Coverage under prefix C9O

Medicaid

Medicaid managed care under this BCBS prefix means the state has contracted with this plan to administer Medicaid benefits. Balance billing Medicaid members is prohibited. Timely filing requirements may follow state Medicaid rules rather than the plan's commercial deadlines. Contact the plan to confirm submission requirements.

PPO

PPO coverage under this prefix means the member can access any provider. In-network providers have negotiated rates with the plan, while out-of-network providers are reimbursed based on usual and customary charges. Prior authorization is generally not required for routine services but may be needed for high-cost procedures.

Traditional Indemnity

This prefix includes traditional indemnity coverage. Indemnity plans are the oldest form of health insurance and offer maximum provider choice with no network restrictions. Members pay a percentage of charges after meeting their deductible. Reimbursement is based on reasonable and customary rates for the service area.
