The largest private hospital in Hawaii has agreed to pay $2.5 million to settle two lawsuits alleging the Honolulu based hospital overcharged Medicare, the state’s Medicaid program and TRICARE, a health benefits program for military dependents. The settlement has come after five years of negotiation between The Queen’s Medical Center and the government. Two whistleblowers, former employees, began the suit and were not identified in the settlement announcement. They will receive $400,000 out of the settlement for their involvement.

The suit alleged the hospital submitted false claims seeking payments for anti-psychotic medications which were prescribed by physicians without prior knowledge of a psychiatrist among other allegations. In addition to the payment, Queen’s entered a corporate integrity agreement with the U.S. Department of Health and Human Services, which will maintain a compliance program to assure the hospital billings are genuine.
