Tennessee Code Title 56. Insurance § 56-26-129

Every individual accident and health policy or contract shall have printed thereon or attached thereto a notice stating in substance that the person to whom the policy or contract is issued shall be permitted to return it within ten (10) days of its delivery to the purchaser and to have the premium paid by the purchaser refunded if, after examination of the policy or contract, the purchaser is not satisfied with it for any reason. If a policyholder or purchaser pursuant to the notice returns the policy or contract to the company at its home office or to the agent through whom it was purchased, it shall be void from the beginning and the parties shall be in the same position as if no policy or contract had been issued.
