How to report Medicare and Medicaid fraud

U.S. Department of Health and Human Services, Office of Inspector General (HHS-OIG)

Deadline

There's no deadline to report suspected fraud to the OIG hotline itself; older conduct is still worth reporting. If you're weighing a qui tam suit instead, the False Claims Act's first-to-file rule means only the very first relator to file on a given set of facts can collect anything, so don't sit on strong evidence.

The OIG Hotline takes complaints online at tips.oig.hhs.gov or by phone at 1-800-HHS-TIPS, and you can report anonymously if you prefer; give the name of the provider or company involved, a full account of what happened, and any billing records you can attach. Calling the hotline alone pays you nothing, though a still-active CMS incentive program can pay up to $1,000 if your tip leads to a Medicare recovery of at least $100. The real money sits elsewhere: the same facts, filed instead as a qui tam lawsuit under the False Claims Act, can pay a relator 15% to 30% of what the government recovers, often far more than $1,000 on a case involving real billing fraud. Read our qui tam guide before you file anything with the hotline, since a lawyer needs to be involved from the start if you want to keep that option open.

What to gather first

  • The name and contact information of the provider, facility, or company you're reporting
  • A narrative describing what happened, when it happened, and how you found out
  • Billing records, medical records, Explanation of Benefits statements, or claim numbers that support your account
  • Contact information for anyone else who can corroborate the allegation

Report to the HHS-OIG hotline or call 1-800-447-8477

A reward may apply through the qui tam False Claims Act program.

After you report

  1. Your report is logged and an investigator reviews it. They may contact you for more detail or reach out to the provider or facility directly.
  2. Reporting here does not pay you on its own, but the same facts filed as a qui tam suit can pay a share of what the government recovers.
  3. You can usually ask to stay anonymous, and you do not need a lawyer to file the report itself.
