New Jersey Statutes Title 34. Labor and Workmen's Compensation 34 § 15-19

After an injury, the employee, if so requested by his employer, must submit himself for physical examination and X-ray at some reasonable time and place within this state, and as often as may be reasonably requested, to a physician or physicians authorized to practice under the laws of this state. If the employee requests, he shall be entitled to have a physician or physicians of his own selection present to participate in such examination. The refusal of the employee to submit to such examination shall deprive him of the right to compensation during the continuance of such refusal. When a right to compensation is thus suspended no compensation shall be payable in respect to the period of suspension. On request, the workmen's compensation bureau may examine the X-ray for the purpose of determining the amount of disability due, if any.
