Medicare Part C, also known as Medicare Advantage (MA) plans, is an alternative to the traditional Medicare Parts A and B. These plans are offered by private insurance companies that contract with Medicare to provide comprehensive health care coverage, often including prescription drug coverage. In this post, we’ll break down the basics of Medicare Advantage plans, their benefits, and key details seniors should understand when considering this option.
What is Medicare Part C (Medicare Advantage)?
Medicare Part C combines hospital and doctor visit coverage from Medicare Part A and Medicare Part B into one plan. Offered by private insurance companies, these plans often come with extra benefits like vision, hearing, and dentalcoverage, as well as access to fitness programs. Many Medicare Advantage plans also include prescription drug coverage (Part D), which makes them a one-stop-shop for health care needs.
To join a Medicare Advantage plan, you must already be enrolled in Medicare Part A and Part B and continue paying your Part B premiums. Some plans also have an additional premium, while others may offer no premium or even refund part of your Medicare Part B premium.

-
Open Enrollment Period: The annual Medicare Advantage Open Enrollment Period runs from October 15 to December 7, during which you can join, switch, or leave a Medicare Advantage plan.
-
Disenrollment Period: If you’re unhappy with your Medicare Advantage plan, there’s a disenrollment periodfrom January 1 to March 31 each year. During this time, you can switch to Original Medicare.
