Any advance payment a defendant physician or his insurer makes to or for the plaintiff, or any other person, is not an admission of liability for injuries or damages the plaintiff or anyone else suffers as to a claim for malpractice. Evidence of an advance payment is not admissible in a court proceeding concerning malpractice until there is final determination in the plaintiff's favor, in which case the final amount payable shall be reduced by any advance payments.
