Differences Between the OIG’s LEIE and GSA’s SAM Exclusion Lists

Posted by Joe Stefansky on January 11, 2021 in Exclusions, LEIE, SAM,


It is the government’s responsibility to protect its health and human services programs from fraud and abuse, as well as to safeguard the welfare of those who benefit from those programs.  The OIG (“Office of Inspector General”) maintains a comprehensive exclusion database called the List of Excluded Individuals/Entities (“LEIE”), for this express purpose. The General Services Administration (“GSA”) similarly maintains several exclusion lists, managed through the System for Award Management (“SAM”).

 A significant distinction between the LEIE and the SAM databases is scope – the LEIE database contains only exclusion actions taken by HHS OIG, while the SAM database includes debarment actions taken by a number of federal agencies in addition to HHS OIG. Therefore, these databases are related, but there are differences.


The OIG LEIE database is a complete listing of all individuals and entities currently excluded by the OIG pursuant to sections 1128 and 1156 of the Social Security Act (“the Act”). The effect of an exclusion under either section is that no payment will be made by the subject programs for any items or services furnished, ordered or prescribed by an excluded individual or entity. The LEIE is updated each month. Upon reinstatement, a previously excluded individual or entity may petition to be removed from the LEIE.

The scope of the exclusions under Section 1128 of the Act is from all federal health care programs including Medicare, Medicaid, and other Federal health care programs that provide health benefits funded directly or indirectly by the United States.  The scope of an exclusion under section 1156 of the Act is from Medicare and all state health care programs as defined by 1128 of the Act.   

The LEIE is publicly available on the OIG website in two formats:

> The Online Searchable Database enables users to search by individual or entity name to determine exclusion status. If a match is made on an individual, the database can verify with the individual’s Social Security Number that the match is unique. Employer Identification Numbers (EINs) are available for verification of excluded entities.

> The Downloadable Database of the entire LEIE is available as well for download to a personal computer. This version of the LEIE is comprehensive, including the name of the excluded individual or entity, provider type and specialty, National Provider Identifier (issued by CMS), date of birth, address and exclusion type.

Individuals and entities end up on the LEIE exclusion list due to either a mandatory or permissive exclusion by the OIG. 

A mandatory exclusion by the OIG occurs when an individual or entity is convicted of a felony offense. This may include conviction for fraud related to Medicare or Medicaid or other state or federal health care programs, patient neglect or abuse or a felony offense related to controlled substances. The OIG has no discretion in the case of a mandatory exclusion. On the other hand, in the case of a misdemeanor by an individual or entity, the OIG has discretion issue a permissive exclusion based on the facts of the matter.

To ensure that both federal and state criminal actions taken against health care providers are captured, state Medicaid Fraud Control Units (“MFCU”) are obligated to notify the OIG of any terminations or exclusions, which are then included on the LEIE.  The OIG can levy monetary penalties against those who have incurred them, and even civil fines, to a significant degree.

For more information about the LEIE, the OIG has posted a bulletin on its website which offers comprehensive guidance on the effect of exclusion from federal health care programs.


The GSA maintains centralized database for government contracting known as SAM. The database is a procurement repository and includes all contractors approved to do business with the federal government as well as those who are excluded from participation in federal procurement. SAM incorporates data from multiple federal databases – the Central Contractor Registry (CCR), the Federal Agency Registration (FedReg), Online Representations and Certifications Application (ORCA), and the Excluded Parties List System (EPLS) – as well as the OIG’s LEIE.

A major difference between the GSA and OIG is that the while the GSA maintains SAM as database of federal procurement systems, the GSA is not an agency with authority to levy fines and penalties, unlike HHS OIG.

Other differences include the categories employed by SAM, classifying excluded entities according to the following four categories:

> Ineligible with proceedings incomplete

> Ineligible with proceedings done

> Prohibition/Restriction

> Voluntary Exclusion

Another difference between the LEIE and SAM is the basis for exclusion. The OIG’s exclusions, as described above, are relatively straightforward.  However, a contractor may be excluded from participation in a federal contract under SAM for a variety of reasons. For example, foreign nationals barred from entering the US are prohibited from bidding on federal contracts, and individuals who have violated national security protocol are excluded. A conviction for tax fraud or default on a student loan debt can also result in exclusion. Essentially, when a federal agency has concerns about unethical behavior, the agency may seek to exclude an individual or entity from participation in future federal procurement opportunities.

As a practical matter, the SAM.gov database is less user-friendly than the LEIE database. For example, GSA exclusions require the Dun & Bradstreet number of an institutional entity on the exclusion list, and the database does not include provider license or NPI data. Searching for individuals via SAM is more complicated than via the LEIE. Additionally, LEIE includes more details about persons or entities excluded by the OIG than the details found in SAM.

To improve user experience and to modernize SAM, a major transition will be occurring in the near future.  The GSA issued a notice announcing that in April 2021, the functionalities of SAM.gov will be integrated into the modernized beta.SAM.gov environment. The new design will likely change the presentation of current data sets and information on beta.SAM.gov, but it will not change core data or core functions of the system. Once the integration occurs, the system will hopefully provide a more modern search portal for users. Whether the modernized SAM proves to be more user-friendly remains an open question.


In addition to LEIE and SAM,  42 states and jurisdictions maintain their own Medicaid exclusion lists. These lists include violations of state law that do not necessarily violate federal law – and may not be reported to the federal databases.  This is despite the fact that the federal Affordable Care Act (“ACA”) now mandates that if a provider or entity is excluded under any state Medicaid database, that provider should be excluded from participating in all states.

Checking all of the above noted databases creates significant administrative burdens for entities required to do so. While there is overlap between these exclusion lists, best practice is to search all of them in order to obtain the most comprehensive information on excluded, sanctioned and debarred individuals and entities.

Therefore, health care businesses should conduct an LEIE check as well as screen against SAM and state exclusion lists in order to assure that all excluded individuals and entities are not involved in provision of care or services on behalf of the business.
