Coverage under prefix T4Z

HMO

HMO coverage means this member must use providers within the plan's network. A primary care physician serves as the care coordinator and must authorize specialist referrals. Emergency services are the primary exception to the network requirement. Always verify referral status before providing non-emergency specialty care.

PPO

This prefix is associated with a PPO plan. Preferred Provider Organization coverage gives members flexibility to see specialists without referrals and to use out-of-network providers at higher cost-sharing. Claims can be submitted for both in-network and out-of-network services, though reimbursement rates differ.

EPO

EPO coverage under this prefix means the member must use network providers but does not need referrals for specialist visits. This plan type is becoming more common as it offers lower premiums than PPO plans while providing more flexibility than HMOs. Verify network status before providing services.
