Middletown, CT-based Middlesex Hospital will not accept insurance from Anthem Blue Cross Blue Shield members as of May 1 unless a new agreement is reached. In recent days, negotiations over terms and conditions of reimbursement have broken down. After May 1, Blue Cross Blue Shield members will be turned away from Middlesex, unless they seek care in the emergency room. Anthem Blue Cross Blue Shield is the state's largest provider of health insurance. Members of the insurer's point-of-service plans would be covered on an out-of-network basis, but would be required to pay a larger percentage of their medical bills. Article
