With a managed care model in place long before behavioral health integration, Tennessee did not need to require any new information systems. The MCOs already had developed systems for eligibility, administrative, and claims data. The MCOs were also used to submitting their data to the state. The only change for the state has been that instead of receiving data from both MCOs and BHOs, all the data now come from MCOs. EHRs are not required by the state or MCOs, but many providers now use them. Most providers also bill their MCOs electronically, but again, this is not required. According to one MCO representative, sharing information between plans and providers can result in better patient care, although sharing data does necessitate addressing privacy concerns.
