Coverage under prefix S3U

HMO

Under this HMO prefix, the member's coverage is limited to the plan's provider network. Care is coordinated through a primary care physician. Specialist visits require a referral from the PCP. When billing, confirm that the referring provider and the referral authorization number are included on the claim.

Traditional Indemnity

This is a traditional indemnity prefix. Unlike managed care plans (HMO, PPO, EPO), indemnity plans do not use provider networks. There are no referral requirements and no restrictions on which providers the member can see. Submit claims to the payer listed above for reimbursement at the plan's allowed rate.

Medicaid

Medicaid coverage under this prefix means the member's Medicaid benefits are administered by a BCBS managed care plan. Medicaid managed care claims may have different submission requirements, payer IDs, and timely filing deadlines than commercial claims. Verify the specific Medicaid plan details with the payer.
