Enrollment in the ACA marketplace has historically -- and appropriately -- been weighted toward people in low-income households. Lower income workers are less likely to have access to affordable employer insurance. While just 17% of the U.S. population is in households with income between 100 and 200% of the Federal Poverty Level (FPL), 52% of marketplace enrollees nationally had income in that range as of the end of the Open Enrollment Period (OEP) for 2021. In the twelve states that have still refused to enact the ACA Medicaid expansion, where most adults with income below 100% FPL have no access to subsidized insurance, more than half of enrollees have incomes below 150% FPL.
The American Rescue Plan Act, passed in March 2021, boosted premium subsidies in the ACA marketplace at every income level, removed the former income cap on subsidy eligibility (400% FPL), and made silver plans with strong Cost Sharing Reduction free at incomes up to 150% FPL, as well as much cheaper than previously in the 150-200% FPL income bracket (0-2% of income instead of roughly 4-6% for a benchmark silver plan). During the emergency Special Enrollment Period that ran through half of 2021, fully 45% of enrollment in the 36 states then using the federal exchange, HealthCare.gov (where enrollment is dominated by the nonexpansion states) had income below 150% FPL. About 62% were below 200% FPL. Enrollment growth in OEP for 2021 (before the ARPA subsidy boosts were enacted) was also concentrated in nonexpansion states and heavily weighted toward low incomes in those states.
Given this history, as enrollment surged during the Open Enrollment Period for 2022, I was blithely confident that growth was concentrated at low incomes. I was wrong. Texas health insurance broker Jenny Hogue was onto something:
In my little corner of Texas, its not the 100%'ers that moved back, its the people who were getting killed with the subsidy cap pre-ARPA. A lot of conversations started with "is it true I can get a subsidy if my wife and I make more than $70K?".
