Enrollment is generally for a calendar year. You can choose to leave your current Medicare MSA Plan between November 15 and December 31 of every year. Your request to disenroll during this time will be effective on the following January 1st. However, in certain cases, such as if you enter a nursing home or move; you can leave your plan at other times. If you leave the plan before the end of the year, you may have to repay some of the money in your account. After you request to leave, your plan will let you know, in writing, the date your coverage ends. If you don’t get a letter, call the plan and ask for the date.
If you want to leave your Medicare MSA Plan at the end of the year and return to Original Medicare, you need to contact your current plan, or call 1-800-MEDICARE (1-800-633-4227). TTY users should call 1-877-486-2048.
If you want to leave your current Medicare MSA Plan at the end of the year to join a new Medicare Advantage Plan at the beginning of the year, simply join the new plan. You don’t need to tell your old plan you are leaving or send them anything. You will be disenrolled automatically from your old plan when your new plan coverage begins. You should get a letter from your new plan telling you when your coverage starts. Joining a Medicare Prescription Drug Plan won’t automatically disenroll you from your Medicare MSA Plan.
Note: If you choose a Medicare MSA Plan for the first time and then change your mind, you can cancel your enrollment by December 15 of the same year. Contact the plan by December 15 if you would like to cancel your enrollment.
