⚠️ Important Context
All data on this page comes from publicly available CMS Medicare payment records. Unusual billing patterns may reflect legitimate medical practices (such as high-volume drug administration where each unit is counted as a separate service), data reporting differences, or group practice billing. Inclusion on this page does not constitute an accusation of fraud or wrongdoing. Only law enforcement and regulatory agencies can determine whether billing patterns represent fraud. Providers flagged by our statistical model have billing patterns similar to previously convicted providers, but many may have perfectly legitimate explanations.
We calculated services per working day for every provider in Medicare and flagged 4,636 providers with physically impossible billing volumes.
Disclaimer: High service volumes can have legitimate explanations (e.g., lab-like operations under an individual NPI, group practices billing under one provider). These are statistical flags, not accusations of fraud. Report suspected fraud: 1-800-HHS-TIPS.
