Overview

The Office of Inspector General of the U.S. Department of Health and Human Services is the largest inspector general’s office in the federal government, responsible for combating fraud, waste, and abuse in Medicare, Medicaid, and more than 100 other HHS programs. Established in 1976 and headquartered in Washington, D.C., the OIG operates with a staff of approximately 1,600 as of 2025 and an annual budget that supports criminal investigations, civil enforcement, audits, and compliance guidance across the healthcare system.

For behavioral health treatment facility operators, the OIG represents the enforcement arm of the federal government’s effort to protect the integrity of healthcare programs. The agency investigates healthcare fraud, maintains the List of Excluded Individuals/Entities, enforces the Anti-Kickback Statute, and publishes compliance guidance that shapes how your facility structures its business operations. Unlike agencies that focus on clinical standards or funding, the OIG focuses on whether healthcare entities are billing honestly, compensating fairly, and operating within the boundaries of federal law.

The OIG’s relevance to behavioral health has grown substantially in recent years as the opioid crisis drove significant increases in treatment funding and, with it, fraud. The OIG has identified substance use treatment as an enforcement priority, with investigations targeting patient brokering, kickback arrangements, unnecessary services, and billing fraud. For legitimate operators, understanding OIG expectations and building robust compliance programs is both a legal obligation and a competitive advantage.

Why OIG Matters for Behavioral Health Providers

The OIG’s enforcement authority carries consequences that can end a treatment facility’s ability to operate. Exclusion from federal healthcare programs — the most severe administrative sanction the OIG imposes — means your facility cannot participate in Medicare, Medicaid, or any other federal healthcare program. For most treatment centers, this is effectively a business-ending action. Criminal prosecution of fraud cases can result in imprisonment for responsible individuals. Civil monetary penalties for violations such as employing excluded individuals or violating the Anti-Kickback Statute can reach hundreds of thousands of dollars per violation.

The OIG exclusion list screening requirement is one of the most straightforward but commonly mismanaged compliance obligations. Federal law prohibits paying individuals or entities that have been excluded from federal healthcare programs. If your facility employs an excluded individual — even unknowingly — you can face civil monetary penalties of up to approximately $100,000 per item or service that excluded person provided, though penalty amounts are subject to change. The OIG expects facilities to screen all employees, contractors, and vendors against the LEIE before engagement and on a regular ongoing basis. Monthly screening is the standard recommended by the OIG and required by many state Medicaid programs.

The Anti-Kickback Statute is the other major area of OIG enforcement affecting behavioral health facilities. This statute broadly prohibits exchanging anything of value to induce or reward referrals for services covered by federal programs. For treatment facilities, this affects how you structure referral relationships, marketing arrangements, transportation services, and business partnerships. The behavioral health field has seen significant enforcement activity around patient brokering — paying third parties for referrals — and arrangements where facilities provide free housing, transportation, or other benefits to attract clients covered by insurance or public programs.

The OIG’s compliance program guidance provides a framework for building the internal controls that reduce fraud risk and demonstrate good faith. Having a functioning compliance program does not immunize your facility from enforcement action, but it can significantly mitigate penalties if issues are discovered. More importantly, a well-designed compliance program helps you identify and correct problems before they escalate to the level that attracts OIG attention.

Key Programs and Services

List of Excluded Individuals/Entities (LEIE). The LEIE is a publicly searchable database of individuals and organizations excluded from participation in federal healthcare programs. Exclusions result from criminal convictions, civil findings, licensing board actions, and other grounds specified in the Social Security Act. Your facility must check the LEIE as part of your hiring process and conduct ongoing screening for all current staff and contractors.

Anti-Kickback Statute Enforcement. The OIG enforces the Anti-Kickback Statute, which prohibits the exchange of remuneration to induce or reward referrals for services covered by federal healthcare programs. The OIG publishes safe harbor regulations that describe specific business arrangements that do not violate the statute. Understanding safe harbors helps operators structure compliant business relationships.

Civil Monetary Penalties. The OIG can impose civil monetary penalties for a range of violations including billing for services not rendered, employing excluded individuals, violating the Anti-Kickback Statute, and making false claims. Penalties vary by violation type but can reach approximately $100,000 or more per violation, plus treble damages, though penalty amounts are subject to adjustment. The OIG publishes its enforcement actions to promote transparency and deterrence.

Compliance Program Guidance. The OIG has published compliance program guidance for various healthcare sectors, including general guidance applicable to behavioral health facilities. The guidance outlines seven core elements of an effective compliance program: written policies and procedures, compliance officer designation, training, auditing and monitoring, reporting mechanisms, enforcement of standards, and corrective action.

Advisory Opinions. The OIG issues advisory opinions in response to specific requests from parties seeking guidance on whether particular business arrangements potentially violate the Anti-Kickback Statute or other OIG-enforced rules. While advisory opinions apply only to the requesting party, they provide useful guidance on how the OIG evaluates common business arrangements.

Work Plan and Enforcement Priorities. The OIG publishes an annual Work Plan identifying planned audits, evaluations, and investigations. Reviewing the Work Plan helps operators understand which areas the OIG is focusing on and where enforcement resources are being directed. Behavioral health has appeared as an enforcement priority in recent Work Plans.

How OIG Affects Your Facility

Employee and Vendor Screening. Implement a systematic process for screening all employees, contractors, vendors, and business partners against the LEIE before engagement and monthly thereafter. Document all screening activities, including the date of each check, the individual or entity screened, and the results. Many compliance software platforms automate this process. State Medicaid programs may require screening against additional state-level exclusion databases.

Referral Practices. Structure all referral relationships to comply with the Anti-Kickback Statute. Do not pay for referrals. Do not offer free housing, transportation, or other benefits as inducements for referrals. If you enter into marketing agreements, ensure they are structured within applicable safe harbors. If you are uncertain about a business arrangement, seek legal counsel before proceeding. The behavioral health field has seen significant enforcement activity in this area.

Billing Integrity. Bill only for services actually rendered, documented, and medically necessary. Ensure that the service billed matches the service provided and that documentation supports the level of service claimed. Train billing staff on proper coding practices and implement internal auditing to detect errors before they become patterns that attract enforcement attention.

Compliance Program Implementation. Build and maintain a compliance program based on OIG guidance. Designate a compliance officer, develop written policies, train all staff, establish a reporting mechanism for compliance concerns, conduct internal audits, and take corrective action when problems are identified. A compliance program is not just a defensive measure — it is a management tool that helps you run a cleaner, more efficient operation.

Responding to Investigations. If your facility receives an inquiry from the OIG or a law enforcement agency, engage legal counsel immediately. Do not destroy documents, alter records, or instruct staff to avoid cooperation. Timely, organized responses to investigations, supported by documented compliance activities, position your facility more favorably than defensive or obstructive approaches.
