What Is an OIG Background Check and Who Needs One?

An OIG background check is a search of the List of Excluded Individuals and Entities (LEIE), a database maintained by the Office of Inspector General at the U.S. Department of Health and Human Services, to confirm that a person or organization has not been barred from participating in Medicare, Medicaid, or other federally funded healthcare programs. Any healthcare employer that bills a federal program needs to run this check on every employee, contractor, and vendor, and needs to keep running it, because employing someone on the list can trigger civil penalties now exceeding $25,000 per violation and can get the organization itself excluded.¹

What the Check Actually Screens

The LEIE lists every person and entity currently barred from federal healthcare program participation.² Once someone is on it, no federal healthcare program will pay for any item or service that person furnishes, orders, or prescribes. The payment ban applies across every reimbursement mechanism, and it applies even when the federal payment goes to a different, non-excluded provider who unknowingly relies on the excluded person’s work.³

People sometimes assume this overlaps with a criminal background check. It does not. Criminal checks scan arrest and conviction records. The LEIE contains people who were never convicted of anything: the OIG can exclude someone for losing a professional license, providing substandard care, submitting false claims, or participating in kickback arrangements.² Someone can clear a criminal check cleanly and still be excluded. Running one without the other leaves a real gap.

Who Needs to Be Screened

If your organization bills Medicare or Medicaid or provides services to program beneficiaries, screen the entire workforce. That includes physicians, nurses, therapists, and other clinicians, but it also includes billing staff, administrative employees, anyone who touches patient records or claims, and volunteers who interact with patients or program data.²

The obligation extends past your own payroll. Contractors, vendors, temporary staffing agency workers, and subcontractors who supply equipment, pharmaceuticals, or clinical services all need to be checked. Using a third-party staffing agency does not shift the liability. You still bear responsibility for verifying that the people they send you are not excluded, and the OIG has pursued providers who relied on outside agencies without confirming exclusion status independently.⁴

How to Run the Check

The OIG provides a free online search tool. Enter a name, and if a potential match appears, verify using a Social Security number for individuals or an Employer Identification Number for entities. The online tool accepts up to five names at a time.⁵

For larger workforces, the OIG also publishes a downloadable version of the full LEIE. Compliance teams can run bulk checks against their entire employee, contractor, and vendor roster. Supplemental files listing new exclusions and reinstatements are posted monthly, so you can merge updates into your existing data instead of re-downloading the whole database each cycle.⁵

How Often to Screen

The OIG updates the LEIE around the middle of each month, and each update reflects the exclusion and reinstatement actions from the prior month.⁵ Monthly screening of the entire workforce lines up with that cycle and is the defensible practice. Someone who was clean last month can appear on the list this month, and the penalty exposure starts when they land on the LEIE, not when you notice.

Screen every new hire, contractor, and vendor before they start. Pre-hire screening alone is not enough. A person can be excluded at any point during employment, so an organization that checks only at onboarding is carrying undetected risk for however long stretches between reviews.

Why the Cadence Matters: Penalties

The financial exposure for keeping an excluded person on the payroll is severe. After inflation adjustments, the civil monetary penalty maximum has risen to $25,595 per violation.¹ That maximum can be applied two different ways:

Up to $25,595 for each day an excluded person remains employed or under contract.
Up to $25,595 for each item or service the excluded person furnishes, orders, or prescribes that gets billed to a federal program, plus an assessment of up to three times the amount claimed.⁶

Those figures compound quickly. An excluded employee on staff for six months generates more than $4.6 million in potential per-day penalties before any claims-based penalties are counted. The organization itself can also be excluded from federal healthcare programs, which for most providers is an existential outcome, and knowingly employing an excluded person can bring criminal prosecution.

The LEIE Is Not the Only List

Screening only the LEIE leaves gaps. The federal government also maintains the System for Award Management (SAM), administered by the General Services Administration, which contains debarment actions taken by various federal agencies. The LEIE contains only the OIG’s own exclusion actions, so a person debarred by another federal agency can appear in SAM but not on the LEIE.⁵

Most states also maintain their own Medicaid exclusion lists, and someone can be excluded at the state level without appearing on the federal LEIE. A thorough screening program checks all three: the LEIE, SAM, and the applicable state exclusion list. Organizations operating under a Corporate Integrity Agreement with the OIG face additional obligations. Under a typical agreement, employing or contracting with an excluded person is a reportable event that must be disclosed to the OIG within 30 days.⁷

Reinstatement Is Not Automatic

Do not assume that a candidate whose exclusion period has expired is cleared to work. When the exclusion period ends, the individual has to submit a written application to the OIG and receive formal written notice that reinstatement has been granted. Until that letter arrives, the person remains excluded, and anyone employing them remains exposed to penalties.⁸

The practical implication for hiring is simple. Do not rely on an applicant or an employee telling you their exclusion has ended. Confirm that the name is no longer on the LEIE, which happens only after the OIG formally grants reinstatement and removes the record.⁹

If You Find an Excluded Person on Staff

Discovering an excluded individual on your payroll is a compliance emergency, and the response affects the outcome. First step: remove the person from any role connected to federal healthcare programs immediately.

Then consider the OIG’s Provider Self-Disclosure Protocol, which allows organizations to voluntarily report self-discovered potential fraud, including the employment of excluded individuals.¹⁰ Self-disclosure can avoid the cost and disruption of a government-directed investigation. For excluded-employee cases, the OIG will reduce the damages calculation by the organization’s federal payor mix, which can meaningfully lower total exposure. The submission has to include the specific calculations and documentation the protocol requires; incomplete submissions can be rejected.
