Talks have resumed between Humana officials and a University of Louisville doctors group in hopes of settling their contract dispute. The stalemate has dragged on for nine months.A brief statement from Humana says there have been recent, productive discussions and that the insurer and doctors hope to settle their contract dispute soon.The physicians’ previous contract expired last June 30, with the two sides unable to come to terms on reimbursement rates. The group, called U of L Physicians, includes more than 550 doctors in 78 areas of medicine. The stalemate has meant higher, out-of-network costs for many patients under the care of the U of L doctors.Neither side is saying much else about how the talks are going. The doctors group says it’s committed to finding a solution to the impasse.
