Coverage under prefix AOU

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.

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.

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.

Medicare Advantage

Medicare Advantage coverage under this prefix means the plan administers Medicare Part A and Part B benefits on behalf of CMS. These claims may have different processing rules than commercial claims, including different prior authorization requirements and appeal timelines. CMS timely filing rules (365 days) typically apply.
