What is a key feature of Medicare Advantage plans?

Medicare Advantage plans, also known as Medicare Part C, typically require enrollees to use a network of doctors and facilities that have agreed to provide services to the plan's members. This network structure is a defining characteristic of these plans, which often provide additional benefits beyond those covered by traditional Medicare (Part A and Part B).

By utilizing a network, Medicare Advantage plans can manage costs and coordinate care more efficiently. For enrollees, this often means that while they may have lower out-of-pocket costs when using in-network providers, they might face higher costs or need referrals to see out-of-network specialists. This network requirement emphasizes the importance of access to coordinated healthcare services while attempting to maintain affordability for members.

The other options, while relevant in the context of healthcare coverage, do not accurately describe the core feature of Medicare Advantage plans: the emphasis on using a specific network of providers.
