The OIG's own LEIE search is free and takes up to 5 names at a time, and 1Lookup answers one provider from your own software for $0.015.

Checking whether a person or a business is on the List of Excluded Individuals/Entities, the list the HHS Office of Inspector General keeps of those excluded from federal health care programs. The OIG says the list is 'accessible via online search lookup or via file download'. The search form takes a last name and a first name for an individual or the name of an entity, and it can confirm a match with a Social Security Number for an individual or an Employer Identification Number for an entity.

It is free. The pages read list no plan, quota or charge for the online search or for the downloadable file, and neither page shows a sign-in form. The OIG updates the list every month: its exclusions FAQ says 'All exclusion information is updated by the 10th of every month'. Checked October 2026.

3 credits per completed check, billed for every completed check, a clear one included. On the Starter plan ($99 a month for 20,000 credits) a check is about $0.015, which covers 6,666 checks a month and is $14.85 per 1,000. At the Enterprise end of the rate card it is about $0.006. The OIG search is the cheaper bill: it is free, against $99 for a Starter month.

No. The OIG's quick-tips page asks 'Are there plans to put a public API on the LEIE database?' and answers 'No, there are no plans for a public API.' Its FAQ points to the other route for many names: 'consider downloading the entire list via the LEIE Downloadable Database and using a spreadsheet or database program to perform searches.' 1Lookup does that work for you: you send an NPI, a name or a business name in one API request, or a CSV with a provider column, and get one answer per provider, with the list date in each.

The online search returns the matching rows, and the OIG asks the searcher to 'Maintain documentation of the initial name search performed and any additional searches conducted'. 1Lookup returns a verdict in a plain word for each provider: excluded when the NPI is on the list, needs review when a name matches, reinstated, or clear. Each answer names the exclusion type in words, gives the listing's NPI, birth year, specialty, city and state to compare with your own record, and states the date of the list it checked. A bulk CSV starts every row with a Result column that always holds a word, so a provider who is on no list never reads as a blank row.

On price, and on confirming a match. It is the source and it is free. It is the only one of the two that can confirm a match with a Social Security Number or an Employer Identification Number, and the OIG says 'It is not sufficient to simply find a matching first and last name on the LEIE'. 1Lookup takes neither number and returns the birth year the list carries, never a date of birth. The OIG also posts a monthly supplement of exclusions and of reinstatements, kept for the previous 12 months, and offers email updates when the list changes. 1Lookup has none of these.

Both read the OIG's list. The OIG replaces its file every month, by the 10th. 1Lookup keeps its copy up to date through the month, puts the date of the list in every answer so you can see which version was checked, and is not billed when the list cannot be read. A repeat of the same check by the same user within 1 day comes from the cache at no charge, so a new exclusion can reach a screen the next day.

Not with a Social Security Number or an Employer Identification Number. A name match is called needs review and never an approval, and an NPI that is on the list is called excluded. The answer carries the listing's NPI, birth year, specialty, city, state, exclusion type and date, so you can compare it with the person's record before acting. 1Lookup checks the OIG list only; state Medicaid exclusion lists are separate.

If you check a few names by hand and want it free, or need to confirm a match with a Social Security Number or an Employer Identification Number, the OIG's own search is the right tool, and nothing beats it on price. If you want the OIG list checked from your own software, a spreadsheet of providers or a hiring flow, by NPI or by name, with a verdict and the list date in each answer, 1Lookup's OIG Exclusion Check bills 3 credits per completed check on the same balance that pays for phone, email and IP checks.

Yes, for checking a handful of names by hand: it is free, official and able to verify an identity. The OIG says it has no plans for a public API, and the search is built for people typing names, with strict rules (it accepts only apostrophes, hyphens, ampersands and commas in its search fields, and asks you to check name variations and each part of a hyphenated name). For a list of providers, an application or a recurring screen, compare the per-check price of 1Lookup.
