Medicare: Concerns With Physicians at Teaching Hospitals (PATH) Audits

Pursuant to a congressional request, GAO reviewed the Physicians at Teaching Hospitals (PATH) initiative, focusing on: (1) whether the Department of Health and Human Services' (HHS) Office of the Inspector General (OIG) has a legal basis for conducting PATH audits; (2) whether the OIG has followed an acceptable approach and methodology in conducting the audits; and (3) the significance of the billing problems identified in selected audits.
