LEIE vs. SAM.gov: What's the Difference?

If you have ever Googled "OIG exclusion check," you have probably encountered two databases: the LEIE and SAM.gov. They sound like they do the same thing. They do not. Understanding the difference—and why you need to check both—is fundamental to running a compliant healthcare operation.

LEIE: The Healthcare Exclusion List

The List of Excluded Individuals and Entities (LEIE) is maintained by the Office of Inspector General (OIG) within the Department of Health and Human Services (HHS). It exists for one purpose: to identify individuals and entities that are excluded from participation in federal healthcare programs.

What it covers:

• Individuals and entities excluded under Sections 1128 and 1156 of the Social Security Act
• Exclusions resulting from healthcare fraud, patient abuse, felony convictions related to healthcare, and controlled substance violations
• Both mandatory exclusions (OIG must exclude) and permissive exclusions (OIG may exclude)

Who maintains it: OIG, a division of HHS

Update frequency: Monthly, typically around the 20th

Scope: Federal healthcare programs only (Medicare, Medicaid, CHIP, TRICARE, VA health)

The LEIE is the primary database for healthcare-specific exclusions. If someone committed healthcare fraud, abused a patient, or was convicted of a healthcare-related felony, they will almost certainly appear here.

SAM.gov: The Government-Wide Debarment List

The System for Award Management (SAM.gov) is maintained by the General Services Administration (GSA). It is a much broader database that covers all federal procurement and assistance programs—not just healthcare.

What it covers:

• Individuals and entities debarred, suspended, proposed for debarment, or declared ineligible across all federal agencies
• Exclusions resulting from fraud, criminal activity, or violation of federal contracting rules—in any industry, not just healthcare
• Entries from dozens of federal agencies, including HHS, DOD, DOJ, VA, and others

Who maintains it: GSA, with contributions from all federal agencies

Update frequency: Continuously (entries are added as agencies process them)

Scope: All federal programs, contracts, and grants

SAM.gov casts a wider net. An individual might be debarred from federal contracting due to fraud that had nothing to do with healthcare, but that debarment still makes them ineligible to participate in federal healthcare programs.

Where They Overlap

Here is where it gets confusing: OIG cross-reports some of its exclusions to SAM.gov. So a person excluded by OIG might appear in both the LEIE and SAM.gov. But the overlap is not complete.

An individual excluded by OIG will always appear in the LEIE. They will usually also appear in SAM.gov, but there can be timing delays between when OIG processes the exclusion and when it appears in SAM.gov.

Conversely, an individual debarred by the Department of Defense for procurement fraud will appear in SAM.gov but will not appear in the LEIE—unless they were also separately excluded by OIG.

Why You Need to Check Both

The critical point: an individual can be barred from participating in federal healthcare programs through either database. The Federal Acquisition Regulation (FAR) and the HHS regulations both require that providers not employ or contract with debarred or excluded individuals.

Checking only the LEIE means you will miss individuals who were debarred through non-healthcare channels but are still ineligible to participate in federal healthcare programs. Checking only SAM.gov means you might miss recently excluded individuals who have not yet been cross-reported.

Practical examples of people who might appear in one database but not the other:

• A medical supply company owner debarred for fraudulent billing to the Department of Defense: in SAM.gov, possibly not in LEIE
• A nurse excluded by OIG last week: in LEIE immediately, possibly not yet in SAM.gov
• A contractor suspended by the VA for safety violations: in SAM.gov, not in LEIE
• A physician excluded for patient abuse: in both LEIE and SAM.gov (after cross-reporting)

Practical Differences in Searching

The LEIE and SAM.gov have different search interfaces, different data formats, and different quirks.

The LEIE search requires first name and last name. It uses exact matching. Results include the exclusion type, the effective date, and the state. You can also download the entire LEIE as a CSV file for offline matching.

SAM.gov's exclusion search is part of a larger entity management system. The interface is more complex, and the data includes fields specific to federal contracting (CAGE codes, DUNS numbers, contract information). Exclusion records include the excluding agency, the exclusion type, and the termination date if applicable.

For healthcare providers, the challenge is that neither database's search tool is designed for the kind of bulk screening you need to do. Neither handles name variations gracefully. Neither provides an alert when a new exclusion matches someone in your staff roster. This is why automated screening with fuzzy matching has become the standard, and why OIG guidance recommends monthly screening as the baseline for reasonable diligence.

How ClientCare Checks Both

ClientCare screens your entire roster against both the OIG LEIE and SAM.gov in a single automated process. You do not need to search two different websites, reconcile two different result formats, or worry about timing gaps between databases.

When we find a match or potential match in either database, we surface it as a risk ticket on your dashboard with full context: which database flagged the match, the confidence score, the exclusion details, and the recommended next steps.

One upload. Both databases. Every month.
