Coverage under prefix M8T

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.

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

This is a High-Deductible Health Plan (HDHP) prefix. These plans have minimum deductible thresholds set by the IRS. Members often use HSA funds to cover out-of-pocket costs. The plan's claims processing and payer ID are the same as the standard plan, but expect higher patient responsibility amounts on remittance.
