UnitedHealthcare can't seem to get along with anyone these days. The insurer has warned some patients that it might not be able to negotiate a contract with Tennessee-based Sumner Regional Medical Center before the September 30th deadline. And there's a twist: Sumner Regional employees have UnitedHealthcare coverage, which means if the contract isn't renegotiated, hospital employees will have to receive non-emergency care at another in-network facility. This is only the latest in a series of contract disputes.

United Healthcare says HCA is charging the insurer too much for its services; HCA disagrees, saying it just wants a fair level of reimbursement. Report [2]
