How do I cancel my Medicare Advantage plan?

You rarely cancel directly. In most cases you enroll in something else and the old plan ends on its own. Here is the right sequence.

Cancelling an Advantage plan is more about what you enroll in next than about the cancellation itself. Done in the wrong order it leaves gaps.

The usual way it happens

You do not call and cancel. You enroll in your next arrangement and the old plan terminates automatically.

• Enroll in a different Advantage plan and the old one ends when the new one starts.
• Enroll in a standalone Part D plan while on Original Medicare and your Advantage plan ends automatically.
• Only if you want Original Medicare with no drug plan at all do you contact the plan or Medicare directly to disenroll, and that choice starts a Part D penalty clock.

When you can do it

• Annual Enrollment, October 15 to December 7, effective January 1
• Advantage Open Enrollment, January 1 to March 31, effective the first of the next month
• A special enrollment period if you moved, lost or gained Medicaid or Extra Help, entered or left a nursing facility, or your plan left the area

Outside those, you generally stay put. Dissatisfaction alone is not a qualifying event.

Before you cancel, in this order

1. Decide what you are moving to. Another Advantage plan, or Original Medicare with a supplement and a drug plan.
2. If you want a supplement, apply and get written approval first. In Texas you can be declined outside a protected window. See the underwriting rules.
3. Line up drug coverage for the same effective date.
4. Then complete the enrollment that triggers the cancellation.
5. Confirm the new coverage in writing before the old plan's end date.

Timing your effective dates

Coverage should be continuous. Advantage plans end on the last day of a month and new coverage begins on the first of the next. Do not let a gap open in between, even a short one, because a hospitalization inside it is entirely on you.

If you are cancelling because of a problem

Sometimes the better move is not cancellation.

• A denied service can be appealed, and appeals succeed more often than people assume.
• A doctor leaving the network may be covered by a continuity of care provision for a period.
• A drug moved to a higher tier can sometimes be handled with a formulary exception request from your doctor.

Those are worth trying, especially if you are outside an enrollment window anyway.

Auto renewal

If you do nothing, your plan renews automatically each January with whatever changes it made for the new year. That is fine when the changes are minor and expensive when they are not.

The Annual Notice of Change that arrives in September is the document that tells you which. See how to read it.
