Coverage under prefix ONT

HDHP

Under this HDHP prefix, the member's plan has a higher deductible than traditional coverage. This affects patient cost-sharing but does not change how claims are submitted or processed. Use the same payer ID, claims address, and filing procedures listed above. Verify the member's remaining deductible before estimating patient responsibility.

Medicare Advantage

Medicare Advantage (MA) coverage means this member receives their Medicare benefits through a private BCBS plan rather than through original Medicare. MA plans may have different payer IDs and claims addresses than the commercial plan. Check with the payer to confirm the correct submission details for Medicare Advantage claims.

EPO

EPO coverage under this prefix means the member must use network providers but does not need referrals for specialist visits. This plan type is becoming more common as it offers lower premiums than PPO plans while providing more flexibility than HMOs. Verify network status before providing services.
