Total Health Care, Inc., a fully licensed and federally qualified managed care organization, was founded and incorporated as a non-profit corporation on July 16, 1973 and is the oldest HMO in southeastern Michigan. It was first incorporated as Model Neighborhood Total Health Care (MNTHC), part of the federally subsidized model neighborhood programs of then President Lyndon B. Johnson. The organization had a strong community orientation and was located strategically within the City of Detroit at a major hospital center.
In November 1982, the organization was reincorporated under the name Total Health Care, Inc. and functioned as a staff model HMO whose delivery system consisted of three health centers, six associated hospitals, and several related referral facilities. To ensure the ability to expand the market outside the Detroit city limits, Total Health Care expanded its service area in mid-1981 to include all of Wayne, Oakland, and Macomb counties, as well as portions of Monroe County. THC evolved to a mixed model HMO (staff/IPA) for a period of time, but assumed a strictly network IPA model in 1984.
