The Minister for Government Services is responsible for administering the Human Services (Medicare) Act 1973, except to the extent that it is administered by the Minister for Health.

Part IID of that Act gives the Chief Executive Medicare certain powers to investigate whether civil or criminal offences have been committed in relation to health programs that the department delivers. Section 42 of the Act requires the department to report on the use of particular investigative powers. In 2018–19, one section 8P notice was issued.
