The AEP begins every year on October 15 and ends on December 7. This is why your mailbox, web browsers, and TV screens fill up with commercials and ads from insurance companies hoping to get you to buy or switch Medicare Advantage or Medicare Part D Prescription Drug Plans during this time period.
This is when you can change your Medicare Advantage plan or your Medicare Part D Prescription Drug Plan if you want. For instance, during the AEP, you can move from Original Medicare to Medicare Advantage or vice versa. You may also switch from one Medicare Advantage plan to another Medicare Advantage plan that may better suit your needs or your budget.
Likewise, you may also switch from one Medicare Part D Prescription Drug Plan to another, or you may join or leave a Medicare Part D plan altogether. Provided that you make any of these changes during the AEP, your new coverage will take effect on the following January 1, and your old one will immediately be dropped with no gap in coverage.
If you don’t do anything or change anything, you just roll over and stay on the plan you have for the next year.
This does not apply to Medicare Supplement (Medigap) insurance. This period is only for changing Medicare Advantage Plans and Medicare Part D Prescription Drug Plans.
Many authors and journalists mistakenly call the AEP “Open Enrollment” or “Annual Open Enrollment.” It’s not. It’s the Annual Election Period.
