The American Rescue Plan enacted last month radically though temporarily boosted premiums in the ACA marketplace. The premium paid by enrollees for the benchmark (second cheapest) silver plan is now set at $0 for enrollees with household incomes up to 150% of the Federal Poverty Level, and at 0-2% of income for enrollees with incomes in the 150-200% FPL range. That tops out at $43 per month for a single person with an income of $25,520.
Bronze plans are now available at zero premium to almost any enrollee with an income below 200% FPL (and to a fair number at higher incomes). But bronze plan deductibles average $6,921. At incomes up to 200% FPL, silver plans come with strong Cost Sharing Reduction (CSR), which brings deductibles down to an average of $177 for enrollees with incomes up to 150% FPL and $800 in the 150-200% FPL range. The contrast is similarly dramatic in annual out-of-pocket maximums, which usually top $8,000 in bronze plans. CSR brings them down to an average of $1189 at incomes up to 150% FPL and $2529 at 150-200% FPL.
Prior to the subsidy boost, increasing numbers of enrollees with incomes below 200% FPL were selecting bronze plans, especially in the 150-200% FPL range, where benchmark silver topped out at $135/month for an individual (see The darker side of free bronze). The newly enhanced subsidies should reverse that trend. Still, even modest premiums are often experienced as steep at low incomes, and zero-premium plans remove administrative friction that deters some enrollees (arranging and executing on monthly premium payment can be surprisingly difficult).
