Section 3234 - [Multiple versions] Pre-existing condition provisions in group and blanket disability policies(a) Every group or blanket policy issued or issued for delivery in this state which provides benefits by reason of the disability of the insured and which includes a pre-existing condition provision shall contain in substance the following provision or provisions which in the opinion of the superintendent are more favorable to the members of the group: (1) In determining whether a pre-existing condition provision applies to an eligible person, the group or blanket disability policy shall credit the time the person was previously covered under a previous group or blanket disability insurance plan or policy or employer-provided disability benefit arrangement, if the previous coverage was continuous to a date not more than sixty days prior to the effective date of the new coverage. The credit shall apply to the extent that the previous coverage or level of benefits was substantially similar to the new coverage or level of benefits; and(2) No pre-existing condition provision shall exclude coverage for a period in excess of twelve months following the effective date of coverage for the covered person.(b) Nothing herein shall be construed to prohibit or restrict an insurer from utilizing other forms of underwriting for the members of the group in lieu of, or in addition to, the pre-existing condition provision described in subsection (a) of this section.
