Exclusive provider organizations (EPOs) provide benefits to subscribers if they use services from?

Exclusive provider organizations (EPOs) are a type of managed care health insurance plan that limits coverage to care provided by doctors and hospitals that are part of the plan's network. If subscribers choose to receive care from out-of-network providers, they typically do not receive any benefits, except in emergencies. Therefore, the correct answer is that EPOs provide benefits to subscribers if they use services from network providers.

This design incentivizes members to utilize healthcare providers who have agreed to provide services at negotiated rates, which can help control costs for both the insurer and the subscribers. Subscribers have a defined set of healthcare providers from which they can choose, ensuring a degree of cost-effectiveness and streamlined care management.

In contrast, the other options do not accurately represent the structure of EPOs. The Office of Managed Care refers to regulatory bodies rather than specific providers. Case managers typically coordinate care rather than deliver services directly, and medical foundations do not inherently represent the network-provider concept associated with EPOs.
