of this Act, and during all subsequent open enrollment periods, a health plan that has enrollees terminate their coverage in order to enroll in other health plans shall be responsible for financing 75 percent of the health benefits administered to such enrollees under the other plans and shall receive 75 percent of the premiums paid for such enrollees' coverage under such other health plans for the first 3 months of coverage in the new plan year. 106. State flexibility in ensuring orderly health insurance market outside of an Exchange (a) In general With respect to health insurance coverage offered in a State, the State may, in consultation with the Secretary, take such steps, such as limiting the availability of general open enrollment periods, imposing delays in the effectiveness for coverage, permitting differentials in premiums based on age and other factors, as the State determines necessary in order to ensure an orderly market for health insurance coverage in the State that is not offered through an Exchange. Such steps may include the establishment of an initial open enrollment period during which qualified residents may enroll in health insurance coverage without the imposition of any underwriting as the State determines to be appropriate in ensuring initial access to such coverage. (b) Flexibility in imposing additional requirements Nothing in this section shall be construed as preventing a State from continuing to apply, to health insurance coverage issued in the State, requirements under the provisions of title XXVII of the Public Health Service Act (as amended by subtitles A and C of title I of PPACA), that are not continued under section 101(b). (c) State flexibility with respect to Exchanges A State may waive such provisions of part 2 of subtitle D of title I of PPACA, in relation to the establishment of an Exchange in such State, as the State determines appropriate in order for the State to implement and administer a market-based system for the availability of health insurance coverage throughout
