Every name on the OIG exclusion list got there under one of two authorities, and the distinction matters more than it first appears. Mandatory exclusions are automatic, predictable, and tied to serious criminal convictions. Permissive exclusions are discretionary, cover a much wider range of conduct, and are where most providers are actually at risk.
Understanding which is which changes how you assess a candidate, how you evaluate a self-disclosure decision, and how you advise an employee facing a licensing board action.
Mandatory exclusions: no discretion, five-year minimum
Section 1128(a) of the Social Security Act requires OIG to exclude individuals and entities in four situations. There is no weighing of circumstances and no room for argument about whether exclusion is warranted. If the predicate conviction exists, exclusion follows.
The four mandatory grounds
- Conviction of a program-related crime. Any criminal offense related to the delivery of an item or service under Medicare or a state health care program, including Medicaid.
- Conviction relating to patient abuse or neglect. Any criminal offense relating to neglect or abuse of patients in connection with the delivery of a health care item or service.
- Felony conviction relating to health care fraud. Fraud, theft, embezzlement, breach of fiduciary responsibility, or other financial misconduct in connection with the delivery of a health care item or service — including in private-payer health care, not just federal programs.
- Felony conviction relating to controlled substances. Unlawful manufacture, distribution, prescription, or dispensing of a controlled substance.
The statutory minimum is five years. OIG can and does impose longer terms where aggravating factors are present — large financial losses, extended duration of the conduct, prior offenses, or harm to patients.
What counts as a “conviction”
Broader than most people assume. Under the statute, a conviction includes not only a judgment of guilt but also situations where a court has accepted a guilty or nolo contendere plea, and — critically — arrangements such as deferred adjudication or first-offender programs where a judgment was withheld.
This trips up a lot of people. An individual who accepted a deferred adjudication specifically to avoid a conviction on their record may still be convicted for exclusion purposes. Advising someone that “it wasn’t technically a conviction” is a mistake worth avoiding.
Permissive exclusions: discretion, and a much wider net
Section 1128(b) gives OIG the option to exclude on roughly sixteen different grounds. Because these are discretionary, OIG evaluates each case and may choose to exclude, to impose heightened scrutiny, to require integrity obligations, or to take no action at all.
The permissive grounds include:
- Misdemeanor convictions relating to health care fraud outside of Medicare or a state health program — including fraud against private insurers
- Convictions relating to fraud in any federal, state, or local government program, health care or otherwise
- Convictions relating to obstruction of an investigation or audit
- Misdemeanor convictions relating to controlled substances
- Suspension, revocation, or surrender of a health care license for reasons bearing on professional competence, professional performance, or financial integrity
- Exclusion or sanction by another federal or state health care program
- Claims for excessive charges or for services that were medically unnecessary or failed to meet professionally recognized standards of care
- Fraud, kickbacks, and other prohibited activities
- Failure to disclose required information, or to supply requested information on subcontractors and suppliers
- Defaulting on health education loan or scholarship obligations
- Controlling a sanctioned entity as an owner, officer, or managing employee
The one that catches the most people: 1128(b)(4)
Exclusion based on license loss is by far the most common permissive ground, and it is structurally different from the others in a way that matters operationally.
A 1128(b)(4) exclusion is indefinite. It has no fixed end date. It runs until the individual regains the license that was referenced in the exclusion notice — which means a clinician who surrenders a license during a board investigation, and never gets it back, can remain excluded indefinitely.
There is limited flexibility. An individual excluded under 1128(b)(4) may generally seek reinstatement if they obtain a different health care license in the same state, obtain any health care license in another state, or have been excluded for a minimum of three years. But none of those paths is automatic, and OIG evaluates each request on its merits.
The practical implication: nurses, physicians, pharmacists, and therapists who let a license lapse under disciplinary pressure — or who surrender one to end a board proceeding quietly — frequently do not understand they are creating a federal exclusion with no defined end date.
Owners and managing employees
Another permissive ground worth flagging: OIG may exclude individuals who own, control, or serve as officers or managing employees of a sanctioned entity. Exclusion is not confined to the person who committed the conduct. Leadership can be reached on the basis of their relationship to the organization.
Why the distinction matters in practice
Here is the compliance reality. For screening purposes, the distinction is irrelevant — an excluded person is excluded, and the payment prohibition and employer penalties are identical either way. You do not get a lighter penalty because the underlying exclusion was permissive.
But the distinction matters everywhere else:
Risk assessment. Mandatory exclusions arise from serious criminal convictions that typically surface in a standard background check. Permissive exclusions frequently arise from license actions and civil matters that a criminal background check will not reveal. This is a large part of why background screening and exclusion screening are not substitutes for one another.
Duration and monitoring. A five-year mandatory exclusion has a predictable end. A 1128(b)(4) exclusion may not end at all. If you are tracking a former employee’s status, or evaluating a candidate with a disclosed history, knowing the authority tells you what to expect.
Negotiation posture. Because permissive exclusion is discretionary, there is genuine room to engage with OIG. Individuals and entities can present evidence, and OIG has publicly described a spectrum of possible responses — from exclusion, to heightened scrutiny, to integrity obligations, to no further action, particularly where there has been cooperation or voluntary self-disclosure. That spectrum simply does not exist for mandatory exclusions.
Employee guidance. When a staff member discloses a pending licensing board matter or a criminal charge, the mandatory-versus-permissive analysis is what tells you whether exclusion is a certainty or a possibility, and how urgently the organization needs to plan around it.
What this means for your screening program
The breadth of the permissive grounds is the operational takeaway. Exclusion is not limited to people who defrauded Medicare. It reaches misdemeanors, private-payer fraud, license surrender, student loan default, and control relationships with sanctioned entities.
That breadth is exactly why point-in-time screening fails. A staff member with no criminal history at all can become excluded because a state licensing board acted, or because a loan went into default. Nothing about that shows up in a pre-employment background check, and nobody notifies the employer.
Monthly screening against the LEIE, state Medicaid exclusion lists, and SAM.gov is not a belt-and-suspenders measure. Given how many ways there are to end up excluded, it is the only mechanism that reliably catches a change in status before it becomes a liability.
