Coverage under prefix X3S

EPO

This prefix is associated with an EPO plan. Exclusive Provider Organization coverage combines elements of HMO and PPO plans: members must stay in-network like an HMO, but can self-refer to specialists like a PPO. Out-of-network services are not covered except for emergencies.

Medicare Advantage

Medicare Advantage (MA) coverage means this member receives their Medicare benefits through a private BCBS plan rather than through original Medicare. MA plans may have different payer IDs and claims addresses than the commercial plan. Check with the payer to confirm the correct submission details for Medicare Advantage claims.

PPO

PPO (Preferred Provider Organization) plans allow members to visit any healthcare provider without a referral. In-network providers cost less, but out-of-network care is still covered at a reduced rate. When billing for a PPO plan, submit claims directly to the payer listed above. No referral documentation is needed.
