The Credible Allegation of Fraud Standard in Medicaid Enforcement

A single, uncorroborated fraud hotline tip can be enough to trigger a mandatory suspension of a Medicaid provider's payments. Once a state Medicaid agency determines that a credible allegation of fraud exists and an investigation is pending, suspending payment to that provider is not discretionary; it is required, absent a documented good cause exception. For a pharmacy, physician practice, or home health agency, the effect is immediate: reimbursement stops while the allegation is investigated, often before any finding of wrongdoing. Understanding what qualifies as credible, what exceptions exist, and what process is available once a suspension notice arrives is essential to responding effectively.

What Counts as Credible

The standard is set by federal regulation at 42 CFR 455.2. A credible allegation of fraud is defined as an allegation that has been verified by the state, from any source, including fraud hotline complaints, claims data mining, and patterns identified through provider audits, civil False Claims Act cases, and law enforcement investigations. An allegation is credible when it has indicia of reliability and the state Medicaid agency has reviewed the facts and evidence carefully and acted judiciously. The threshold is deliberately low: the regulation does not require the state to substantiate the fraud first. A single referral, without more, can satisfy the standard in many circumstances, because states retain broad discretion over what counts as reliable.

The Mandatory Suspension Trigger

Once a state Medicaid agency finds a credible allegation of fraud and an investigation is pending, 42 CFR 455.23 requires the state to suspend all Medicaid payments to the provider, in whole or in part, unless good cause exists not to. The suspension is not a penalty for proven wrongdoing; it is a protective measure tied to a pending investigation. The state must also refer the matter in writing to the Medicaid Fraud Control Unit or other law enforcement agency by the next business day after the suspension takes effect. The provider must receive written notice, generally within five days, unless law enforcement asks to delay it, a delay that can extend to 30 days and, on renewal, up to 90 days total. The notice must describe the general nature of the suspension without disclosing investigation details, confirm it is temporary, and identify when it will end.

Allegations are considered to be credible when they have indicia of reliability and the state Medicaid agency has reviewed all allegations, facts, and evidence carefully and acts judiciously on a case-by-case basis.

Good Cause Exceptions

Suspension is the default rule, but 42 CFR 455.23(e) allows a state to decline to suspend, or to suspend only in part, when good cause exists: a written law enforcement request, a finding that another remedy better protects Medicaid funds, a state determination based on the provider's own written evidence, or a threat to beneficiary access where the provider is one of few sources of care in the area. A state may also decline to suspend when law enforcement will not certify its investigation is active, or when suspension would not serve the program's best interests. None of these exceptions apply automatically; the provider bears the burden of putting the relevant facts before the state.

Due Process Limits

The due process available to a provider facing suspension is narrower than many expect. The regulation entitles the provider to written notice and an opportunity to submit written evidence for the state's consideration and, where state law provides for it, some form of administrative review. It does not require a full evidentiary hearing or cross-examination before the suspension takes effect. In practice, the provider's written submission, and how quickly it is prepared, is often the only chance to affect the suspension before it takes hold, drawing on what the provider already knows about its own billing history and any parallel inquiry, including a prior state OMIG audit, already underway.

Why Early Legal Counsel Is Critical

It is critical that healthcare providers promptly retain experienced healthcare defense counsel upon receiving a subpoena, audit notice, investigative request, or other government inquiry. Early legal intervention can protect the provider's rights, ensure appropriate responses to government requests, avoid inadvertent admissions, preserve relevant defenses, and allow counsel to communicate with investigators on the provider's behalf. Delaying legal representation can significantly affect the outcome of a matter and expose the provider to unnecessary risk.
