Situation

What Can I do?

Coverage begins:

I'm newly eligible for Medicare because I have a disability (under 65).

Sign up for a Medicare Advantage Plan or a Medicare drug plan.

If you join during one of the 3 months before you first get Medicare, your coverage begins the first day of your 25th month of entitlement to Social Security or Railroad Retirement Board (RRB) disability benefits

If you join during your 25th month of getting disability, your coverage begins the first day of the month after you ask to join the plan

If you join during one of the 3 months after your 25th month of getting disability, your coverage begins the first day of the month after you ask to join the plan

I'm already eligible for Medicare because of a disability, and I turned 65.

• Switch from your current Medicare Advantage Plan or Medicare drug plan to another plan.

• Drop a Medicare Advantage Plan or a Medicare drug plan completely.

If you were eligible for Medicare because of a disability before age 65, you’ll have another Initial Enrollment Period based on age.

• If you join during one of the 3 months before you turn 65, your coverage begins the first day of the month you turn 65

• If you join during the month you turn 65, your coverage begins the first day of the month after you ask to join the plan

• If you join during one of the 3 months after you turn 65, your coverage begins the first day of the month after you ask to join the plan

Note: If you sign up for a Medicare Advantage Plan during this time, you can drop that plan during the next 12 months and go back to Original Medicare.

I don't have Part A, and I signed up for Part B during the General Enrollment Period (January 1–March 31).

Sign up for a Medicare drug plan.

If you join April 1-June 30, your coverage begins July 1.

I have Part A coverage, and I signed up for Part B during the General Enrollment Period (January 1–March 31).

Sign up for a Medicare Advantage Plan (with or without drug coverage).

If you join the 3 months before your Part B starts, your coverage will start the same day as when your Part B coverage starts.

I’m losing my coverage because my plan stopped participating in Medicare.

Choose another plan between October 15–December 7.

You’ll also have a special right to join another Medicare plan until the last day in February.

If you choose another plan between October 15–December 7, or from December 8-December 31, your coverage will begin January 1.

If you choose another plan in January, coverage begins February 1.

If you choose another plan in February, coverage begins March 1.

You may have the right to buy certain Medigap policies within 63 days after your plan coverage ends.

I'm losing my SNP coverage because I no longer meet the special conditions served by the plan. 

The grace period is at least one month long, but plans can choose to have a longer grace period. If you lose eligibility for the plan, you'll have a Special Enrollment Period to make another choice.

This Special Enrollment Period starts when your Medicare SNP notifies you that you're no longer eligible for the plan. 

It continues during the plan's grace period, and if you're disenrolled from the plan at the end of the grace period, it continues for 2 months after your coverage ends. 

It's very important to review your coverage options at this time to make sure you continue to have the Medicare health and prescription drug coverage you want.
