WHAT ARE “1634” STATES?

States known as “1634” states are states that have completed a “1634 agreement” with the Social Security Administration. This agreement determines eligibility for a specific state’s Medicaid program for Supplemental Security Income (SSI) recipients. This is known as categorical eligibility. The agreements are only with states that use Supplemental Security Income (SSI) criteria to determine Medicaid eligibility. In other words, individuals who receive Supplemental Security Income (SSI) in those states receive Medicaid automatically. Individuals do not need to apply for Medicaid benefits separately.
