The Oregon insurance commissioner, Laura N. Cali, has just approved 2016 rate increases for companies that cover more than 220,000 people. Moda Health Plan, which has the largest enrollment in the state, received a 25 percent increase, and the second-largest plan, LifeWise, received a 33 percent increase.

Jesse Ellis O’Brien, a health advocate at the Oregon State Public Interest Research Group, said: “Rate increases will be bigger in 2016 than they have been for years and years and will have a profound effect on consumers here. Some may start wondering if insurance is affordable or if it’s worth the money.”

President Obama, on a trip to Tennessee this week, said that consumers should put pressure on state insurance regulators to scrutinize the proposed rate increases. If commissioners do their job and actively review rates, he said, “my expectation is that they’ll come in significantly lower than what’s being requested.”
