If any resident of a nursing facility or ICF/DD is admitted to such facility on the basis that the charges for such resident’s care will be paid from private funds, and the source of payment for such care thereafter changes from private funds to payments under this Article, the facility shall, upon receiving the first such payment under this Article, notify the Illinois Department of such source of private funds for such recipient and repay to the source of private funds any amounts received from such source as payment for care for which payment also was made under this Article. Private funds shall not include third party resources such as insurance or Medicare benefits or payments made by responsible relatives.
