Coverage under prefix IIA

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.

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.

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.
