Find Your Perfect
Medicare Plan
Medicare Advantage plans are approved by Medicare but are run by private companies. These companies provide Medicare Part A and Part B covered services and may include Medicare drug coverage too. Medicare Advantage plans are sometimes called “Part C” or “MA” plans. MA plans are not supplemental insurance. MA plans may not be free. It is important to understand the cost sharing of each plan’s premiums, deductibles and copayments. MA plans may require you to use only doctors and hospitals in their network
