Back in mid-October, I devoted a handful of posts (1, 2, 3) to New Mexico's great ACA marketplace experiment: instructing insurers to price silver plans as platinum-value in 2022 -- that is, as if no one with an income over 200% FPL would buy a silver plan. Below that income threshold, silver plans, enhanced by strong Cost Sharing Reduction (CSR), actually are platinum-equivalent, having an actuarial value of 94% (at incomes up to 150% FPL) or 87% at 150-200% FPL). The instructions were adhered to: throughout the state gold plans offered for 2022 were priced well below the benchmark silver plan.
The results were largely as planned, and can fairly be deemed a success. At incomes over 200% FPL, two thirds of enrollees chose gold plans, compared to 35% last year. At incomes in the 138-200% FPL range, comprising most enrollees eligible for strong CSR, 65% of enrollees chose silver plans -- and just 4% chose bronze, generally a bad choice for low income people, with single-person deductibles averaging about $7,000. Among all enrollees, 57% chose gold plans.
Enrollment was up modestly, from 42,984 in Open Enrollment 2021 to 45,973 this year, a 7% increase. That's below the 11.5% average increase this year for states that have expanded Medicaid, as New Mexico has. But New Mexico launched a new state-based exchange, bewellnm, in the Open Enrollment Period for 2022, and that transition has often triggered enrollment losses for other states.
Here are the metal level choices broken out by income (courtesy of bewellnm, at the first link above):
