How do I cancel my Medicare Advantage plan?

You rarely cancel directly. You enroll in your next coverage and the old plan ends on its own. The order you do it in decides whether a gap opens.

You almost never cancel an Advantage plan by calling and asking for it to stop. You sign up for your next coverage, and the old plan ends on its own. Done in the wrong order, it leaves you with a gap.

How cancelling usually happens: you enroll in something else

Your next enrollment is what does the cancelling. There are three ways it plays out.

• You enroll in a different Advantage plan. The old one ends the day the new one starts.
• You go back to Original Medicare, the government's own coverage, and add a standalone Part D plan, a drug plan bought by itself. That ends your Advantage plan automatically.
• You want Original Medicare with no drug plan at all. Only then do you call the plan or Medicare and ask to disenroll, meaning to be taken off. That choice starts a Part D penalty clock, a late fee for going without drug coverage.

When you can cancel

• Annual Enrollment, October 15 to December 7. The change starts January 1.
• Advantage Open Enrollment, January 1 to March 31. The change starts the first of the next month.
• A special enrollment period, a window Medicare opens after certain life events. You get one if you moved, lost or gained Medicaid or Extra Help, entered or left a nursing facility, or your plan left the area. Extra Help pays part of drug costs.

Outside those windows you stay where you are. Being unhappy is not a life event Medicare accepts.

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, a separate policy that pays the share of the bills Medicare leaves to you, apply and get written approval first. In Texas you can be declined outside a protected window. See the health questions you may face.
3. Line up drug coverage to start the same day.
4. Then finish the enrollment that ends the old plan.
5. Confirm the new coverage in writing before the old plan's last day.

Timing your effective dates

Your coverage should run without a break. An Advantage plan ends on the last day of a month, and new coverage starts on the first of the next.

Do not let even a few days open in between. A hospital stay inside that gap is entirely on you.

If you are cancelling because of a problem

If one thing went wrong, there may be a fix short of leaving.

• A denied service can be appealed. Appeals succeed more often than people assume.
• A doctor who leaves the network, the list of doctors and hospitals the plan contracts with, may stay covered for a period under a continuity of care rule.
• A drug moved to a higher tier, a costlier level on the plan's drug list, can sometimes be moved back. Your doctor asks the plan for an exception.

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

Auto renewal each January

If you do nothing, your plan renews on its own every January with whatever changes it made for the new year. Some years the changes are small. Some years they cost real money.

The Annual Notice of Change (ANOC), the letter your plan mails in September, tells you which kind of year this is. See how to read it.

Decide where you are going before you touch the plan you have, and set the dates so nothing lapses. If you want help, call our McAllen office at (956) 687 3334, or enter your ZIP code in the form on this page.
