Medical Necessity and the Public Funding of In Vitro Fertilization in Ontario.

The recognition of a health care service as medically necessary under the Canada Health Act is contingent on a variety of practical and political factors. This article examines how in vitro fertilization (IVF) came to be understood as a medically necessary service in Ontario, focusing on the establishment of public funding for one cycle of treatment. The article argues that the legitimacy of medical necessity in the contemporary period is tied to three interrelated factors: the recognition of a service as sufficiently "medical," as efficient and as urgent—that is, something to be funded now and not later. By applying this framework to the case of IVF in Ontario, the article demonstrates not only the ongoing malleability of medical necessity but also how the government of Ontario has mobilized the three aspects of medical necessity to make a case for the public funding of a highly contested health care service.
