Coverage under prefix OAG

HMO

This is a Health Maintenance Organization (HMO) prefix. HMO plans have stricter routing requirements than PPO plans. Members select a PCP who manages their care and issues referrals. Claims for specialist services should include the referral number. Out-of-network claims will typically be denied unless emergency criteria are met.

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.

HDHP

HDHP (High-Deductible Health Plan) coverage means the member has a higher deductible than traditional plans, often paired with a Health Savings Account (HSA). Most services require the member to pay out-of-pocket until the deductible is met. Preventive care is typically covered before the deductible. Submit claims normally to the payer listed above.
