What Is the LEIE List? HHS OIG’s Exclusions Explained and How to Check It

Purpose of the LEIE List

The List of Excluded Individuals/Entities (LEIE) is the U.S. Department of Health and Human Services Office of Inspector General’s public registry of people and organizations barred from participating in federal healthcare programs. Its core purpose is to protect program dollars and patients by identifying OIG sanctioned entities and individuals who have engaged in conduct that threatens Federal Healthcare Program Integrity.

When someone appears on the LEIE, Medicare, Medicaid, and other federal healthcare programs generally cannot pay for any items or services furnished, ordered, or prescribed by that person or entity. This payment prohibition helps prevent repeat misconduct, deters fraud, and promotes Fraud and Abuse Prevention across the healthcare system.

The LEIE also promotes transparency. By making Exclusion Enforcement visible and searchable, HHS OIG Exclusion Authority signals clear consequences for violations and gives providers, plans, vendors, and contractors a reliable tool to vet relationships before claims are submitted.

Criteria for Exclusion

Exclusions arise under federal law, primarily the Social Security Act’s mandatory and permissive authorities. The HHS OIG Exclusion Authority distinguishes between conduct that requires exclusion and conduct for which exclusion is discretionary, with the length and scope tailored to the severity and context.

Mandatory grounds (baseline five-year exclusion)

• Program-related convictions such as healthcare fraud or theft involving Medicare/Medicaid funds.
• Patient abuse or neglect in connection with the delivery of healthcare services.
• Felony convictions relating to healthcare fraud or financial misconduct tied to a federal healthcare program.
• Felony convictions relating to the unlawful manufacture, distribution, prescription, or dispensing of controlled substances.

Permissive grounds (case-by-case discretion)

• Misdemeanor convictions or civil judgments involving fraud, kickbacks, or false statements connected to healthcare.
• License revocation or suspension, or surrender of a license while under investigation.
• Quality-of-care failures or substandard performance that risks patient safety.
• Obstruction of an investigation, or failure to provide required access to records.
• Ownership or control relationships with an excluded or OIG sanctioned entity.

Length and scope

Mandatory exclusions typically start at five years and may be extended using aggravating factors such as high-dollar loss, leadership role in the misconduct, or sustained patterns of wrongdoing. Permissive exclusions vary in length based on mitigating and aggravating factors. After the exclusion period ends, reinstatement is not automatic; you must follow Exclusion Reinstatement Procedures to regain eligibility.

Types of Excluded Parties

Anyone who threatens the integrity of a federal healthcare program can face exclusion. The LEIE includes both individuals and organizations, reflecting the many roles that touch patient care and claims.

Individuals

• Clinicians such as physicians, nurses, pharmacists, therapists, dentists, and behavioral health providers.
• Non-licensed staff involved in billing, coding, utilization review, case management, or claims submission.
• Owners, officers, board members, and managing employees who direct operations or finances.
• Ordering, prescribing, and referring professionals whose actions can trigger Medicare/Medicaid Exclusion effects downstream.

Entities

• Hospitals, clinics, skilled nursing facilities, behavioral health centers, and home health agencies.
• Clinical laboratories, DMEPOS suppliers, pharmacies, infusion centers, and transportation providers.
• Managed care organizations, IPAs, MSOs, and other intermediaries that receive federal program funds.

The Exclusion Enforcement framework applies regardless of whether services are billed directly. If an excluded person furnishes, directs, or prescribes services, federal payment is generally prohibited even when another party submits the claim.

Checking the LEIE Database

Routine screening is one of the most effective Fraud and Abuse Prevention controls you can implement. You should check the LEIE at onboarding, during credentialing and re-credentialing, before engaging contractors, and on an ongoing basis aligned to the list’s update cadence.

Practical screening workflow

1. Identify your screening population: employees, medical staff, contractors, temps, volunteers, owners, board members, and key vendors tied to federal claims.
2. Collect identifiers to refine matches: full legal name, prior names/aliases, date of birth, National Provider Identifier (NPI) when applicable, and known addresses.
3. Use the LEIE’s online lookup for single-name checks and the downloadable data set for batch or enterprise screening.
4. Search every known name and alias. For common names, use additional identifiers to distinguish true matches.
5. Document results, including date of search, data source (online vs. download), search terms used, and match outcome.
6. For potential matches, perform a secondary verification by comparing identifiers (e.g., NPI, DOB). Do not allow the individual or entity to furnish or influence federally reimbursed services until resolved.
7. Retain records to demonstrate diligence and support audits, investigations, or payer credentialing requests.

Best practices

• Screen monthly to align with the LEIE’s update frequency and reduce payment risk.
• Extend screening obligations to subcontractors through contract language and attestations.
• Integrate screening into HRIS, credentialing, and vendor management systems to prevent missed checks.
• Train managers and recruiters to recognize red flags and escalate quickly.

Consequences of Exclusion

Exclusion is more than removal from a roster; it attaches powerful payment and participation consequences designed to uphold Federal Healthcare Program Integrity.

• Payment prohibition: Federal healthcare programs generally will not pay for items or services furnished, ordered, or prescribed by an excluded person or entity, even if the claim is submitted by a non-excluded provider.
• Overpayment liability: Claims tied to excluded participation become overpayments that you must identify, report, and return promptly.
• Civil Monetary Penalties (CMPs): Employing or contracting with an excluded party for federally reimbursed services can trigger significant CMPs and assessments.
• False Claims Act exposure: Knowing submission of claims involving excluded participation may invite FCA liability and corporate integrity obligations.
• Operational disruption: Credentialing denials, payor terminations, reputational harm, and corrective action plans can follow.
• Extended exclusion: Continued noncompliance or new misconduct can lengthen or broaden Exclusion Enforcement.

Update Frequency and Maintenance

HHS OIG updates the LEIE monthly. New exclusions and reinstatements appear with each cycle, so your screening cadence should, at a minimum, match this frequency. Many organizations layer real-time or weekly interim checks for high-risk roles.

Maintenance tips

• Schedule automated monthly screenings and reconcile any deltas from prior runs.
• Archive reports and match-resolution notes to create a defensible audit trail.
• Refresh identifiers (e.g., new NPIs, name changes) to keep your screening accurate.
• Coordinate across HR, compliance, credentialing, and supply chain so no group becomes a blind spot.

Exclusion Reinstatement Procedures

Reinstatement is not automatic at the end of an exclusion term. An individual or entity must apply to HHS OIG, demonstrate eligibility, and receive written confirmation before participating in federal programs again. Until reinstatement is granted, the Medicare/Medicaid Exclusion remains in force.

Compliance and Reporting Requirements

An effective compliance program makes LEIE screening routine, documented, and actionable. Embed controls in your hiring, credentialing, contracting, and claims workflows to prevent excluded participation before it happens.

Build a practical program

1. Policy and scope: Define who is screened, when, and how often; include employees, privileged providers, owners, contractors, and critical vendors.
2. Roles and accountability: Assign screening, verification, and escalation duties to specific teams; require leadership oversight.
3. Training and attestations: Educate staff on exclusion risks and obtain periodic certifications from workforce and vendors.
4. Technology integration: Automate monthly checks and maintain centralized documentation of results and resolutions.
5. Match resolution: Use a documented process to verify potential matches quickly and restrict assignments pending clearance.
6. Corrective action: If you confirm exclusion, immediately remove the individual or entity from federally reimbursed activities, quantify related claims, and implement remedial steps.
7. Reporting and refunds: Follow your legal and payer obligations to report and return identified overpayments within required timeframes.

Continuous improvement

• Trend analysis: Track near-misses and confirmed issues to strengthen controls where gaps appear.
• Vendor governance: Bake LEIE screening and notification duties into contracts; require prompt disclosure of investigations or sanctions.
• Fraud and Abuse Prevention: Coordinate exclusion controls with auditing, monitoring, hotline reporting, and disciplinary standards.

Conclusion

The LEIE is a cornerstone of Federal Healthcare Program Integrity. By understanding HHS OIG Exclusion Authority, screening monthly, and responding decisively to potential matches, you lower fraud risk, protect reimbursement, and sustain compliance. Treat exclusion checks as a routine control—not a one-time task—and you will prevent costly errors before they reach a claim.

FAQs

What is the LEIE list used for?

The LEIE identifies individuals and entities that are excluded from federal healthcare programs so you can avoid employing, contracting with, or billing for services tied to them. It enables Exclusion Enforcement and helps providers maintain compliance and Fraud and Abuse Prevention.

How often is the LEIE list updated?

HHS OIG updates the LEIE monthly. To stay aligned, you should screen at onboarding and at least monthly thereafter, using both online lookup for spot checks and the downloadable file for batch screening.

Who can be excluded from the LEIE list?

Both individuals (e.g., clinicians, billing staff, owners, managers) and organizations (e.g., clinics, labs, pharmacies, DME suppliers) can be excluded based on mandatory or permissive grounds under HHS OIG Exclusion Authority.

What are the impacts of being on the LEIE list?

Exclusion generally bars federal payment for items or services furnished, ordered, or prescribed by the excluded party, creates overpayment and Civil Monetary Penalty risk for employers and contractors, and can trigger credentialing denials, reputational harm, and extended sanctions until Exclusion Reinstatement Procedures are completed.
