When to Enroll


You have six months to enroll in a MedicareBlue Supplement plan, starting on the first day of the month your Medicare Part B coverage begins. (This could be the month you turn 65 or later. It depends when you enrolled in Part B and when you specified for your coverage to begin. )

With the exception of Plan A, which is always available, you can enroll after the six-month Open Enrollment Period, but you may need to provide detailed health information and may be denied coverage.


You can enroll in a prescription drug plan beginning  three months before the month of your 65th birthday, the month of your birthday, and the three months that follow. This is considered the Initial Enrollment Period. If you are disabled, you can enroll any time after receiving disability benefits for 24 months.

If you currently have Medicare, you can enroll (or make plan changes) during the Annual Enrollment Period, between Oct. 15 and Dec. 7 each year.

What You Need

To enroll in a MedicareBlue Supplement plan and/or a MedicareBlue Rx drug plan, you must:

  • Be eligible for Medicare Part A (In other words, you're at least 65 and eligible for Social Security, or you're under 65 and have received disability for two years.)
  • Be enrolled in Part B
  • Live in the plan's service area
  • Continue to pay your Part A and B premiums

For MedicareBlue Supplement plans, you likely don't need to have a physical exam or provide health history. But you may if you don't enroll during the six-month open enrollment period.
You also need to think about plan options and pick the one that's right for you.

Once you meet the requirements, you can apply for a MedicareBlue Supplement or MedicareBlue Rx plan. Enrollment is simple and can be completed entirely online.

Special Enrollment Period for MedicareBlue Rx

There are life events and situations that may allow you to enroll in a MedicareBlue Rx plan after an Initial or Annual Enrollment Period has ended. You may qualify if:

  • You’re eligible for financial help from Social Security or your state
  • You move outside your existing plan’s service area
  • Your existing plan’s government contract ends, or the plan goes out of business
  • You lose prescription drug coverage from an employer or union, or your drug coverage is no longer as good as the standard Part D benefit
  • You find a plan in your area that has achieved Medicare's five-star plan rating for the year you would like to make a change. You can switch any time during that year.

You may also qualify for other reasons. If you have an enrollment question, simply call your Wellmark representative. We're happy to help.
