53-1-409. Limitations on liability of resident or financially responsible person for cost of care. (1) The resident or financially responsible person is liable only for the cost of care that the department has determined that the person is able to pay and for which the department has billed the resident or financially responsible person. If the amount payable is retroactively reduced because of a new determination of ability to pay, the resident or financially responsible person shall pay only the reduced amount for the period of time covered by the retroactive reduction.
(2) The natural or adoptive parents of a long-term resident may not be required to pay for the resident's cost of care in an amount exceeding the cost of caring for a normal child at home as determined and updated annually by the department based upon the annual cost of raising a child, as estimated by the United States department of agriculture.
(3) The natural or adoptive parents of a long-term resident may not be required to pay for the resident's cost of care for periods after the resident attains 18 years of age.
(4) This section may not be construed to reduce the liability of a third party for a resident's full cost of care as provided in this part.
