6. Specialty Referral Arrangements between Providers
Protects arrangements whereby one provider (which may be an individual or an entity) refers a specific patient to another provider, for specialty services, with the understanding that the specialty services provider will refer the patient back to the original provider at a certain time or under certain circumstances, as long as the following four standards are met:
the mutually agreed upon time or circumstance for referring the patient back to the originating provider is clinically appropriate;
the service for which the referral is made is not within the medical expertise of the referring provider, but is within the special expertise of the provider receiving the referral;
the providers do not receive payment from each other for the referral and do not split a global fee from a federal health program; and
the only payments either provider receives are from the patient or third-party payors for services the provider performs.
