(c) An issuer of Medicare supplement policies and certificates shall file annually its rates, rating schedule, and supporting documentation including ratios of incurred losses to earned premiums by policy duration for approval by the commissioner in accordance with the filing requirements and procedures prescribed by the commissioner and this code. The supporting documentation shall also demonstrate in accordance with actuarial standards of practice using reasonable assumptions that the appropriate loss ratio standards can be expected to be met over the entire period for which rates are computed. The demonstration shall exclude active life reserves. An expected third-year loss ratio that is greater than or equal to the applicable percentage shall be demonstrated for policies or certificates in force less than three years. As soon as practicable, but prior to the effective date of enhancements in Medicare benefits, every issuer of Medicare supplement policies or certificates shall file with the commissioner, in accordance with applicable filing procedures, all of the following:
(1)(A) Appropriate premium adjustments necessary to produce loss ratios as anticipated for the current premium for the applicable policies or certificates. The supporting documents necessary to justify the adjustment shall accompany the filing.(B) An issuer shall make premium adjustments necessary to produce an expected loss ratio under the policy or certificate to conform to minimum loss ratio standards for Medicare supplement policies and that are expected to result in a loss ratio at least as great as that originally anticipated in the rates used to produce current premiums by the issuer for the Medicare supplement policies or certificates. No premium adjustment that would modify the loss ratio experience under the policy other than the adjustments described in this section shall be made with respect to a policy at any time other than upon its renewal date or anniversary date.(C) If an issuer fails to make premium adjustments acceptable to the commissioner, the commissioner may order premium adjustments, refunds, or premium credits deemed necessary to achieve the loss ratio required by this section.(2) Any appropriate riders, endorsements, or policy forms needed to accomplish the Medicare supplement policy or certificate modifications necessary to eliminate benefit duplications with Medicare. The riders, endorsements, or policy forms shall provide a clear description of the Medicare supplement benefits provided by the policy or certificate.
