  • These rate increases are averages; your particular increase could be different. If your company increases rates with age, you may have a separate rate increase when you enter a new age category.
  • If you see a company that has more than one rate increase in a year, it is likely that it took over another company's business.
  • The Division of Financial Regulation does not regulate Medicare Advantage plans or rates.


  • If you have questions about your particular rate increase, call your insurance company.
  • If you have questions about how Medicare works or your insurance choices, call the Senior Health Insurance Benefits Assistance (SHIBA) program: 800-722-4134 (toll-free). SHIBA also publishes an annual guide of Medicare insurance plans sold in Oregon. You can find this on the SHIBA website.
