Mississippi Code Title 43. Public Welfare § 43-13-5

The State Department of Public Welfare, after having made a determination with respect to eligibility with due regard to the resources and income of the applicant, may make vendor payments on behalf of eligible individuals for such care as may be authorized within the limits of available funds, provided that such medical or remedial care is rendered by or under the supervision of a licensed practitioner, and provided further that no regulation shall be promulgated which limits or abridges the recipient's free choice of the provider of medical and remedial care or service. Such recipients of medical assistance for the aged shall only be persons:

Medical assistance for the aged shall be payable under this article on behalf of any person who is a patient of an institution, public or private, where such payments are matchable under the provisions of the federal Social Security Act as amended and where such institution conforms to the requirements of the federal Social Security Act as amended and the applicable statutes of Mississippi.
