A big shout out to Matthew Margolis of Margolis Weldon LLC for this helpful information:
Stimulus Checks do not count as income for Medicaid beneficiaries or applicants and, therefore, do not disqualify them from Medicaid benefits including nursing home care. However, the money received from stimulus checks should be spent within 12 months because it will be counted as an asset, potentially impacting eligibility in the next year.
