A doctor of chiropractic who is the subject of an investigation by or on behalf of the board shall cooperate fully with the investigation. Cooperation includes appearing at conferences, meetings, or hearings scheduled by the board and for which the board provided notice in accordance with chapter 14; responding fully and promptly to any question raised by or on behalf of the board relating to the subject of the investigation; and providing copies of patient health records, as reasonably requested by the board, to assist the board in its investigation. If the board does not have written consent from a patient allowing the board access to the patient’s health records, a doctor of chiropractic shall delete any data in the record which identifies the patient before providing the records to the board.
