Coverage under prefix A8I

Medicare Advantage

This prefix includes Medicare Advantage coverage. MA plans follow CMS guidelines for timely filing (365 days from date of service), which may differ from the commercial plan's deadline. The payer ID for Medicare Advantage claims may differ from the standard commercial payer ID. Verify before submitting.

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.

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.
