Definition
(1) An EPO is a form of PPO, in which patients must visit a caregiver that is specified on its panel of providers (is a participating provider). If a visit to an outside(not participating) provider is made the EPO offers very limited or no coverage for the medical service; (2) While similar to a PPO in that an EPO allows patients to go outside the network for care, if they do so in an EPO, they are required to pay the entire cost of care. An EPO differs from an HMO in that EPO physicians do not receive capitation but instead are reimbursed only for actual services provided; (3) An organization identical to a preferred provider organization except that persons enrolled in the plan are eligible to receive benefits only when they use the services of the contracting providers. No benefits are available when non-contracting providers are used, except in certain emergency situations.

Where 302F00000X sits
- Group: Managed Care Organizations — code 1 of 4 in the group
- Classification: Exclusive Provider Organization 302F00000X
Exclusive Provider Organization has no specializations, so 302F00000X is the only code for it. A provider may report more than one taxonomy code on an NPI but marks one as primary.
Medicare
302F00000X has no entry in the CMS Medicare Provider and Supplier Taxonomy Crosswalk. That usually means Medicare does not enroll this kind of provider under its own specialty — organizations of this type enroll, if at all, under a facility or supplier type rather than a practitioner specialty.

Using 302F00000X
The code goes in the taxonomy field of the NPI application in NPPES, and on claims where a payer asks for it — box 24J (shaded) or 33b on the CMS-1500 with the ZZ qualifier, or the PRV segment of an 837 electronic claim. Payers match it against the taxonomy on the NPI record and, for Medicare, against the specialty on the enrollment, so all three should agree. To see which code a provider uses, search their NPI in the lookup.
