Final answer:
A Medicare Supplement plan, also known as a Med Sup plan, helps cover the out-of-pocket costs that Original Medicare does not pay. It does not pay for the cost sharing of a Medicare Advantage plan (MA plan), but it can work in conjunction with Original Medicare to help cover these costs.
Step-by-step explanation:
A Med Sup plan, also known as a Medicare Supplement plan, is designed to help cover the out-of-pocket costs that Original Medicare does not pay, such as deductibles, copayments, and coinsurance. On the other hand, a MA plan, or Medicare Advantage plan, is an alternative to Original Medicare and combines both Part A and Part B coverage along with additional benefits.
While a Med Sup plan does not pay for the cost sharing of a MA plan, it can work in conjunction with Original Medicare to help cover these costs. In other words,
if you have an MA plan and decide to enroll in a Med Sup plan, the Med Sup plan will pay its share of the covered costs after Original Medicare has paid its share.
For example, let's say you have a MA plan with a $20 copayment for a doctor's visit. If you also have a Med Sup plan, your Med Sup plan may cover all or a portion of that $20 copayment, depending on the specific plan.
