Omnicare loses court dispute with UnitedHealth

Omnicare Inc. came out on the short end of a dispute with UnitedHealth Group, which it claims has cost it millions of dollars in lost reimbursement. The U.S. District Court for Northern Illinois granted a summary judgment in favor of UnitedHealth. Omnicare sued UnitedHealth, PacifiCare Health Systems Inc. and RxSolutions Inc. in 2006 , claiming the health insurer and its subsidiaries conspired to cheat the company out of Medicare Part D reimbursement.
