Daniel R. Levinson, the HHS Inspector General, has posted an open letter to health care providers regarding the self-disclosure protocol. The letter discusses what needs to be in the initial submission, stresses the need to respond quickly to OIG requests for additional information, and reiterates that the self-disclosure process should be used when a provider believes the conduct may constitute fraud, and not for mere billing errors. Mr. Levinson also indicates that OIG will not require a provider to enter into a Corporate Integrity Agreement or Certification of Compliance Agreement if it follows the self-disclosure process outlined in the letter.
