Coverage under prefix AUB

HMO

Under this HMO prefix, the member's coverage is limited to the plan's provider network. Care is coordinated through a primary care physician. Specialist visits require a referral from the PCP. When billing, confirm that the referring provider and the referral authorization number are included on the claim.

PPO

PPO (Preferred Provider Organization) plans allow members to visit any healthcare provider without a referral. In-network providers cost less, but out-of-network care is still covered at a reduced rate. When billing for a PPO plan, submit claims directly to the payer listed above. No referral documentation is needed.

Medicare Advantage

This prefix includes Medicare Advantage coverage. MA plans follow CMS guidelines for timely filing (365 days from date of service), which may differ from the commercial plan's deadline. The payer ID for Medicare Advantage claims may differ from the standard commercial payer ID. Verify before submitting.
