers eligible for APTCs or CSRs actually receive such financial assistance. Consumers who are APTC-eligible can elect not to use all or part of their APTC, and instead claim their full premium tax credit when filing taxes. Consumers eligible for CSRs generally need to select a silver plan in order to receive these CSRs. This file counts consumers as receiving financial assistance when the APTC amount applied to their plan selection is greater than $0 or the plan selection includes CSRs. More information about APTC and CSRs is available at
