Stung by a $20.5 million verdict stemming from the death of a patient at the Emory Sleep Center, Emory University is suing the independent contractor that operated the center to recoup damages and the legal costs Emory incurred while defending the case.

Emory—which operates Emory University Hospital, The Emory Clinic and the Sleep Center—filed suit May 12 against Boston-based Neurocare Inc. in federal court in Atlanta, claiming that Neurocare had defaulted on contractual promises to indemnify and defend the hospital and clinic against negligence claims and to carry at least $1 million in professional liability insurance for the sleep center’s medical director, an Emory physician.
