"We are deeply concerned that [SSI] beneficiaries are receiving overpayment notices in error, because SSA is not following its own determination to exclude EIPs [stimulus checks] from countable resources. As you know, SSI benefits, while modest, have a substantial impact in the lives of the people who rely on them. Benefit suspensions and overpayment notices--regardless of the cause--can have a profound negative impact in their lives. Further, losing SSI eligibility risks a lengthy bureaucratic process to restore eligibility and also risks beneficiaries' access to Medicaid coverage."
