(Portland, OR) -- Healthcare deductibles and copays are on the rise for Oregonians. The Oregon Health Authority reports that between 2015 and 2022 the costs of deductibles and copays increased 17 percent. That doesn't include increases in premiums. In 2022, Oregonians with commercial health insurance paid 13 percent of their total health care costs, while people with Medicare Advantage paid nine percent. At least 28 percent of Oregonians were considered underinsured in 2021, meaning that even though they had health insurance, it was too expensive for them to use.
