How to use this state index

Last verified: 2026-06-14. date_retrieved: 2026-06-14. This page narrows the imported HHS OIG LEIE file to Montana rows so reviewers can compare location, identifier, and exclusion fields before opening the official OIG verification sources.

OIG states that the downloadable LEIE database is replaced monthly with the current complete database of active exclusions. SourceCheckHealth surfaces the import timestamp, but it does not provide legal clearance, licensure verification, complete credentialing, or a final hiring decision.

Official verification

Confirm matches in OIG systems

State, ZIP, and name fields help reviewers triage possible matches, but OIG remains the source for current LEIE verification. Use the downloadable file for bulk review and the online search for specific individuals or entities.

Exclusion type codes are decoded only into the OIG authority category: mandatory under Social Security Act section 1128(a), or permissive under section 1128(b). Open OIG's authority table for the exact subsection and legal basis.

LEIE list context

What the LEIE (List of Excluded Individuals/Entities) is

The LEIE is the List of Excluded Individuals/Entities. OIG describes it as the list of “all currently excluded individuals and entities,” accessible via online search lookup or file download, used to verify that one or more individuals are not on OIG’s excluded list. This Montana page filters the imported LEIE download to Montana rows; it is one view of that national list, not a separate registry.

There are two official ways to use the LEIE for an exclusion list screening, and they differ in coverage:

  • File download (UPDATED.csv). The complete database of active exclusions, replaced monthly. Best for bulk screening of a provider or employee roster.
  • Online search. A name- or NPI-level lookup for confirming a single individual or entity and verifying current status before acting.

date_retrieved: 2026-06-14. SourceCheckHealth shows the imported Montana subset for review triage; OIG remains the authoritative source for current LEIE status.

FAQ

Practical notes

Is a state LEIE search the same as official OIG verification?

No. The state page is a browseable index of imported LEIE rows for review triage. Verify any exact or possible match in the official OIG online search or current downloadable LEIE before acting.

Why do some Medicare exclusion list rows have no NPI?

Not every LEIE row includes an NPI. Review name, business name, city, state, ZIP, exclusion type, and source date together, then confirm the record with OIG.

What does the exclusion type category mean on a state LEIE row?

SourceCheckHealth decodes the leading Social Security Act section in the OIG EXCLTYPE code only as mandatory under section 1128(a) or permissive under section 1128(b). Use OIG's authority table for the exact subsection and current legal context.

How often should OIG exclusion data be checked?

OIG guidance for state Medicaid agencies refers to monthly checks and checks during new enrollment. SourceCheckHealth shows import freshness so reviewers can decide whether a current official lookup is needed.

What is the LEIE (List of Excluded Individuals and Entities)?

The LEIE is OIG's List of Excluded Individuals/Entities: the list of all currently excluded individuals and entities, accessible via online search lookup or file download. This state page filters the imported LEIE download to one state's rows; it is a view of that national list, not a separate database.

Can I use this state index for OIG exclusion list screening?

Use it for review triage only. For exclusion list screening, OIG offers two official methods: the monthly UPDATED.csv download for bulk roster checks and the online search for confirming a single individual or entity. Verify any possible match in the official OIG source before acting.
