resident's stay, except as prohibited by Titles XVIII and XIX of the federal Social Security Act. For purposes of this Section, "late payment" means non-receipt of payment after submission of a bill. If payment is not received within 45 days after submission of a bill, a facility may send a notice to the resident and responsible party requesting payment within 30 days. If payment is not received within such 30 days, the facility may thereupon institute transfer or discharge proceedings by sending a notice of transfer or discharge to the resident and responsible party by registered or certified mail. The notice shall state, in addition to the requirements of Section 3-403 of this Act, that the responsible party has the right to pay the amount of the bill in full up to the date the transfer or discharge is to be made and then the resident shall have the right to remain in the facility. Such payment shall terminate the transfer or discharge proceedings. This subsection does not apply to those residents whose care is provided for under the Illinois Public Aid Code. The Department shall adopt rules setting forth the criteria and procedures to be applied in cases of involuntary transfer or discharge permitted under this Section.
