ProviderTrust prints no price and sells monitoring by demo, and 1Lookup checks a provider against the OIG list for $0.015 with a self-serve key.

Screening and monitoring healthcare workforces and provider networks. Its monitoring page says it 'keeps watch continuously, so your team catches new exclusions, sanctions, and disciplinary actions as they occur'. The sources it names include the HHS-OIG LEIE, SAM.gov, state Medicaid exclusion and sanction lists, the CMS Preclusion List, the NPPES NPI Registry, the Medicare Opt-Out list, OFAC's lists and the Social Security Death Master File.

By quote. The pages read print no plan, price or free tier, and the product pages end in 'Book a Demo'. The API documentation says user accounts 'are provisioned by your ProviderTrust implementation team', and that sandbox access can be granted for development testing. 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. ProviderTrust prints no price, so no figure can be set beside these.

Yes. Its documentation lists subjects, events, subscriptions and webhooks, an instant search by NPI, one-time verifications and credential checks, with a production and a sandbox environment. The instant search takes one NPI per request ('Exactly one NPI is allowed per request'), the docs ask clients to limit calls to 10 requests per second, and the API key is created inside the ProviderTrust app by an account that its implementation team provisions, then exchanged for a token valid for 12 hours. 1Lookup's key comes from a self-serve account and one call checks an NPI, a name, a business name, or an NPI and a name together.

On scope, monitoring and assurance. It watches people and organizations continuously, covers state Medicaid lists, SAM.gov, the CMS Preclusion List, OFAC and more beside the OIG list, and its certifications page lists HITRUST CSF certification (r2), SOC 2 Type II compliance and NCQA credentialing certification. 1Lookup checks the OIG list only, does not monitor a roster and does not alert you when a new exclusion appears.

Both read the OIG's list, which the OIG replaces every month, by the 10th. ProviderTrust describes continuous monitoring across its sources. 1Lookup puts the date of the OIG list in every answer, refreshes its copy through the month 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.

For a single question, whether a provider is on the OIG list right now, yes. For continuous monitoring, state Medicaid lists, credentialing or an audited platform, no. A 1Lookup check answers when you ask, and a CSV of your providers can be re-checked on whatever schedule you run it. 1Lookup checks the OIG list only; state Medicaid exclusion lists are separate.

If you need continuous monitoring across a workforce or provider network, more lists than the OIG's, or HITRUST and SOC 2 Type II reports, ProviderTrust is built for that and sells it by quote. If you want to check an NPI or a name against the OIG list from your own software today, on a printed price with a key you create yourself, 1Lookup's OIG Exclusion Check bills 3 credits per completed check on a balance that also pays for phone, email and IP checks.

For a health system, payer or staffing firm that needs ongoing monitoring and wants a vendor to run it, yes: it is a full platform with wide list coverage and certifications. Its API documentation says the product and API are 'still subject to significant and potentially breaking changes', and no price is printed, so you learn the cost on a demo. If the job is a screen at the point of hiring or onboarding, compare the per-check price of 1Lookup.
