Coverage under prefix A8C

EPO

This prefix is associated with an EPO plan. Exclusive Provider Organization coverage combines elements of HMO and PPO plans: members must stay in-network like an HMO, but can self-refer to specialists like a PPO. Out-of-network services are not covered except for emergencies.

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.

POS

POS (Point of Service) plans combine features of HMO and PPO coverage. Members choose a primary care physician and can get referrals to see in-network specialists at lower cost, or self-refer to out-of-network providers at higher cost. Claims should include referral information when the member uses the in-network benefit level.
