What is the function of Medicare Advantage Plans?

Medicare Advantage Plans, also known as Medicare Part C, function primarily to offer managed care coverage through private insurers. These plans are an alternative to traditional Medicare, allowing beneficiaries to receive their Medicare benefits through private health insurance companies that contract with Medicare.

The key aspect of Medicare Advantage is that these plans often incorporate additional benefits beyond what is typically covered by traditional Medicare, including vision, dental, and sometimes even fitness services. They may also implement care management practices that aim to control costs and improve the quality of care, which aligns with the managed care model.

This approach allows beneficiaries the flexibility of choosing a plan that best meets their healthcare needs while often including features such as coordinated care and network-based resources. Thus, the correct answer highlights the essential function of these plans in the context of Medicare's broader framework.
