Institutions for Mental Diseases
An Institution for Mental Diseases (IMD’s) are hospitals, nursing facilities or other institutions of
more than sixteen (16) beds that are primarily engaged in providing diagnosis, treatment or care
of persons with mental diseases, including medical attention, nursing care and related services.
A. Individuals under age twenty-one (21) may receive Medicaid while in an institution for mental
diseases if they are receiving psychiatric services and are otherwise eligible. If the individual
is receiving inpatient psychiatric services at the time the individual turns age twenty-one (21),
the individual may receive Medicaid until age twenty-two (22).
B. Individuals between the ages of twenty-one (21) and sixty-five (65) are not eligible to receive
any Medicaid benefits while residing in an institution for mental diseases, with the following
exception:
1. A Medicaid eligible pregnant woman who is receiving treatment for a substance use
disorder is eligible to receive Medicaid covered services provided outside the IMD facility.
2. Pregnancy-related Medicaid may be determined prior to or after entering the IMD.
Medicaid will continue through the twelve (12) month postpartum period.
3. Eligibility for pregnancy-related Medicaid may be determined for the retroactive period
but not prior to October 1, 2019, which is the effective date of the IMD exception
provision.
C. Individuals age sixty-five (65) or older may not receive Medicaid benefits while in an IMD
unless they reside in a long-term care facility or receive inpatient hospital services and are
otherwise eligible for Medicaid in an allowed group.
