Coverage under prefix S3O

EPO

EPO (Exclusive Provider Organization) plans require members to use in-network providers, similar to an HMO. The key difference is that referrals are usually not required to see a specialist. Out-of-network care is not covered except in emergency situations. Submit claims to the payer listed above.

PPO

Under this PPO prefix, members are covered for both in-network and out-of-network care. The plan pays a higher percentage of allowed charges when members use participating providers. No gatekeeper or primary care referral is required. Verify the member's specific benefits for cost-sharing details.

Medicare Advantage

Under this prefix, the member may have Medicare Advantage coverage administered by this BCBS plan. MA claims are subject to CMS regulations in addition to the plan's own policies. Balance billing restrictions apply. Verify the member's specific MA plan details and confirm the correct payer ID for electronic submission.
