Coverage under prefix C8S

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

Under this EPO prefix, the member has no out-of-network coverage for routine care. However, unlike HMO plans, no referral is needed to see a specialist within the network. When billing, confirm the provider's network participation status with the plan before submitting the claim.

HDHP

Under this HDHP prefix, the member's plan has a higher deductible than traditional coverage. This affects patient cost-sharing but does not change how claims are submitted or processed. Use the same payer ID, claims address, and filing procedures listed above. Verify the member's remaining deductible before estimating patient responsibility.
