Back in March 2020, you may have read here that the emergency supplemental unemployment insurance provided by the CARES Act -- $600 per week for up to 4 months -- would likely lift some uninsured people in states that had refused to expand Medicaid out of the so-called "coverage gap." That is, the extra UI income would raise some low income people over the income threshold for marketplace subsidy eligibility in nonexpansion states: 100% of the Federal Poverty Level (FPL).
Back in December, you may have read here that as of the end of Open Enrollment for 2021, marketplace enrollment was indeed up 10% over 2020 levels in nonexpansion states, but flat in expansion states.
This month, you may have read here that takeup of marketplace coverage at incomes just over the subsidy eligibility threshold in nonexpansion states -- 100-138% FPL -- has historically been weak -- under 50% in of these states states.
More detailed data about 2021 enrollment was released by CMS on April 21. I don't think it's an exaggeration to say that enrollment at the lowest subsidy-eligible income levels in nonexpansion states exploded this year.
