ANCHORAGE  — A health insurer is asking state regulators for a second large rate increase for its Affordable Care Act plans.

Alaska Public Radio Network reports Premera Alaska is seeking a 39 percent hike for 2016 from regulators. Last year’s increase was 37 percent.

Premera has about 8,000 members of its heath care act plans in Alaska. It says a small number had complex medical problems and filed millions of dollars in claims last year.

Many Premera members will qualify for subsidies which would reduce the impact of any increase.

Another insurer, Moda Health, is seeking an increase of about 22 percent.

The state will decide by Aug. 25.
