You may want to drop your Medigap policy.
Your Medigap policy can’t pay any Medicare Advantage Plan deductibles, copayments, coinsurance, or premiums, if you decide to keep your Medigap policy.
Keep in mind that if you drop your Medigap policy, in most cases you won’t be able to get it back, so pay attention to the timing.
In general, you can only join a Medicare Advantage Plan during the Medicare Open Enrollment Period between October 15 – December 7 each year. If you join during Open Enrollment, your Medicare Advantage Plan coverage will begin on January 1.
Contact your Medigap insurance company to cancel your Medigap policy.
