Federal program recordOn the HHS-OIG exclusion list (LEIE).
According to the U.S. Department of Health and Human Services Office of Inspector General (HHS-OIG), Dr. William Hampton M.D. appears on the List of Excluded Individuals and Entities (LEIE) as published in the June 2026 edition of that list. The LEIE is the federal record of parties whose exclusion from billing Medicare, Medicaid, and other federal health-care programs is currently in effect. The June 2026 list records an exclusion with an effective date of October 18, 2012.
The list includes exclusions arising from a range of statutory bases, not all of which involve fraud or patient harm, and the basis for any individual listing must be confirmed at the source. Exclusion status can change: a party who is later reinstated is removed from the list at the next monthly update. This page reflects the June 2026 edition of the LEIE only.
