(c) No self-insured employee welfare benefit plan which provides maternity benefits for a person covered continuously from conception shall be issued, amended, delivered, or renewed in this state on or after July 1, 1976, if it contains any exclusion, reduction, or other limitations as to coverage, deductibles, or coinsurance provisions as to involuntary complications of pregnancy, unless those provisions apply generally to all benefits paid under the plan. If a fixed amount is specified in the plan for surgery, the fixed amounts for surgical procedures involving involuntary complications of pregnancy shall be commensurate with other fixed amounts payable for procedures of comparable difficulty and severity. In a case where a fixed amount is payable for maternity benefits, involuntary complications of pregnancy shall be deemed an illness and entitled to benefits otherwise provided by the plan. Where the plan contains a maternity deductible, the maternity deductible shall apply only to expenses resulting from normal delivery and cesarean section delivery. However, expenses for cesarean section delivery in excess of the deductible shall be treated as expenses for any other illness under the plan. This subdivision shall apply to all self-insured employee welfare benefit plans except any plan made subject to an applicable collective bargaining agreement in effect before July 1, 1976. For purposes of this subdivision, involuntary complications of pregnancy shall include, but not be limited to, puerperal infection, eclampsia, cesarean section delivery, ectopic pregnancy, and toxemia.
All plans subject to this subdivision and issued, amended, delivered, or renewed in this state on or after July 1, 1976, shall be construed to be in compliance with this section, and any provision in any plan which is in conflict with this section shall be of no force or effect.
