Report Medicare Fraud

If you see something, say something. Medicare fraud costs taxpayers over $100 billion per year. Your report could help recover millions — and you may be entitled to a reward.

How to Report: Step by Step

Follow these steps to file an effective fraud report

1

Gather Your Evidence

Collect everything you can before reaching out. The more detail, the better the investigation.

2

Choose Your Reporting Channel

Call the OIG hotline (1-800-HHS-TIPS), submit online at OIG.HHS.gov, or email HHSTips@oig.hhs.gov. For whistleblower rewards, consult a False Claims Act attorney first.

3

File Your Report

Provide the provider name, NPI, dates, locations, and a clear description of what happened. Include any supporting documents.

4

Follow Up

Save your reference number. You may be contacted for additional information. Anonymous reports are accepted but named reports lead to better outcomes.

What Happens After You Report

📥

Intake & Review

Your report is logged and reviewed by OIG analysts. They assess whether the complaint warrants further investigation.

🔍

Investigation

If warranted, investigators examine billing records, interview witnesses, and subpoena documents. This can take months to years.

⚖️

Legal Action

Cases may result in civil settlements, criminal charges, or exclusion from Medicare. The DOJ recovered $2.2B in healthcare fraud in FY2023.

🛡️

Whistleblower Protection

Federal law protects you from retaliation. If your employer fires you for reporting fraud, you may have a wrongful termination claim.

💰 Whistleblower Rewards: The False Claims Act

Under the federal False Claims Act (also called "qui tam"), private citizens who report fraud against the government can receive 15–30% of the total amount recovered. In major Medicare fraud cases, this can mean millions of dollars.

How It Works

  1. File under seal. You (the "relator") file a sealed complaint in federal court with evidence of fraud. You'll need a qui tam attorney.
  2. DOJ investigates. The government has 60 days (often extended) to decide whether to join your case.
  3. Government joins → 15–25%. If the DOJ takes the case and recovers funds, you receive 15–25% of the recovery.
  4. Government declines → 25–30%. If you continue alone and win, you receive 25–30%.
⚠️

Important: Qui tam cases require an attorney experienced in False Claims Act litigation. The complaint must be filed under seal — do not publicly disclose the fraud before filing. Many healthcare fraud attorneys work on contingency (no upfront cost).

What Counts as Medicare Fraud?

📈

Upcoding

Billing for a more expensive service than was actually provided (e.g., 99214 instead of 99213).

👻

Phantom Billing

Billing for services, procedures, or supplies that were never provided to the patient.

🏥

Unnecessary Services

Ordering tests, procedures, or treatments that are not medically necessary.

💵

Kickbacks

Receiving or paying for patient referrals — illegal under the Anti-Kickback Statute.

🔄

Unbundling

Billing separately for services that should be billed as a package at a lower rate.

👤

Identity Theft

Using someone else's Medicare number to bill for services.
