We have had plenty of time to celebrate the 21% surge in ACA marketplace enrollment, most likely triggered primarily by the major boosts to premium subsidies provided last March by the American Rescue Plan Act (ARPA). Now, with CMS's Public Use Files tracking marketplace enrollment for 2022 released on the ACA's 12th anniversary, it's time for some disappointment.
In the 33 HealthCare.gov states, for which CMS provides detailed plan selection breakouts, the ARPA subsidy boosts did not reduce underinsurance as much as might have been expected during the Open Enrollment Period (OEP) for 2022. That is, silver plan selection at low incomes (up to 200% FPL), where Cost Sharing Reduction (CSR) makes silver plans far and away the best value for almost all enrollees, modestly reversed a four-year slide, but not nearly as much as might have been expected.
In HealthCare.gov states this year, 60% of enrollees had incomes below 200% FPL, and 80% of them selected silver plans.
