Coverage under prefix NWW

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.

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.
