The members shall serve for terms of four years and until their successors are appointed and qualify, except that initial terms of two practitioners, the consumer member, and one physician, are for two years. Vacancies must be filled in the manner of the original appointment for the unexpired portion of a term. The board, after notice and opportunity for hearing, may remove any member of the committee for neglect of duty, incompetence, revocation or suspension of certification, or other dishonorable conduct. Members of the committee shall receive mileage, subsistence, and per diem provided by law for members of state boards, commissions, and committees for each meeting attended. No member may serve more than one full four-year term consecutively, but he is eligible for reappointment two years from the date the full four-year term expires.
