In general, enrollment or changes are allowed only during the annual election period, October 15 – December 7, 2018. Your plan will start January 1, 2019.

In certain situations, changes are also allowed at other times of the year. For example, people with Medicaid, those who get “Extra Help” paying for their drugs, those who have or are leaving employer coverage, and those who move out of the service area may be allowed to make a change at other times of the year.

If you enrolled in a Medicare Advantage plan for January 1, 2019, and don’t like your plan choice, you can switch to another Medicare health plan (either with or without Medicare prescription drug coverage) or switch to Original Medicare (either with or without Medicare prescription drug coverage) between January 1 and March 31, 2019.

If you don't qualify for a special election period and if you miss the annual election period, you must wait until October 15 – December 7, 2019. Your plan would start January 1, 2020. The Centers for Medicare & Medicaid Services (CMS) must approve your enrollment. Contact our representatives at the phone numbers listed in Contact Information for more information.

Note: If you have a group-sponsored health plan, please contact your benefits administrator before making any changes.

Please complete the entire form so we can process it for you without any delays.
