There are three major types of group health plans, they include:
Health Maintenance Organization (HMO) – With an HMO plan, you must see doctors within your plans network or pay more for health services. You will need a referral to see specialists under this type of plan. HMOs are relatively affordable, compared to other plan types.
Preferred Provider Organization (PPO) – PPO plans allow you to see out-of-network doctors, but in-network providers will be less expensive. With a PPO plan, you don’t need to get a referral to see specialists.
Exclusive Provider Plan (EPO) – EPO plans combine the benefits of HMO and PPO plans. You will need to see in-network providers, but you don’t need a referral to see specialists. This plan’s costs fall between PPO and HMO plans, with PPO plans being the most affordable.
