Coverage under prefix OLB

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.

POS

This is a Point of Service (POS) prefix. POS plans offer flexibility similar to a PPO but incentivize in-network care through lower cost-sharing. Members designate a primary care physician who can issue referrals for the highest level of benefits. Out-of-network claims are covered but at significantly reduced rates.

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.
