(a)
(1) After a health maintenance organization has been in operation twenty-four (24) months, it shall have an annual open enrollment period of at least one (1) month during which it accepts enrollees up to the limits of its capacity, as determined by the health maintenance organization, in the order in which they apply for enrollment.
(2) A health maintenance organization may apply to the Insurance Commissioner for authorization to impose such underwriting restrictions upon enrollment as are necessary to preserve its financial stability, to prevent excessive adverse selection by prospective enrollees, or to avoid unreasonably high or unmarketable charges for enrollee coverage for healthcare services.
(3) The commissioner shall approve or deny the application within sixty (60) days of its receipt from the health maintenance organization.
(b) Health maintenance organizations providing or arranging for services on a group contract basis may limit the open enrollment provided for in subsection (a) of this section to all members of the groups covered by the contracts.
