据报道，司法部 (DOJ) 正在对美国最大的健康保险公司、药品福利和医生团体的高级管理人员联合健康集团 (UnitedHealth Group) 发起反垄断调查。 The Justice Department (DOJ) is reportedly launching an antitrust investigation into UnitedHealth Group, the largest US health insurer and a top manager of pharmacy benefits and physician groups. 此次调查的重点是 UnitedHealthcare 和 Optum Health 之间的关系，UnitedHealthcare 是该公司旗下覆盖约 5000 万人的保险部门，而 Optum Health 则拥有约 90,000 名医生。 The investigation is focused on the relationship between UnitedHealthcare, the company's insurance division covering roughly 50 million people, and Optum Health, which employs about 90,000 doctors. 调查人员正在调查 UnitedHealthcare 在承包实践中是否偏袒 Optum 旗下的集团，以及 Optum 对医疗保健提供者的所有权是否对竞争对手构成了挑战。 Investigators are examining whether UnitedHealthcare favored Optum-owned groups in contracting practices and whether Optum's ownership of healthcare providers presented challenges to rivals.
