Mental health/medical care cost offsets: opportunities for managed care.

Health services researchers have long observed that outpatient mental health treatment sometimes leads to a reduction in unnecessary or excessive general medical care expenditures. Such reductions, or cost offsets, have been found following mental health treatment of distressed elderly medical inpatients, some patients as they develop major medical illnesses, primary care outpatients with multiple unexplained somatic complaints, and nonelderly adults with alcoholism. In this paper we argue that managed care has an opportunity to capture these medical care cost savings by training utilization managers to make mental health services more accessible to patients whose excessive use of medical care is related to psychological factors. For financial reasons, such policies are most likely to develop within health care plans that integrate the financing and management of mental health and medical/surgical benefits.
