If it is determined through the reinvestigation process set forth in the federal Fair Credit Reporting Act, 15 U.S.C. § 1681i(a)(5), that credit information relied upon by an insurer was incorrect, and if an insurer receives notice of that determination from either the consumer-reporting agency or from the insured who has provided written documentation from the consumer-reporting agency, within one year of the date after the insured is no longer a customer of the insurer, such insurer shall reunderwrite and rerate the consumer within 30 days after receiving the notice. After reunderwriting or rerating 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. (Added 2005, No. 211 (Adj. Sess.), § 5.)
