Which of the following is not a type of MA plan?

Medicare supplement insurance plans are not categorized as a type of Medicare Advantage (MA) plan. Instead, these plans are designed to help cover costs that Original Medicare (Parts A and B) does not cover, such as copayments, coinsurance, and deductibles. They serve as an additional layer of coverage for beneficiaries who have Original Medicare.

On the other hand, Private Fee for Service Plans (PFFS), Health Maintenance Organization (HMO) plans, and Preferred Provider Organization (PPO) plans are all classifications of Medicare Advantage plans. These MA plans provide a way for beneficiaries to receive their Medicare benefits through private health insurance companies rather than directly from the government. Each of these types of plans has distinct features and structures for how healthcare services are accessed and how patients can seek care, making them part of the Medicare Advantage program, unlike Medicare supplement plans.
