Next is the practice management business. We discuss the U.S. Oncology Network quite often. This organization supports more than 1,400 physicians across 450 sites of service. We provide a unique value proposition, which allows the physician to remain independent while utilizing McKesson services and staff to ensure the practice is running efficiently and effectively. This allows the physician to focus his or her time on treating patients. McKesson has 15 practices in the U.S. Oncology Network that are participating in the Oncology Care Model or OCM. The Centers for Medicaid and Medicaid Innovation recently released results for the fourth performance period related to the OCM. I'm pleased to report that all 15 practices earned high marks for quality performance. The practices improved care and provided an enhanced patient experience and also saved Medicare approximately $35 million during the performance period as compared to the established benchmark.
