Medicare Supplement insurance in Oregon is a policy that helps to fill the gaps that Original Medicare (Part A and Part B) cannot. There are ten Medicare Supplement plans available to choose from.

  • Of the ten plans offered, Cigna offers the best Medicare Supplement Plan G rates in Oregon, with a monthly rate of $149 per month for the most comprehensive coverage.
  • We also found Cigna offers the best Medicare Supplement Plan N pricing at $106 per month. This plan has the best value for beneficiaries who don’t mind trading certain benefits for lower monthly premiums.
  • For those wanting the lowest possible monthly premium, Mutual of Omaha’s High Deductible Medigap Plan G is considerably cheaper at $47 per month for the same benefits as Medicare Plan G. Beneficiaries must pay the annual $2,700 deductible before coverage.

Below are highlighted features and benefits of each plan.

When Can I Apply for a Medicare Supplement Plan?

The best time to enroll in a Medigap plan in Oregon will be within your six-month Medigap Open Enrollment Period (OEP). During this time, pricing and plan options from a Medicare insurance company will be better and equal for every beneficiary. See below for age specifics.

Age 65 or older: Your enrollment period begins when you have Part B coverage. It can't be changed or repeated.

Turning 65: Enrollment begins the first month that you are 65, and again, enrollment in Part B will be needed.

Under 65: If you have a qualifying disease or ESRD (end-stage renal disease), insurance companies are required to offer at least one kind of Medigap plan. This will only be available to you if you are enrolled in Part B, and may cost you more overall.

You will receive guaranteed issue rights when enrolling during your OEP, which means that you cannot be denied coverage or charged more by insurance companies. The Medicare insurance company cannot consider your current health or pre-existing conditions when determining your Medigap rates, and you are guaranteed enrollment in the plan of your choice.

There are a few other instances where you may have guaranteed rights such as losing group coverage, moving out of a plan's service area, or your insurance provider going out of business. If you fall into one of these categories, you may be eligible for a Special Enrollment Period.

Oregon Birthday Rule

In Oregon, you will have the chance to change your plan annually with the birthday rule. This rule allows you to switch to any carrier or plan of equal or lesser benefit without being subject to denial or medical underwriting and pricing. For instance, you can switch from Plan G to Plan N with any carrier, and Plan G with one carrier to Plan G with another, but you cannot switch from Plan G to Plan F, because Plan F has a higher value than Plan G. This period starts on your birthday each year and lasts for 30 days, giving you 31 days total to make the plan switch.
