Coverage under prefix M4Y

EPO

EPO (Exclusive Provider Organization) plans require members to use in-network providers, similar to an HMO. The key difference is that referrals are usually not required to see a specialist. Out-of-network care is not covered except in emergency situations. Submit claims to the payer listed above.

HMO

HMO (Health Maintenance Organization) plans require members to choose a primary care physician (PCP) and obtain referrals before seeing specialists. Out-of-network services are generally not covered except in emergencies. Claims must be submitted to the payer listed above and should include referral authorization when applicable.

Traditional Indemnity

This is a traditional indemnity prefix. Unlike managed care plans (HMO, PPO, EPO), indemnity plans do not use provider networks. There are no referral requirements and no restrictions on which providers the member can see. Submit claims to the payer listed above for reimbursement at the plan's allowed rate.
