Tennessee Code Title 56. Insurance § 56-7-3118

(a) Each contract between a covered entity or pharmacy benefits manager and a pharmacist or pharmacy must be mutually agreed upon and must outline the terms and conditions for the provision of pharmacy services.

(b) A covered entity or pharmacy benefits manager shall not cause or knowingly permit the use of any advertisement, promotion, solicitation, representation, proposal, or offer that is untrue, deceptive, or misleading.

(c) Removal of a pharmacy or a pharmacist from the network of a covered entity or pharmacy benefits manager does not release the covered entity or pharmacy benefits manager from the obligation to make any payment due to the pharmacy or pharmacist for services that have been properly rendered prior to the pharmacy being removed from the network. Properly rendered services do not include any services related to a fraudulent claim or intentional misrepresentation.

(d) A covered entity or pharmacy benefits manager shall not engage in a pattern or practice of reimbursing pharmacies or pharmacists in this state less than the amount that the pharmacy benefits manager reimburses a pharmacy benefits manager affiliate for providing the same drug or dispensed product or service.
