Medicare Part C (Medicare Advantage Plans) is another way to get your Medicare benefits. It combines Part A, Part B, and sometimes Part D (prescription drug) coverage. Medicare Advantage Plans are managed by private insurance companies approved by Medicare. These plans must cover medically-necessary services.
Medicare C is reported on Form 1099-SA Distributions from an HSA, Archer MSA, or Medicare Advantage MSA. The amount included in income is the amount not used to pay medical expenses. Generally, if you receive a taxable distribution, you must also pay an additional tax on the amount included in income. The additional tax for Medicare Advantage MSAs is 50%.

With these plans, you can’t have a Medigap policy, because Medicare Advantage plans cover many of the same benefits a Medigap policy covers. This includes benefits like extra days in the hospital after you’ve used the days that Medicare covers.
Medicare Advantage plans include all of the following:
If you decide to join a Medicare Advantage plan, you use the health card that you get from your Medicare Advantage plan provider for your health care. Also, you might have to pay a monthly premium for your Medicare Advantage plan because of the extra benefits it offers.
