Coverage under prefix GRA

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.

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.

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.
