    Can I join a Medicare Advantage plan?

    Medicare Advantage Plans (Part C) is both Part A and Part B coverage (also known as Original Medicare).1 This can include dental, vision, and prescription drug coverage, as well as no-cost extras.

    If you want to enroll, you must:

    • Be eligible for Medicare
    • Be enrolled in both Medicare Part A and Part B (you can check this by referring to your red, white, and blue Medicare card)
    • Live within the plan’s service area (which is based on the county you live in–not the state)

    Once you are enrolled, the private company supporting your Medicare plan (like Cigna HealthcareSM) will set up your benefits. You do not lose your Original Medicare.

    When can I sign up?

    If you are eligible for Medicare Advantage, you can enroll during the Annual Enrollment Period (AEP). This is from October 15 - December 7, each year.

    When can I switch Medicare Advantage plans?

    With a Medicare Advantage (MA) plan, you can switch plans during the following periods, which happen every year:

    • Annual Enrollment Period (AEP): From October 15-December 7, you can leave your MA plan and switch to Original Medicare.
    • Medicare Advantage Open Enrollment: From January 1-March 31, you can switch to another Medicare Advantage planwith or without drug coverageor switch back to Original Medicare Part A and B. You can add a Part D drug plan, too, if you need one. You can only make one change to your Medicare Advantage plan during this period. Your new coverage will begin the first of the month after you make the switch.

    If you need to change your Medicare Advantage plan outside of these standard periods, you may be eligible for a Special Enrollment Period (SEP) if you have a qualifying event like moving outside your plan's coverage area. Depending on the event, you'll have 30-60 days to change your plan. To confirm if you're eligible for a SEP, contact us.

    How do I enroll?

    You can enroll online, call us, or even fax or mail us. Be sure to review our Enrollment Disclaimers before you sign up.
