When an individual residing in a section 1634 State has a Medicaid trust, SSA determines
            if the trust is countable for SSI purposes. The existence of a Medicaid trust results
            in a referral to the Medicaid State agency for a Medicaid eligibility decision. See
            SI 01730.048 for the definition of Medicaid trusts and procedures to determine if a trust is countable
            for SSI purposes.
         
         In the Boston Region, the section 1634 States are Maine, Massachusetts, Rhode Island,
            and Vermont.
