In Lester v. S. J. Alexander, Inc., 127 Ga. App. 470 (193 SE2d 860) (1972), the Court found that the trial court properly excluded medical bills because no evidence was presented to differentiate between expenses directly related to the treatment of plaintiff's injuries from an automobile collision and those connected with the treatment of an unrelated kidney ailment. In upholding the trial court, we reasoned that the evidence was inadmissible both because no showing had been made that the "expenses were incurred in connection with the treatment of the injury, disease or disability," caused by the tort, and under the "rule that testimony offered as a whole without separating the relevant from that which is irrelevant and inadmissible is to be repelled in its entirety." Lester, 127 Ga. App. at 472 (1).
