The county of residence shall make payments for the care and treatment of any indigent person voluntarily admitted to the South Dakota Human Services Center the same as if there had been a regular commitment pursuant to chapter 27A-10 if such person is entitled to poor relief pursuant to chapter 28-13 and if such payments are based upon a statement by the administrator of the South Dakota Human Services Center that it would be in the best interests of such person that such person be kept at such hospital. In the event of a dispute as to a patient's residency, no payments made by any county constitute an admission that a patient has a residency within such county.
