A licensee who is the subject of an investigation by or on behalf of a board shall cooperate fully with the investigation. Cooperation includes 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 client records, as reasonably requested by the board, to assist the board in its investigation. The board shall pay for copies requested. If the board does not have a written consent from a client permitting access to the client's records, the licensee shall delete any data in the record that identifies the client before providing it to the board. The board shall maintain any records obtained pursuant to this section as investigative data pursuant to chapter 13.
