When Can I Apply for a Medicare Supplement Plan?

If You are 65 or Older

The best time to enroll is during the Medigap Open Enrollment Period. The Medigap Open Enrollment Period in Maryland starts the first month you are 65 or older and have started your Part B coverage. This period lasts six months, and it cannot be changed or repeated. When you apply during the Open Enrollment Period, medical underwriting cannot be used to determine policy approval, limitations, or pricing. If you try to apply after this window closes, your application can be declined, and if it is approved, you may be charged a higher premium. An exception is made for people with guaranteed issue rights.

If You are Younger than 65

You will likely not be able to purchase a Medigap policy if you are under 65, unless you have a qualifying disability or ESRD (end-stage renal disease). Several states are required to sell at least one Medigap plan to those with a qualifying disability or ESRD. If you live in one of these states, your MOpen Enrollment Period starts when your Part B coverage begins.

Guaranteed Issue Rights

These rights require a Medicare insurance company to:

  • Offer at least one Medicare Supplement insurance plan
  • Include coverage for pre-existing conditions
  • Refrain from billing you a higher premium because of your past or current health condition

Examples of scenarios where guaranteed issue rights may apply, and you may receive a Special Enrollment Period:

  • You are employed or retired, and your group health plan is ending.
  • You had joined Medicare Advantage, and that plan is leaving your area.
  • You are losing Medicare Advantage because you relocated to a place not serviced by your plan.
  • You are under 65 and have a disability or end-stage renal disease (this is specific to Maryland and several other states).

Maryland's most popular Medigap plans include Plans F, G, and N.

You can switch anytime, but changing plans inside the six-month Open Enrollment Period is best. Outside of this period, you may not qualify for guaranteed issue rights. This would allow the insurance carrier to decide based on your medical history. As a result, you could face higher monthly premiums or be refused coverage.

No, you cannot be denied coverage for a Medicare Supplement insurance policy during your open enrollment period or if you qualify for guaranteed issue rights. Outside of this, the insurer may accept you at a higher premium or deny coverage based on previous health conditions.
