Exclusion screening

How to screen for OIG, SAM, and state Medicaid exclusions

OIG recommends checking the LEIE before employing or contracting and periodically afterward; because it updates the list monthly, OIG says monthly screening best minimizes potential liability. Applicable state, contract, and program rules can differ. This guide covers the LEIE, SAM.gov, relevant state Medicaid lists, and dated records. Fonteum's on-demand screen checks up to 25 NPI inputs against the supported federal and loaded state registries and shows counts plus a matched-source breakdown on screen.

Screen your roster against the currently loaded lists — right now

Paste your provider NPIs and see matches from OIG LEIE, SAM.gov, and the currently loaded state Medicaid lists. Up to 25 unique ten-digit NPI inputs are screened. The result stays on screen: no download, email delivery, or monitoring. No PHI; the roster is not stored.

Public NPIs only. No PHI. No free artifact, email, or monitoring enrollment. Do not submit a confidential roster or affiliation list. This public GET URL can appear in browser history, logs, analytics, shared links, and referrers.
Re-check any match

We keep dated copies of the exclusion lists currently loaded for screening. Paste a record id to pull its receipt and check it against the government's own file — no account.

Re-check it yourself

Look up a snapshot id to see the source, date, digest, and chain fields that record actually returns. Digest comparison checks archive bytes; signature status is shown separately. No account needed.

The lists

Which exclusion lists must a healthcare provider screen?

A complete healthcare exclusion screen covers two federal lists and every applicable state Medicaid list. Fonteum currently combines the two federal lists with the loaded state lists (GA, IA, MD, MS, MT, NC, ND, NH, NY, OH, PA, TN, WA) into a single “excluded-anywhere” signal, and adds a separate “compromised-anywhere” layer for NPI-linked federal integrity records short of exclusion. It does not claim coverage of the other states.

The process

How to screen a provider roster for exclusions

  1. Assemble the roster you must screenList every provider, contractor, vendor, and ordering/referring party you bill federal programs for. CMS expects you to check anyone who furnishes items or services payable by a federal health program — not just the parties on your own payroll.
  2. Screen the two federal listsCheck each name and NPI against the OIG LEIE (HHS healthcare-program exclusions) and SAM.gov (government-wide debarment). These are the baseline federal lists every program expects you to check.
  3. Screen every applicable state Medicaid exclusion listAn individual excluded by one state's Medicaid program can relocate and practice elsewhere. Screening only the federal lists — or only your own state — leaves that gap open. Fonteum mirrors the currently loaded state Medicaid exclusion lists (GA, IA, MD, MS, MT, NC, ND, NH, NY, OH, PA, TN, WA) in one pass. Fonteum does not claim coverage of the other states. Any loaded source whose serving coverage is stale or cannot be matched to an attested artifact returns indeterminate.
  4. Resolve matches by NPI, then confirm at the sourceFonteum's on-demand product accepts ten-digit NPIs, not name-only rows. Confirm every consequential match against the primary list before any adverse action; a false match can flag the wrong provider, and a missed match can hide an excluded one.
  5. Document the screen and set a recurring cadenceKeep a dated record showing which list you checked, on what date, and the matched record. OIG updates the LEIE monthly and says monthly screening best minimizes potential overpayment and civil-monetary-penalty exposure; applicable state and program rules can differ.
Per-state guides

How to check a specific state's Medicaid exclusions

Each guide names the state's Medicaid integrity authority and links the primary list. The product screen currently loads state lists for GA, IA, MD, MS, MT, NC, ND, NH, NY, OH, PA, TN, WA; a guide does not imply that its state is already loaded.

FAQ

Common questions

How do I screen for OIG exclusions for free?
Search the OIG LEIE directly, or use Fonteum's free OIG exclusion search by name or NPI. Fonteum's on-demand roster screen accepts up to 25 unique ten-digit NPI inputs and shows counts plus a matched-source breakdown on screen only. It checks OIG LEIE, SAM.gov, and the currently loaded state Medicaid exclusion lists (GA, IA, MD, MS, MT, NC, ND, NH, NY, OH, PA, TN, WA); it does not create a free report, send email, or enroll monitoring.
How often does OIG recommend exclusion screening?
OIG says providers are not generally required by statute or regulation to check the LEIE, but recommends checking before employing or contracting and periodically afterward. Because OIG updates the LEIE monthly, it says monthly screening best minimizes potential overpayment and civil-monetary-penalty exposure. Applicable state, contract, and program rules can impose their own cadence.
What is the difference between the OIG LEIE and SAM.gov?
The OIG LEIE (List of Excluded Individuals and Entities) is the HHS Office of Inspector General's list of parties excluded from federal healthcare programs under sections 1128 and 1156 of the Social Security Act. SAM.gov holds government-wide debarments across all federal agencies and procurement. They overlap but are distinct: a healthcare compliance screen needs both, plus the relevant state Medicaid exclusion lists.
Do I need to screen state Medicaid exclusion lists too?
Yes. Most state Medicaid programs publish their own exclusion or termination lists, and a provider excluded by one state may not appear on the federal LEIE. CMS guidance and many state contracts require screening the applicable state lists. Fonteum mirrors the currently loaded state Medicaid exclusion lists (GA, IA, MD, MS, MT, NC, ND, NH, NY, OH, PA, TN, WA) alongside the OIG LEIE and SAM.gov. Fonteum does not cover the other states.
What does it cost to bill for an excluded provider?
Under Section 1128A of the Social Security Act, civil monetary penalties, additional assessments, and repayment can apply when federal programs are billed for items or services furnished by an excluded party (see OIG guidance on the effect of exclusion). The applicable amounts are adjusted over time; consult the current statute, regulations, and OIG guidance rather than relying on a static dollar figure.
What does Fonteum's free roster screen include?
The current roster screen accepts up to 25 unique ten-digit NPI inputs, not arbitrary name-only rows. It checks supported NPI-keyed records against the , SAM.gov, and the state Medicaid exclusion lists currently loaded (GA, IA, MD, MS, MT, NC, ND, NH, NY, OH, PA, TN, WA), plus OIG Corporate Integrity Agreements and CMS civil-money-penalty records, when an NPI-linked record is available. Other states are not covered. Results show counts and a matched-source breakdown on screen only; no free artifact, email, or monitoring is created. A negative may be indeterminate when source coverage is stale or incomplete. Public data only — no PHI.

Integrated, with-data, and fresh-observation counts are separate. No platform-wide source-completeness count is published. Completeness is source-specific and must be evaluated against the named source's expected scope. State coverage is a separate jurisdiction measure.

Source authority is record-specific

Use the issuer named on the record.

Fonteum spans federal, state, and global public publishers. A source page or returned record identifies its issuer and dataset where that metadata is available. A platform registry count does not assign every page to one authority or establish loaded, fresh, or complete coverage.

Source and date

Research pages expose the named public file and observation date where those fields are available. Source-file SHA-256 coverage is separate; facts do not currently link deterministically to signatures.

Available derivation

Studies with a retained release and committed derivation link the SQL or method used. Other studies state the evidence and reproduction limits they actually have.

Daily observations

Dated table row-count observations can detect local drift. They do not imply that an upstream publisher released or Fonteum ingested new data that day.
