Tennessee Code Title 56. Insurance § 56-5-206

If it is determined through the dispute resolution process set forth in the federal Fair Credit Reporting Act (15 U.S.C. § 1681i(a)(5)), that the credit information of a current insured was incorrect or incomplete and if the insurer receives notice of the determination from either the consumer reporting agency or from the insured, the insurer shall re-underwrite and re-rate the consumer within thirty (30) days of receiving the notice. After re-underwriting or re-rating the insured, the insurer shall make any adjustments necessary, consistent with its underwriting and rating guidelines. If an insurer determines that the insured has overpaid the premium, the insurer shall refund to the insured the amount of overpayment calculated back to the shorter of either the last twelve (12) months of coverage or the actual policy period.
