Highest-Priority Cases

Inclusion on this list reflects a federal exclusion record and an active NPI registry entry — it does not confirm the physician is currently seeing patients. NPIs may remain active for billing, research, teaching, or administrative purposes. Full methodology

These physicians have the most concerning combination of serious offense, recent registry activity, and cross-state movement.

About these records

Every physician named on this page appears in an official government record — the HHS Office of Inspector General's List of Excluded Individuals/Entities (LEIE) or a state medical-board action — and is shown here as published by that agency. The basis for each exclusion is stated in the official record: some exclusions follow criminal convictions, others are administrative. Inclusion on this page asserts nothing beyond what the official record states, and an active provider registry entry does not confirm that a physician is currently seeing patients.

Different people can share the same name. Before drawing any conclusion about a specific individual, verify identity against the NPI number and the primary record at exclusions.oig.hhs.gov. If you believe a record shown here is inaccurate, outdated, or refers to a different person, email editor@thepublicledgers.org and we will review and correct it.

If you found your doctor on this page
  1. An active registry record does not confirm they are currently practicing.
  2. Check your state medical board for their current license status.
  3. Report concerns to the OIG Hotline: 1-800-HHS-TIPS.
