(a) Any advance payment made by a defendant health care provider or the provider's insurer to or for a plaintiff or any other person shall not be construed as an admission of liability for injuries or damages suffered by the plaintiff or anyone else in an action brought for health care medical negligence.
(b) Evidence of an advance payment shall not be admissible unless there is a final judgment in favor of the plaintiff, in which event the Court shall reduce the judgment to the plaintiff to the extent of the advance payment. The advance payment shall inure to the exclusive credit of the defendant or the defendant's insurer making the payment. In the event the advance payment exceeds the liability of the defendant or the insurer making it, the Court shall order any adjustment necessary to equalize the amount which each defendant is obligated to pay, exclusive of costs. In no case shall an advance payment in excess of an award be repayable by the person receiving it.
