Coverage under prefix E7X

Medicaid

This prefix is associated with Medicaid managed care. When a BCBS plan administers Medicaid, the claims process may differ from commercial coverage: different payer ID, different claims address, different prior authorization rules, and different timely filing limits. Always verify Medicaid-specific details before submitting.

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.

HMO

HMO (Health Maintenance Organization) plans require members to choose a primary care physician (PCP) and obtain referrals before seeing specialists. Out-of-network services are generally not covered except in emergencies. Claims must be submitted to the payer listed above and should include referral authorization when applicable.
