Coverage under prefix C5Y

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.

POS

This prefix is linked to a POS plan. Point of Service coverage gives members a choice at the time of service: use the HMO-style in-network benefit with a referral for lower costs, or access out-of-network providers at reduced coverage levels. The billing approach depends on which option the member chooses.

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.
