State laws mandating mental health insurance coverage.

Insurance companies and administrators of group insurance plans have accepted the premise that coverage for mental illness must be different from coverage for other health problems, and thus insurers continue to limit their liability through various exclusions and restrictions. For several years providers and consumers of services have worked for the enactment of state laws that mandate or regulate certain kinds of coverage for mental illness; as of January 1, 1977, a total of 22 states had such statutes. The author presents a state-by-state summary of the provisions. He also classifies many of the provisions into six categories and discusses the probable basis for their enactment.
