CMHA-CEI receives a monthly pre-payment for each Medicaid recipient living in this community, as well as the communities of each of our affiliate CMHs. The monthly payment, known as the Per Enrollee Per Month payment (PEPM) differs by the age, gender, and Medicaid enrollment type of each enrollee, and is distributed among the affiliates accordingly. In our PIHP role, CMHA-CEI must serve the mental health needs, above those of mild severity (which are served by Medicaid HMOs), of any and all Medicaid recipients living in the tri-county region. No new Medicaid funds are provided to CMHA-CEI if demand for services increases. Under such an arrangement, the CMH system serves in many ways as a staff model HMO for mental health and developmental disability services.
