Understanding when you can change your Medicare Advantage coverage outside the Annual Enrollment Period in Connecticut.
Last updated: January 2026 | Written by licensed CT insurance professionals
The Short Answer
You can switch Medicare Advantage plans mid-year only during the Medicare Advantage Open Enrollment Period (January 1 – March 31), or if you qualify for a Special Enrollment Period due to a life event like moving, losing coverage, or qualifying for Extra Help. Otherwise, you must wait for the Annual Enrollment Period (October 15 – December 7).

Special Enrollment Period Qualifying Events
These life events may allow you to switch plans outside regular enrollment periods
Important: Each SEP has specific timeframes (usually 60-63 days from the event). Documentation may be required. Contact us to verify your eligibility.
