The Office will issue any reimbursement for equivalent benefits owed to the district with respect to the district having provided such individual or couple State or locally-funded assistance benefits to cover basic needs pending the individual's or couple's federal determination of eligibility for SSI benefits by first determining if the district has been fully reimbursed through the federal SSI IAR process for such interim assistance provided. If a deficit remains after the federal payment has been applied, or if there is no federal SSI IAR payment, the district shall be provided reimbursement from any retroactive SSP benefits or SSPNA, including benefits owed to a deceased individual eligible for SSP benefits or SSPNA prior to the date of death.
