Coverage under prefix BGA

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.

POS

Under this POS prefix, the member can access care both in-network and out-of-network, with cost-sharing that varies based on how the care is accessed. In-network care coordinated through the member's PCP has the lowest out-of-pocket cost. Include referral documentation when billing at the in-network benefit level.

Medicare Advantage

Medicare Advantage coverage under this prefix means the plan administers Medicare Part A and Part B benefits on behalf of CMS. These claims may have different processing rules than commercial claims, including different prior authorization requirements and appeal timelines. CMS timely filing rules (365 days) typically apply.
