This paper investigates the extent to which private supplementary insurance and Medicaid, which vitiate the effect of Medicare cost-sharing, encourage elderly beneficiaries to seek additional medical care. A multivariate model of health services utilization is estimated with the Tobit technique, using the 1976 Health Interview Survey. We find that either private or public supplementation induces greater use of hospital and physician services, though in amounts that vary considerably according to health status. The paper closes with observations on cost savings brought about by Medicare cost-sharing and some implications for equity among beneficiaries.

A residential facility that treated preadolescent children suffering from functional nervous disorders was considered to be a "hospital" for purposes of coverage under a group medical insurance policy, despite the fact that it lacked an on-premises surgical facility and did not provide 24-hour nursing services by registered nurses. The insurance company had waived the surgical facility requirement. Additionally, since the policy in question did not contain a definition of "nursing services," there was no requirement that these services be provided 24 hours a day by registered nurses. Thus the insureds were entitled to coverage of the treatment for their son in the residential facility. But a bad faith claim was denied because the insurer's interpretation of its policy was not found to be unreasonable.
