How Often Should You Check the OIG Exclusion List for Employees?

OIG Exclusion List Overview

The Office of Inspector General maintains the List of Excluded Individuals and Entities (LEIE), commonly called the OIG Exclusion List. It identifies people and organizations barred from participating in Federal healthcare programs due to certain convictions, licensure issues, or program violations. If an excluded individual or entity furnishes, orders, or is paid for items or services, those claims are not payable.

Screening the LEIE is central to Federal Healthcare Program Compliance. Medicare and Medicaid Exclusions protect program integrity by preventing payment linked to excluded parties. Because exclusions can apply to direct care, administrative functions, and supply chains that touch federally reimbursed services, you need a reliable, organization‑wide process to detect and prevent prohibited relationships.

The LEIE is the authoritative OIG database. Many organizations also check state Medicaid exclusion lists and other sanction sources as part of broader due diligence, but the LEIE remains the core reference for OIG exclusions.

Recommended Screening Frequency

Conduct Pre-Employment Screening against the LEIE before a hire’s start date, and then screen your entire applicable population at least monthly. Monthly checks align with the LEIE’s regular publication cadence and minimize the window in which a new exclusion could expose your organization to risk.

Beyond monthly workforce screening, apply checks at key trigger points: when roles change (e.g., moving into ordering, billing, or referral positions), upon rehire or return from extended leave, during vendor onboarding, and when critical identifiers (name, NPI, license) change. For higher-risk groups, many organizations layer continuous monitoring supported by Exclusion Screening Tools.

If you bill or receive payment from state Medicaid programs, also screen applicable state Medicaid exclusion lists on a monthly basis in addition to the LEIE. This dual cadence helps ensure Medicare and Medicaid Exclusions are consistently addressed.

• Before start date: Pre-Employment Screening of employees, contractors, and medical staff.
• Monthly: Organization-wide LEIE checks (plus relevant state lists).
• Onboarding and annually thereafter: Vendors and other third parties tied to claims.
• Ad hoc triggers: Role changes, name/identifier updates, or credentialing events.

Legal Consequences of Non-Compliance

Claims involving excluded individuals or entities are not payable. If payment occurs, you may face overpayment obligations and be required to refund amounts tied to the prohibited services. Payers and auditors often scrutinize related claims, which can trigger retrospective reviews and repayment demands.

Exclusion Penalties can include civil monetary penalties, assessments, and potential False Claims Act exposure for knowingly submitting or causing the submission of tainted claims. Repeated or egregious failures may lead to corporate integrity agreements, termination of payer contracts, and reputational harm.

Operationally, discovering an excluded party after the fact disrupts staffing, credentialing, and revenue cycles. The downstream impact—claim holds, resubmissions, corrective action plans—often costs far more than maintaining a robust screening program.

Best Practices for Screening

Establish a written policy that mandates LEIE screening and defines roles, frequency, sources, documentation standards, and escalation paths. Integrate screening into onboarding, credentialing, recredentialing, and vendor management workflows so checks happen automatically, not ad hoc.

Strengthen match accuracy by collecting reliable identifiers (full legal name, aliases, date of birth, NPI, license numbers) at onboarding and keeping them current. Use Exclusion Screening Tools with strong identity resolution to reduce false positives and accelerate match verification.

• Centralize rosters for employees, medical staff, contractors, and vendors to avoid gaps.
• Screen against the LEIE and applicable state Medicaid exclusion lists on a monthly schedule.
• Define a documented process to investigate potential matches and confirm or clear them promptly.
• Maintain an auditable trail: source files, match logs, decisions, dates, and responsible personnel.
• Train HR, credentialing, compliance, and supply chain teams on procedures and escalation.
• Perform periodic internal audits to validate completeness and timeliness.

Scope of Screening Requirements

Include anyone who directly or indirectly touches Federal healthcare program claims or services. That scope typically extends beyond employees to affiliated individuals and organizations whose work can generate, support, or influence reimbursement.

• Employees, licensed independent practitioners, medical staff, residents/fellows, students, volunteers, and temps.
• Contractors and locums; staffing agencies and their placed personnel.
• Vendors and service providers involved in clinical services, billing, coding, revenue cycle, IT systems supporting claims, or item/supply chains reimbursed by federal programs.
• First-tier, downstream, and related entities for delegated functions; owners or managing individuals where applicable.

Apply the same cadence to entity names and to principals where required. For Pre-Employment Screening, ensure offers are contingent on successful exclusion checks, and repeat screening monthly to capture new exclusions.

Challenges in Screening Processes

Common hurdles include name variations and aliases, limited identifiers on public records, and high volumes that strain manual workflows. Multi-entity systems face fragmented rosters, while vendor networks complicate oversight. Verifying reinstatements and documenting every decision can also be resource-intensive.

Mitigate these challenges with standardized data capture, routine data hygiene, and Exclusion Screening Tools that provide probabilistic matching, automated rechecks, and audit-ready logs. Establish clear SLAs for investigating potential matches, and routinely test your process through internal audits.

Regulatory Compliance Expectations

Regulators expect an effective, risk-based compliance program that actively prevents, detects, and corrects exclusion risks. That typically includes written policies, ongoing monitoring and auditing, board and leadership oversight, staff training, timely response to issues, and comprehensive documentation showing that screening occurs at hire and at least monthly thereafter.

Maintain evidence of each screening cycle, investigative notes for potential matches, and documented outcomes. Coordinate with credentialing and supply chain to ensure LEIE and state Medicaid exclusion checks cover all people and entities tied to federally reimbursed items and services. This disciplined approach supports sustained Federal Healthcare Program Compliance.

Bottom line: check the OIG Exclusion List before onboarding and at least monthly across your workforce and relevant vendors, use reliable tools to automate and document the process, and keep thorough records to demonstrate compliance over time.

FAQs

How frequently should employee exclusion screenings be conducted?

Screen at hire (before the start date) and at least monthly thereafter. Add checks at key triggers—role changes, rehire, or identifier updates—and consider continuous monitoring with Exclusion Screening Tools for higher-risk roles.

Who must be included in OIG exclusion screenings?

Include employees, licensed practitioners, medical staff, residents/fellows, students, volunteers, temps, contractors, and vendors tied to items or services reimbursed by federal programs. Also include delegated entities and, where applicable, owners or managing individuals connected to those entities.

What are the penalties for hiring excluded individuals?

You risk nonpayment of related claims, repayment obligations, civil monetary penalties, and potential False Claims Act exposure. Additional consequences can include contract terminations, reputational damage, and heightened oversight or corrective action requirements.

How can organizations automate exclusion list checks?

Adopt Exclusion Screening Tools that integrate with HRIS, credentialing, and vendor systems. Look for features like automated monthly or continuous monitoring, strong identity matching, coverage of the LEIE and state Medicaid lists, alerting, workflow for match resolution, and audit-ready reporting.
