The OIG Hotline takes all allegations of fraud and abuse seriously. Providing your identity and contact information, however, could facilitate any subsequent investigation, as the agency assigned to review your complaint may have additional questions. OIG will exercise due caution to protect your identity, but we can provide no guarantees of this.
If you choose to remain anonymous, the best method to transmit your complaint would be via regular mail:
Office of the Inspector General
HHS TIPS Hotline
P.O. Box 23489
Washington, DC 20026
Please provide the following information. If you would like your referral to be submitted anonymously please indicate in your email or phone call (1-800-447-8477) that you wish to remain anonymous.
This is the information needed for all complaints:
You should check your Medicare Summary Notices carefully to verify that you received the services that Medicare paid for. If you do not recognize a particular service that does not necessarily mean that fraud has been committed. For example, it is possible that you received the service, but the provider name or service description is unfamiliar.
If you identify an erroneous charge on your Medicare Summary Notice, you should call the number listed in the Customer Service Box in order to speak with the Medicare-contracted insurance company that processed the claim. A representative will be able to access your records via computer, and may be able to determine immediately whether the service charge represents a billing error, a misunderstanding on your part, or a potential instance of fraud.
If you are unable to reach the Medicare contractor, or if so advised by the contractor representative, you may also report the charge to the Inspector General's Hotline at 1-800-HHS-TIPS (1-800-447-8477).
