A more thorough explanation:

Managed care is a type of healthcare system that is provided by a group such as a health-maintenance organization or a preferred-provider organization. This system offers comprehensive healthcare services to its members.

For example, a health-maintenance organization (HMO) is a type of managed care organization that provides healthcare services to its members for a fixed fee. Members of an HMO can only receive healthcare services from providers that are part of the HMO's network. This means that the HMO manages the healthcare services that its members receive.

Another example of managed care is a preferred-provider organization (PPO). A PPO is a group of healthcare providers that have agreed to provide services to members of the PPO at a discounted rate. Members of a PPO can choose to receive healthcare services from any provider within the PPO's network, but they will pay less if they choose a provider that is part of the PPO's network.

These examples illustrate how managed care organizations work to provide comprehensive healthcare services to their members while managing costs and ensuring quality care.
