1. The medical society of the county in which the physician's office is located at the time or a board designated by such county society or a board representing duly licensed physicians of any other school of medical practice in such county shall investigate, hear and make findings with respect to all charges as to professional or other misconduct of any authorized physician as herein provided under rules and procedure to be prescribed by the medical appeals unit, and shall report evidence of such misconduct, with their findings and recommendation with respect thereto, to the chair. Failure to commence such investigation within sixty days from the date the charges are referred to the society by the chair or submit findings and recommendations relating to the charges within one hundred eighty days from the date the charges are referred shall empower the chair to appoint, as a hearing officer, a member of the board, employee, or other qualified hearing officer to hear and report on the charges to the chair. A qualified hearing officer, who is neither a member of the board, or employee thereof shall be paid at a reasonable per diem rate to be fixed by the chair. Such investigation, hearing, findings, recommendation and report may be made by the society or board of an adjoining county upon the request of the medical society of the county in which the alleged misconduct or infraction of this chapter occurred, subject to the time limit and conditions set forth herein. The medical appeals unit shall review the findings and recommendation of such medical society or board, or hearing officer appointed by the chair upon application of the accused physician and may reopen the matter and receive further evidence. The findings, decision and recommendation of such society, board or hearing officer appointed by the chair or medical appeals unit shall be advisory to the chair only, and shall not be binding or conclusive upon him or her.
