Supreme Court of the United States May 20, 1985, 83-2136 (Connecticut Department of Income Maintenance v. Heckler)

Justice Stevens

delivered the opinion of the Court.

Services performed for patients between the ages of 21 and 65 in an “institution for mental diseases” (IMD) are not covered by the Medicaid Act. The Secretary of Health and Human Services has adopted a definition of that term that is broad enough to encompass an “intermediate care facility” (ICF).
