Coverage under prefix S5K

HMO

HMO coverage means this member must use providers within the plan's network. A primary care physician serves as the care coordinator and must authorize specialist referrals. Emergency services are the primary exception to the network requirement. Always verify referral status before providing non-emergency specialty care.

Medicaid

This prefix includes Medicaid managed care coverage. The BCBS plan administers Medicaid benefits on behalf of the state. Claims submission, prior authorization, and reimbursement rules may follow state Medicaid guidelines rather than the plan's standard commercial policies. Confirm the correct payer ID for Medicaid claims.

PPO

This prefix is associated with a PPO plan. Preferred Provider Organization coverage gives members flexibility to see specialists without referrals and to use out-of-network providers at higher cost-sharing. Claims can be submitted for both in-network and out-of-network services, though reimbursement rates differ.
