"The pending demise of Health Republic, the largest of the nonprofit cooperatives created under the Affordable Care Act and the only co-op in New York, removes a significant player from the state's insurance industry. It also left the insurers' 215,000 members, about half of whom are individuals and half are insured through small businesses, in need of new coverage. Individual Health Republic plans will end on Dec. 31, and small-group plans end as early as Oct. 31, although some will continue into next year."
