All noninstitutionalized married couples who are eligible for supplemental security income (SSI) are treated as separate individuals for determining eligibility and benefit amounts, beginning the month after the month they begin living apart. In the case of an initial application or reinstatement following a period of ineligibility, each member of a married couple not living together is considered an individual as of the date of application or request for reinstatement, regardless of when the separation occurred. See Title 8, Chapter 281, Medicaid Eligibility - Institutional Care (Categories 081, 083 and 084), for information on separation caused by the institutionalization of one member of a married couple.
