If the group insurance policy from which conversion is made insures the employee or member for major medical expense insurance, the employee or member shall be entitled to obtain a converted policy providing catastrophic or major medical coverage under a plan meeting the following requirements:

(a) A maximum benefit at least equal to either, at the option of the insurer, (1) or (2) below:

(1) The smaller of the following amounts:

(A) The maximum benefit provided under the group policy.

(B) A maximum payment of $250,00 per covered person for all covered medical expenses incurred during the covered person's lifetime.

(2) The smaller of the following amounts:

(A) The maximum benefit provided under the group policy.

(B) A maximum payment of $250,000 for each unrelated injury or sickness.

(b) Payment of benefits at the rate of eighty percent of covered medical expenses which are in excess of the deductible, until twenty percent of such expenses in a benefit period reaches $1,000, after which benefits will be paid at the rate of one hundred percent during the remainder of such benefit period. Payment of benefits for outpatient treatment of mental illness, if provided in the converted policy, may be at a lesser rate but not less than fifty percent.

(c) A deductible for each benefit period which, at the option of the insurer, shall be (1) the sum of the benefits deductible and $100, or (2) the corresponding deductible in the group policy. The term "benefits deductible," as used herein, means the value of any benefits provided on an expense incurred basis which are provided with respect to covered medical expenses by any other hospital, surgical, or medical insurance policy or hospital or medical service subscriber contract or medical practice or other prepayment plan, or any other plan or program whether on an insured or uninsured basis, or in accordance with the requirements of any state or federal law and, if pursuant to section eleven of this article, the converted policy provides both basic hospital or surgical coverage and major medical coverage, the value of such basic benefits.

If the maximum benefit is determined by (a) (2) above, the insurer may require that the deductible be satisfied during a period of not less than three months if the deductible is $100 or less, and not less than six months if the deductible exceeds $100.

(d) The benefit period shall be each calendar year when the maximum benefit is determined by (a) (1) above or twenty-four months when the maximum benefit is determined by (a) (2) above.

(e) The term "covered medical expenses," as used above, shall include at least, in the case of hospital room and board charges, the lesser of the dollar amount in Plan A and the average semiprivate room and board rate for the hospital in which the individual is confined and twice such amount for charges in an intensive care unit. Any surgical schedule shall be consistent with those customarily offered by the insurer under group or individual health insurance policies and must provide at least a $1,200 maximum benefit.
