The state's individual health insurance market got even smaller last year, according to a new state report, but the annual rate of decline slowed significantly.
The figures are another hint of relative stability in a market that has undergone big changes with the federal Affordable Care Act (ACA), including a period of premium spikes and plummeting enrollment followed by rate declines the past two years.
The report issued this month by the state Commerce Department said that 141,110 people bought individual policies during 2018, down from about 300,000 people during 2015.
"We want the market to be stable for consumers, for the carriers," said Grace Arnold, the deputy commissioner of insurance at Commerce, in an interview. The latest numbers make state officials "cautiously optimistic that we're turning the corner on instability and getting into a more stable market."
The report comes a few weeks before state insurance regulators are scheduled to release, on July 9, requested rate changes from health insurers for 2020. Final rates will be released in early October.
The ACA brought sweeping changes beginning in 2014 to the market where individuals buy health insurance. The market is a key source of coverage for people under age 65 who are self-employed and those who don't get health plan benefits from their employer.
The federal health law made it illegal for health insurers to deny coverage to people based on pre-existing health problems. It also created government-run health exchanges like MNsure in Minnesota where people could shop for coverage and qualify for tax credits that lower premium costs.
Insurers guessed wrong, however, in setting rates for 2014 and 2015 and racked up big losses as claims outpaced premiums. The dynamic between premium revenue and claims expense is expressed in terms of the "medical loss ratio," or MLR. Every year in June, Commerce publishes a report on the ratio in Minnesota.
