Illinois: Preliminary avg. 2022 #ACA rate changes (unweighted): +5.1% indy mkt; +3.5% sm. group
Unfortuantely, Illinois is another state which doesn't make it easy to analyze annual health insurance premium rate filings. There's no details on their insurance department website, their SERFF listings don't seem to include the actuarial memos or URRT forms, and even the federal Rate Review listings only include the average requested rate changes; the actuarial memos there are mostly heavily redacted.
The unweighted average rate changes requested for 2022 come in at +5.1% for the individual market and +3.5% for small group plans. It's worth noting that neither of the UnitedHealthcare listings from 2021 (on the small group market) show up in the federal database, which either means they're pulling out of the Illinois market entirely or they just haven't been added to the listings yet. Given that it's mid-October, the former seems more likely.
