Coverage under prefix HSO

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.

Medicaid

Under this prefix, the member may have Medicaid coverage managed by this BCBS plan. Medicaid claims have specific rules around cost-sharing, balance billing, and timely filing that override the plan's standard commercial policies. Contact the plan's Medicaid provider services line for submission details.

PPO

This is a Preferred Provider Organization (PPO) prefix. PPO plans are the most common BCBS plan type. Members have the freedom to self-refer to specialists. Claims for in-network services are typically processed faster and reimbursed at higher rates than out-of-network claims.
