OIG LEIE (Federal Exclusion List) vs Verisys: Side-by-Side Comparison
OIG LEIE is the federal List of Excluded Individuals and Entities — the authoritative record of providers barred from Medicare and Medicaid billing, published free monthly by the U.S. Department of Health and Human Services. Verisys is a commercial credentialing and sanction-screening platform that includes LEIE alongside dozens of other sanction and licensing sources.

Which platform fits your team
When to use OIG LEIE (Federal Exclusion List)
Use OIG LEIE directly when the requirement is specifically federal Medicare/Medicaid exclusion checks — either for a one-time lookup or for building a sanction-screening pipeline on primary-source federal data. It is free, monthly-refreshed, and fully auditable.
When to use Verisys
Use Verisys when the compliance program requires continuous monitoring across OIG LEIE plus state Medicaid exclusions, SAM.gov, and other licensing and sanction sources simultaneously — with automated alerts and audit reports instead of DIY file processing.
Common questions
- Is OIG LEIE the same as what Verisys screens against?
- OIG LEIE is one of the sources Verisys screens against, but Verisys aggregates additional lists including state Medicaid exclusion lists, SAM.gov (federal contractor exclusions), and various licensing boards. The OIG LEIE component traces to the same federal record; the additional databases are proprietary aggregations.
- Do I need to pay for Verisys to check OIG LEIE?
- No. OIG LEIE is available free at oig.hhs.gov as a monthly bulk CSV download and through a free online search tool. Fonteum's loaded release was dated May 8, 2026 when checked July 12; confirm current status at OIG. Verisys adds workflow automation and multi-source aggregation, not access to the federal file itself.
- How often does the OIG update the LEIE?
- OIG publishes a refreshed LEIE file monthly. Fonteum's loaded release was dated May 8, 2026 when checked July 12, so its table may trail the official file. Confirm consequential status at OIG.
- What is the legal requirement for OIG exclusion screening?
- Providers can face liability when federal programs are billed for items or services furnished by an excluded party. OIG advises checking the LEIE before employing or contracting and periodically afterward; because OIG updates the file monthly, its guidance says monthly screening best minimizes potential liability. The LEIE itself is freely available. Commercial platforms automate the workflow; they do not change the underlying legal source.
