Tennessee Code Title 56. Insurance § 56-27-122

(a) The commissioner has the authority to suspend or cancel the license of any medical service corporation or any agent of the corporation for violation of this chapter or of the insurance laws that may apply that are not in conflict with this chapter, after proper legal notice and opportunity of hearing, and subject to judicial review. The commissioner has the authority, after the issuance of a certificate of authority, to withdraw approval that the commissioner may have previously granted of any document required to be filed with the department under any section of this chapter. Such authority includes the right to require a medical service plan corporation to solicit in a manner required by agents' licensing laws, and to fulfill contracts approved by the commissioner, to utilize soliciting methods provided by this chapter, or by other insurance laws, including the agents' licensing law applying to casualty companies, or to operate in a county or counties or area different from those on which the certificate of authority was based, and to comply with other orders and regulations of the commissioner or requirements of this chapter; provided, that the contracts and practices are in compliance with this chapter and are not violative of other laws of this state. The authorization shall be deemed to be an amendment to the original certificate of authority.

(b) The commissioner has the power and authority to revoke and amend, after reasonable notice and hearing, any certificate, order, authority or consent made by the commissioner to a medical service plan corporation, and may also cancel or suspend the authority of the corporation to transact business in any particular county or counties or area if the commissioner finds that less than fifty-one percent (51%) of the eligible licensed doctors of medicine practicing in that county are participating physicians.
