Managed Care Organizations (MCOs): is a group of people working together to manage the cost of health care. MCOs work along with medical facilities and health care providers to render support to MCO patients. MCOs only pays for the care provided and its plan is not as flexible as ACOs. MCOs give incentives to physicians like the ACOs. There are four types of MCOs: Health Maintenance Organization (HMO), Preferred Provider Organization (PPO), Exclusive Provider Organization (EPO), and Point-of-Service Plan (POS). According to (Andrews, 2014), HMOs only pay within network health care and insurers need a referral to seek care from a specialist or else the services provider will not be covered. For PPOs, care is covered both in and out of the network, however; the patient pays a higher premium for out of network care. In EPO, care is not covered outside of the network, nevertheless; patients do not require referral to get seen by a specialist. In POS, plan varies between HMOs and PPOs, and insurers may seek out of network care but with a higher cost-sharing rate. PPO and HMO both have Medicare options.
