Which NPDB query source category includes agencies or contractors administering federal health care programs?

• A. Hospitals
• B. Private practice groups
• C. Agencies or contractors administering federal health care programs
• D. Public health departments

Answer: (C)

Understanding NPDB query source categories helps credentialing staff know where information comes from. The category for agencies or contractors administering federal health care programs is specifically designed for entities that run or contract federal programs like Medicare and Medicaid. These federal program administrators submit NPDB reports about actions affecting practitioners within those programs, so this category is the one that encompasses those agencies or contractors themselves. Hospitals, private practice groups, and public health departments are separate sources tied to clinical or public health settings, not the federal program administrators.
