Mich. Comp. Laws § 500.3152
If requested by a person examined, a party causing an examination to be made shall deliver to him a copy of every written report concerning the examination rendered by an examining physician, at least 1 of which reports shall set out his findings and conclusions in detail. After such request and delivery, the party causing the examination to be made is entitled upon request to receive from the person examined every written report available to him or his representative concerning any examination relevant to the claim, previously or thereafter made, of the same mental or physical condition, and the names and addresses of physicians and medical care facilities rendering diagnoses or treatment in regard to the injury or to a relevant past injury, and shall authorize the insurer to inspect and copy records of physicians, hospitals, clinics or other medical facilities relevant to the claim. By requesting and obtaining a report of the examination so ordered or by taking the deposition of the examiner, the person examined waives any privilege he may have, in relation to the claim for benefits, regarding the testimony of every other person who has examined or may thereafter examine him in respect of the same mental or physical condition.
