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 ingests OIG LEIE monthly and cross-resolves exclusion records against NPPES and PECOS for context. Verisys adds value through continuous monitoring automation and multi-source aggregation, not through access to the federal LEIE record itself.
- How often does the OIG update the LEIE?
- OIG publishes a refreshed LEIE file monthly. Fonteum re-ingests it each month. If an individual is excluded mid-month, they may not appear in the monthly file until the next publication cycle — so for continuous compliance programs requiring same-day alerts, a commercial monitoring service like Verisys that tracks in-cycle updates adds value.
- What is the legal requirement for OIG exclusion screening?
- CMS and OIG guidance require providers and suppliers to check the LEIE before hiring or contracting with individuals and entities, and to re-screen monthly for employed staff. The underlying data source for that requirement is the OIG LEIE itself — which is freely available. Commercial platforms like Verisys automate the workflow; they do not change the underlying legal source.
