Coverage under prefix OSO

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

Under this prefix, the member may have Medicaid coverage managed by this BCBS plan. Medicaid claims have specific rules around cost-sharing, balance billing, and timely filing that override the plan's standard commercial policies. Contact the plan's Medicaid provider services line for submission details.

Traditional Indemnity

Under this indemnity prefix, the member has fee-for-service coverage. There is no provider network, no referral requirement, and no primary care physician gatekeeper. Claims are processed based on the plan's fee schedule. While less common than managed care plans, indemnity coverage is still offered by some BCBS companies.
