(a) If requested by the person examined, the party causing the examination to be made shall deliver to him a copy of a detailed written report of the examining physician setting out his findings. After such request and delivery, the party causing the examination to be made shall be entitled upon request to receive from the party examined a like report of any examination, previously or thereafter made, of the same mental or physical condition. If the party examined refuses to deliver said report, the court on motion duly served may make an order requiring delivery on such terms as are just, and if a physician fails or refuses to make a report the court may exclude his testimony if offered at trial.(b) By requesting and obtaining a report of the examination so ordered or by taking the deposition of the examiner, the party examined waives any privilege he may have in that action or any other involving the same controversy, regarding the testimony of every other person who has examined or may thereafter examine him in respect of the same mental or physical condition.
