WHEN A PLAN WILL NOT RETURN
My Medicare Advantage Plan Is Ending—What Happens Next?
If your Medicare Advantage plan is ending, do not cancel coverage impulsively. Save the plan notice, confirm the final coverage date and coordinate the medical, prescription and Medigap decisions that may follow.
If a Medicare Advantage plan will no longer participate in Medicare or will stop serving your area, the plan must notify affected members. The notice explains when coverage ends and how to review replacement coverage.
You may be able to join another Medicare Advantage plan or return to Original Medicare. If you return to Original Medicare, you may need separate Part D coverage, and a federal or state Medigap protection may apply depending on why the plan is ending and your circumstances.
Keep the complete notice. It can be important proof of the plan-ending event and any protected enrollment rights.
FIRST IDENTIFY THE EVENT
Is the Whole Plan Ending—or Did One Provider Leave?
| Situation | What changed | Why the distinction matters |
|---|---|---|
| Plan non-renewal or termination | The Medicare Advantage contract or plan will no longer be available to you | Special enrollment and Medigap protections may apply |
| Plan leaves your service area | The plan remains elsewhere but not where you live | You need coverage available at your residential address |
| Doctor or hospital leaves the network | The plan remains, but a provider relationship changes | This does not automatically create the same rights as the entire plan ending |
| You move outside the service area | Your residence no longer fits the plan’s service area | A moving-related Special Enrollment Period may apply |
If the plan remains available but a provider is changing, use the separate guide for a Medicare plan losing your doctor or hospital. If you moved, read Moving With Medicare.
YOUR COVERAGE PATHS
What Options May Be Available?
Choose another Medicare Advantage plan
Compare plans available at your address using your doctors, hospitals, prescriptions, pharmacies, costs and coverage preferences.
Return to Original Medicare
Original Medicare provides Part A and Part B coverage. You may need a stand-alone Part D plan and may want to investigate Medicare Supplement eligibility.
Use a protected Medigap right
When an Advantage plan leaves Medicare or stops serving your area, federal guaranteed-issue protections may apply if you switch to Original Medicare. The exact notice, timing and available plan letters matter.
Do not assume that the replacement with the lowest premium is automatically the best fit. The same complete annual review used during Medicare AEP in Springfield applies here too.
MEDIGAP PROTECTION
Could the Plan Ending Give You a Right to Buy Medigap?
Federal Medicare guidance lists certain guaranteed-issue situations involving Medicare Advantage plans, including when a plan leaves Medicare, stops providing care in your area or when you move outside its service area. These protections generally require you to return to Original Medicare rather than join another Medicare Advantage plan.
The permitted Medigap plan letters and application window depend on the protected situation and federal eligibility rules. State law may provide additional protections. Save:
- The plan-ending notice showing why and when coverage ends.
- The envelope and mailing date if timing could become important.
- Proof of prior coverage and any prior Medigap policy information.
- Every application and approval document showing the requested effective date.
Do not let Medicare Advantage coverage end before confirming the next steps. Medical coverage, Medigap and prescription coverage are related but separate decisions with separate applications and effective dates.
Read the detailed guide on switching from Medicare Advantage to a Medicare Supplement.
DO NOT FORGET PRESCRIPTIONS
Medical Coverage Ending Can Create a Drug-Coverage Decision
Most Medicare Advantage plans include Part D prescription coverage. If you move to Original Medicare, drug coverage does not automatically appear simply because Parts A and B continue.
Before the old plan ends, verify:
- Whether the replacement Advantage plan includes drug coverage.
- Whether you need a stand-alone Part D plan with Original Medicare.
- Whether every medication is covered under the new formulary.
- How your preferred pharmacy is treated by the new plan.
- Whether prior authorization, step therapy or quantity limits apply.
- Whether a transition fill may be needed at the start of coverage.
Use the guide for a prescription that is no longer covered if the replacement coverage treats one of your medications differently.
ACTION CHECKLIST
What to Do After Receiving the Notice
- Read the entire notice. Identify exactly why the plan is ending, the last day of coverage and the enrollment instructions.
- Keep the notice and envelope. Do not discard the proof after making a choice.
- Update your comparison information. Gather medications, dosages, pharmacies, doctors, hospitals and anticipated care.
- Compare both major coverage paths. Review another Medicare Advantage plan versus Original Medicare with separate drug coverage and possible Medigap.
- Investigate protected Medigap rights before the deadline. Do not assume that Open Enrollment alone guarantees acceptance.
- Coordinate effective dates. Verify that medical and drug coverage begin when the ending plan stops.
- Confirm enrollment. Keep confirmation numbers, approval notices and new member materials.
COMMON QUESTIONS
Medicare Advantage Plan Ending FAQ
Will I lose Medicare if my Medicare Advantage plan ends?
No. Medicare Advantage is a private way to receive Medicare benefits. Your underlying Medicare entitlement does not disappear, but you must coordinate the coverage that will replace the ending plan.
Will I automatically get another Medicare Advantage plan?
Do not assume that you will. Read the plan notice and compare the options available at your address. In some situations you may return to Original Medicare if another election is not made.
Does a plan ending guarantee any Medigap policy I want?
Not necessarily. A guaranteed-issue right may apply, but federal rules can limit the available plan letters and application timing. State protections may differ.
Is a doctor leaving the network the same as the plan ending?
No. A provider-network change can be important, but it does not automatically create the same enrollment and Medigap rights as a plan non-renewal or termination.
Should I cancel the ending plan myself?
Usually the safer approach is to coordinate the replacement election and effective dates rather than cancelling coverage early. Confirm the proper process with Medicare or the plan.
