Nuvance Health, the parent company of Danbury Hospital, has warned that it may face bankruptcy if Connecticut does not approve its planned affiliation with Northwell Health, a New York-based hospital system. Nuvance, which has reported losses exceeding $220 million over the last two fiscal years, is seeking regulatory approval to form a $20 billion network with Northwell that would encompass 99,000 employees. A public hearing is scheduled for November 6th.
