If the director shall for any reason have cause to believe that any violation of sections 354.400 to 354.636 has occurred or is about to occur, the director may give notice to the health maintenance organization and to the representatives, or other persons who appear to be involved in such suspected violation, to arrange a conference with the alleged violators, or potential violators, or their authorized representatives, for the purpose of attempting to ascertain the facts relating to such suspected or potential violation, and, in the event it appears that any violation has occurred or is about to occur, to arrive at an adequate and effective means of correcting or preventing such violation. Proceedings under this subsection shall not be governed by any formal procedural requirements, and may be conducted in such manner as the director may deem appropriate under the circumstances.
