I work for a Medicaid managed care organization and am wondering about the appropriateness around encountering/billing multiple services for a client when the client is open to services in multiple facilities. For example, if a client is in a psychiatric residential treatment facility, can a case manager bill for services provided during the time as well, while the facility is also billing services for the client? The case manager would be maintaining contact with agencies for when the client is discharged from the facility and back in outpatient treatment.
