(a) A patient who receives services under this article shall, by accepting such services, be deemed to have agreed to:

(1) Be liable to any county which pays all or any part of that patient's cost of care for the entire amount so paid by that county, except that a patient who meets the indigency standards based upon 100 to 125 percent of the federal poverty level shall be liable for an amount which is the greater of $100.00 or the reasonable percentage of costs for which the patient is liable under subsection (a) of Code Section 31-8-43 and a patient who meets the indigency standards based upon less than 100 percent of the federal poverty level shall be liable for $100.00 of those costs, but liability under this subsection shall never exceed the county's payments for cost of care;

(2) Have made an assignment to that county paying any part of that patient's cost of care for any benefits for such care for which the patient is eligible from a third party up to the amount actually paid and cooperate with the county in obtaining any such benefits to repay the county;

(3) Cooperate with any county paying any part of that patient's cost of care in identifying the father of a child delivered to the patient by a hospital acting in compliance with this article and in seeking to obtain from such father repayment of that portion of the county's payment which, under the indigency standards, that father is able to repay; and

(4) Cooperate with any county paying any part of that patient's cost of care in applying and qualifying for the medical assistance program for the needy under Title XIX of the Social Security Act or any other federal, state, or local governmental program for which the patient may be eligible.

(b) The failure of a patient to cooperate as required by paragraphs (2), (3), and (4) of subsection (a) of this Code section shall render the patient and any person liable for other expenses of the patient, including but not limited to the parents of a minor patient and the spouse of a patient, liable to the county for all payments which that county makes for the patient's cost of care. Failure of a patient to cooperate as required by paragraphs (2), (3), and (4) of subsection (a) of this Code section shall not be a valid ground to deny the patient services otherwise required to be provided under this article unless the patient at the time of admission refuses to sign a document, in such form as the commissioner shall prescribe and provide, acknowledging notification that the patient's receiving services shall constitute an agreement to the terms of paragraphs (1) through (4) of subsection (a) of this Code section unless waived by the county health care advisory officer.

(c) Except as provided in subsection (b) of this Code section, the father of a patient's child who is delivered by a hospital as required by this article and any other person legally responsible for other expenses of the patient shall be liable to the county which pays the patient's cost of care to the same extent the patient is liable therefor under paragraph (1) of subsection (a) of this Code section. This obligation to make repayment shall be in addition to any other obligation imposed by law.

(d) The county may bring a civil action to recover, from any person liable therefor under this Code section, those payments which the county has made for a patient's cost of care to the extent of the liability imposed by this Code section but in no event may recover more than the county paid for such costs of care.

(e) A county or any person aggrieved by any determination under this article that such county or person is liable for a patient's cost of care may bring a de novo civil action in superior court challenging that determination.
