When States have elected Federal administration of their State supplementary payments
(SSPs), SSA uses the residency determination when making SSP eligibility and payment amount
As discussed more fully in SI 01715.010A.3., SSA also determines Medicaid eligibility for SSI recipients in the majority of
States. As part of this task, SSA determines the State and county responsible for
the recipient's Medicaid.
When there is no SSP or the SSP is State-administered the State/county of residence
for SSP purposes is the State/county of residence for Medicaid purposes. SSA field
offices (FOs) determine the State of residence even when there is no SSP or SSP is State-administered.
The residence determination is conveyed to the States by the State data exchange (SDX ). States use this information to administer several of their programs.
The State/county of residence determination is not used for any SSI program purpose.
For example, a determination as to a recipient's State/county of residence may not be used as part of the decision as to the excludability of a home to which the recipient
intends to return.
