Southwest Orthopedic and Spine Hospital LLC doing business as OASIS Hospital, United Surgical Partners International Inc. (USPI), and Dignity/USP Phoenix Surgery Centers LLC, have agreed to pay $5.6 million to resolve alleged False Claims Act violations relating to improper financial relationships between OASIS and Southwest Orthopedic and Spine Hospital Physicians Group LLC (Southwest Physicians). OASIS is a surgical hospital located in Phoenix, Arizona. USPI disclosed the arrangements at issue to the government following a 2019 internal compliance review and independent investigation. The settlement resolves allegations that from 2011 through 2018 OASIS made improper financial contributions to Southwest Physicians, a physician group that referred patients to OASIS. Those financial contributions allegedly took the form of interest payments on convertible bonds issued to the physicians’ group. The United States alleged that these arrangements violated both the Anti-Kickback Statute (AKS) and the Physician Self-Referral Law, commonly known as the Stark Law.
