Oregon Health & Science University’s hospital in southeast Portland. New rate proposals from Oregon financial regulators could result in double-digit premium increases for Oregonians' health insurance next year. The Oregon Division of Financial Regulation announced last week that it had reviewed recent rate hike proposals from major health insurance companies and decided on an average 16% increase in costs to individual consumers on the Oregon Health Insurance Marketplace. “Increasing insurance rates are part of the rising cost of living felt by many Oregonians,” said Oregon Insurance Commissioner TK Keen in a statement. The increased rate proposals come as Oregon has taken action on the federal level to push back on rising health insurance costs.
