When to sign up for Medicare
Initial Enrollment Period (IEP)
This is the seven-month period during which you can enroll in Medicare for the first time. Often this enrollment period occurs when you turn 65 or when you leave an employer-based plan after 65. If you are enrolling for the first time due to disability, your IEP timing is based on your disability date.
Annual Enrollment Period (AEP)
You can make changes to your medical and prescription drug coverage every year from Oct. 15–Dec. 7. Your changes are effective Jan. 1 of the following year.
Open Enrollment Period (OEP)
From Jan. 1 - March 31, if you currently have a Medicare Advantage plan you may switch to another Medicare Advantage plan, or disenroll from your current Medicare Advantage plan and return to Original Medicare.
Special Enrollment Period (SEP)
This is a period when Medicare recipients may change medical and prescription drug coverage outside of AEP, if they meet certain requirements and have a qualifying event, such as moving to a new service area or leaving an employer-based plan. Learn more about SEP.

5-star special enrollment period
From Dec. 8 - Nov. 30, you can use the 5-star Special Enrollment Period once yearly to switch from your current Medicare plan to a Medicare plan with a 5-star quality rating. Dean Medicare Advantage currently has a 5-star rating.
