RALEIGH, N.C. — North Carolina’s largest health insurer said Tuesday it’s cutting some individual premiums for the first time in over a quarter century, but next year’s savings on subsidized “ObamaCare” coverage would have been much larger if Washington had left the law alone.

Blue Cross and Blue Shield of North Carolina said it proposed prices to state insurance regulators that could lower rates for next year’s Affordable Care Act policies by 4.1 percent on average. North Carolina has one of the country’s highest enrollment levels in ACA policies and Blue Cross has more than 475,000 customers in the plans offered in all 100 counties.

“I’m not aware of any plan of our size, almost 500,000 members, with this amount of decrease,” Chief Executive Officer Patrick Conway said.

Despite President Donald Trump’s efforts to repeal “ObamaCare,” enrollment has stabilized nationally at about 10 million people. After two years of stiff premium hikes, many insurers are making money again. There seems to be little risk of insurers fleeing HealthCare.gov in 2019 as some did in the past.

Several states may see premiums dip, but experts say the outlook is still uncertain and can vary greatly from state to state. Minnesota, which has taken steps to shore up its market, is another state expecting to benefit from lower premiums.

North Carolina’s Blue Cross had sought and received rate increases of between 13.5 percent and 32.5 percent in the four years after the first year ACA-compliant insurance plans began being sold in 2014. Blue Cross said it lost more than $450 million on the plans in the first three years; it earned a $118 million profit on “ObamaCare” policies in 2017.
