(a) The commissioner shall issue reasonable regulations to establish specific standards for policy provisions of Medicare supplement policies and certificates. The standards shall be in addition to and in accordance with applicable laws of this state, including Article 1 and Chapter 20. No requirement of this title relating to minimum required policy benefits, other than the minimum standards contained in this article, shall apply to Medicare supplement policies and certificates. The standards may cover but shall not be limited to the following:
(1) Terms of renewability.
(2) Initial and subsequent conditions of eligibility.
(3) Nonduplication of coverage.
(4) Probationary periods.
(5) Benefit limitations, exceptions, and reductions.
(6) Elimination periods.
(7) Requirements for replacement.
(8) Recurrent conditions.
(9) Definition of terms.
(b) The commissioner may issue reasonable regulations that specify prohibited policy provisions not otherwise specifically authorized by statute which, in the opinion of the commissioner, are unjust, unfair, or unfairly discriminatory to any person insured or proposed to be insured under a Medicare supplement policy or certificate.
(c) Notwithstanding any other provisions of law of this state, a Medicare supplement policy shall not exclude or limit benefits for loss incurred more than six months from the effective date of coverage because it involved a preexisting condition. The policy may not define a preexisting condition more restrictively than a condition for which medical advice was given or treatment was recommended by or received from a physician within six months before the effective date of coverage.
(d) No Medicare supplement policy or certificate in force in the state shall contain benefits that duplicate benefits provided by Medicare.
