The Investigations Division  protects the integrity of HHS programs through investigations of employee misconduct, contract and recipient fraud, waste, and abuse; to include, but not limited to bribery, theft, and egregious acts against the HHS system and programs. It also analyzes trends and patterns of behavior, and refers cases for Administrative Disqualification Hearings and prosecution to appropriate state or federal regulatory and law enforcement authorities. Additionally, the Investigations Division conducts personnel investigations at the State Supported Living Centers and State Hospitals, as well as within the HHS system.

The Investigations Division has four directorates: General Investigations; Law Enforcement; Internal Affairs; and Training. The division also has a Major Case Unit.
