(Identical to Mass.R.Civ.P. 35)
(a) Order for Examination. When the mental or physical condition (including the blood group) of a party, or of a person in the custody or under the legal control of a party, is in controversy, the court in which the action is pending may order the party to submit to a physical or mental examination by a physician or to produce for examination the person in his custody or legal control. The order may be made only on motion for good cause shown and upon notice to the person to be examined and to all parties and shall specify the time, place, manner, conditions, and scope of the examination and the person or persons by whom it is to be made.
(b) Report of Examining Physician.
(1) If requested by the party against whom an order is made under Rule 35(a) or 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, including results of all tests made, diagnoses and conclusions, together with like reports of all earlier examinations of the same condition. After delivery the party causing the examination shall be entitled upon request to receive from the party against whom the order is made a like report of any examination, previously or thereafter made, of the same condition, unless, in the case of a report of examination of a person not a party, the party shows that he is unable to obtain it. The court on motion may make an order against a party requiring delivery of a report 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 the trial.
(2) 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; but he does not otherwise waive his right to object at the trial to the introduction into evidence of the report or any part thereof.
(3) This subdivision applies to examinations made by agreement of the parties, unless the agreement expressly provides otherwise. This subdivision does not preclude discovery of a report of an examining physician or the taking of a deposition of the physician in accordance with the provisions of any other rule.

Plain-English Summary

Rule 35 is identical to its civil counterpart and the source says so before subsection (a). In the Probate and Family Court it is the route to an examination where a parent's or child's condition is genuinely at issue.

The order

Where the mental or physical condition — including the blood group — of a party, or of a person in the custody or under the legal control of a party, is in controversy, the court may order the party to submit to an examination by a physician, or to produce the person in their custody or legal control.

Four requirements sit on that. The order comes only on motion; only for good cause shown; only on notice to the person to be examined and to all parties; and it must specify the time, place, manner, conditions and scope of the examination and who is to conduct it. An order that leaves any of those open is not what the rule provides for.

The report, and the price of asking for it

Subsection (b)(1) gives the examined person or the party against whom the order was made a right, on request, to a detailed written report of the examining physician — findings, results of all tests, diagnoses and conclusions — together with like reports of all earlier examinations of the same condition. Once delivered, the party who caused the examination is entitled on request to a like report of any examination of the same condition, before or after, unless the party shows it cannot be obtained for a non-party. If a physician fails or refuses to make a report, the court may exclude that physician's testimony.

Subsection (b)(2) is the trap. By requesting and obtaining the report, or by deposing the examiner, the party examined waives any privilege regarding the testimony of every other person who has examined or may examine them about the same condition — in that action and in any other involving the same controversy. The waiver does not extend to objecting at trial to the report itself coming into evidence.

Subsection (b)(3) applies the whole of subsection (b) to examinations made by agreement of the parties unless the agreement expressly provides otherwise — so a stipulated examination carries the same waiver unless the parties say it does not.
