OIG/SAM Background Check: Step-by-Step Guide to LEIE and SAM.gov Exclusion Screening

An effective OIG/SAM background check safeguards your organization from Federal healthcare exclusions, billing risk, and ineligible contracting. This step-by-step guide shows you how to screen the OIG LEIE database and SAM.gov Exclusions, document results, and embed exclusion screening protocols into daily operations.

Understanding LEIE

The LEIE (List of Excluded Individuals/Entities) is maintained by HHS OIG and identifies people and organizations barred from participating in Federal healthcare programs. If someone appears on LEIE, they are generally not eligible to bill or be paid—directly or indirectly—by Medicare or Medicaid, which are classic Medicare/Medicaid exclusions.

LEIE focuses on program-related misconduct in healthcare. SAM.gov, by contrast, aggregates government-wide exclusions and debarments that impact eligibility for federal awards and contracts. Together, they provide a complete view of contracting eligibility verification for healthcare and non-healthcare engagements funded by the federal government.

Key distinctions

• LEIE: Healthcare-specific; affects reimbursement and participation in Federal healthcare programs.
• SAM.gov Exclusions: Government-wide; affects awards, grants, procurement, and subawards per SAM.gov compliance requirements.
• Best practice: Check both to cover reimbursement and contracting exposure.

Accessing SAM.gov Exclusion Lists

SAM.gov hosts a public Exclusions search. You can query individuals or entities by name, Unique Entity ID (UEI), or legacy identifiers (e.g., DUNS/CAGE on older records). Filters allow you to focus on Active Exclusions and narrow by exclusion type or agency.

Practical steps

• Open the Exclusions search and select Active to focus on current restrictions.
• Search by legal name; then try common variations, initials, and former or DBA/trade names.
• For companies, search by UEI and any known legacy identifiers to catch historical records.
• Review each record’s details (name, status, cause/agency, date ranges) to assess federal contracting eligibility.

Document the SAM.gov screen, record identifiers, and note the date/time of the query to preserve your audit trail for regulatory background checks.

Collecting Identifying Information

Accurate inputs reduce false positives and speed reviews. Before screening, compile a standardized data set for each person or entity you onboard or renew.

Provider/individual data

• Full legal name (first/middle/last), aliases, prior names, and common nicknames.
• Date of birth; professional license numbers; NPI; states of licensure.
• Current and prior addresses; employer/affiliations; known email or phone (for verification).

Entity/vendor data

• Legal name; DBA/trade names; prior legal names.
• UEI; EIN; legacy DUNS/CAGE if available.
• Principal addresses; key executives/owners for name-based checks when warranted.

Use a consistent naming convention and capture attestations that the subject is not excluded. Store only the minimum identifiers necessary and follow your privacy and retention policies.

Querying Exclusion Databases

Run both LEIE and SAM.gov searches for every subject. Use multiple variations to avoid missed matches.

Step-by-step workflow

• LEIE search: Start with exact legal name, then try aliases and common misspellings. Use available identifiers (e.g., NPI, state, specialty) to refine matches.
• SAM.gov Exclusions: Search by legal name and UEI; expand to prior names and DBAs. Filter to Active Exclusions first, then check Inactive to understand history.
• Entity nuance: For organizations, screen both the entity and, when risk-appropriate, principals whose names might appear independently.
• Documentation: Save a dated record of each query and result (including “no results found”) for your exclusion screening protocols.
• High-volume populations: Consider batch or automated screening capabilities and a reconciliation log to track new, cleared, and unresolved hits.

Reviewing Screening Results

When you find a potential match, confirm identity before taking action. False positives are common with common names and partial identifiers.

How to validate a match

• Cross-check unique identifiers: NPI, UEI/EIN, license numbers, date of birth, addresses.
• Compare contextual details: specialty, state, known affiliations, or prior names.
• Assess status: Active vs. Inactive/Terminated matters for both reimbursement and contracting decisions.

If you confirm an LEIE match, address Medicare/Medicaid exclusions immediately in your operations. For SAM.gov, evaluate whether an Active Exclusion blocks awards, subawards, or payments and coordinate with procurement, grants, or legal teams. Record your determination, rationale, and all supporting evidence.

Ensuring Regulatory Compliance

Build a written compliance framework that specifies who screens, when, how, and how results are handled. The framework should align with SAM.gov compliance requirements and healthcare payment rules.

Core elements of your program

• Scope: Employees, medical staff, contractors, vendors, and subcontractors that impact federal billing or awards.
• Timing: At onboarding/award, at renewal, and on a recurring cadence appropriate to risk.
• Data sources: OIG LEIE database, SAM.gov Exclusions, and any state or program-specific lists your payors require.
• Response plan: Escalation, temporary hold procedures, and corrective actions for confirmed exclusions.
• Documentation: Central log of queries, results, adjudications, and communications for audits.
• Training and attestations: Educate HR, credentialing, supply chain, and grants teams; require periodic non-exclusion attestations.

Embed contracting eligibility verification in your procurement and credentialing workflows so that no engagement proceeds without completed screening and documented clearance.

Scheduling Regular Background Checks

Adopt a cadence that balances risk, volume, and operational practicality. Many organizations screen LEIE monthly and SAM.gov at onboarding, prior to renewals or payments, and on a monthly or quarterly cycle based on risk.

Recommended cadence

• Baseline: Screen both databases before hire, privileging, contracting, or award.
• Ongoing: Monthly LEIE screening is a widely adopted practice; SAM.gov screening monthly or quarterly, with mandatory checks prior to awards and renewals.
• Event-driven: Re-screen on name changes, new licenses, M&A, ownership changes, or adverse media.
• Quality assurance: Periodically sample results, verify documentation quality, and audit turnaround times.

Operationalizing the schedule

• Centralize the roster of subjects and automate reminders and batch queries where possible.
• Maintain a single source of truth for outcomes, including “no match” evidence and adjudication notes.
• Report metrics (volume screened, hits, time-to-resolution) to leadership to sustain resourcing.

Conclusion

Consistently pairing LEIE and SAM.gov checks, validating potential matches, and documenting every step protects reimbursements, awards, and reputation. With clear exclusion screening protocols, defined ownership, and a reliable cadence, your OIG/SAM background check program will meet regulatory background checks expectations and keep federal risk in check.

FAQs.

What is the OIG LEIE list?

The OIG LEIE list is the federal roster of individuals and entities excluded from participating in Federal healthcare programs. An appearance on LEIE typically means you cannot bill or be paid—directly or indirectly—by programs like Medicare or Medicaid until reinstated.

How often should OIG/SAM background checks be conducted?

Screen both databases at onboarding or prior to award, then on a recurring cadence. Many organizations run monthly LEIE checks and screen SAM.gov monthly or quarterly, with mandatory checks before awards, renewals, or payments. Adjust frequency based on risk, contract terms, and payor expectations.

What are the consequences of contracting with an excluded party?

You risk repayment of federal funds, civil monetary penalties, contract termination, grant ineligibility, reputational harm, and potential False Claims Act exposure. Prompt detection and documented response steps are critical to mitigate damage.

How do I interpret exclusion screening results?

First, confirm identity using unique identifiers and context. Next, determine status (Active vs. Inactive) and the scope of restrictions. Finally, document your decision, coordinate with compliance or legal, and implement holds or clearance steps consistent with your policy.
