CMS Medicaid Suspension Defense and Medicare Suspension Defense

Knowledgeable Attorneys for CMS Medicaid Suspension Defense and Medicare Suspension Defense

A Medicaid or Medicare payment suspension can happen before a single formal charge is ever filed. Unlike exclusion or a civil settlement, which typically follow a lengthy investigation, a payment suspension can take effect almost immediately once the government determines it has a “credible allegation of fraud” against a provider. For a healthcare business, this can mean an abrupt halt to the revenue stream it depends on, often with only limited notice and even more limited opportunity to respond before the suspension begins.

At The Criminal Defense Firm, we represent healthcare providers, agencies, and organizations facing payment suspension actions from the Centers for Medicare and Medicaid Services (CMS), state Medicaid agencies, and their program integrity contractors. Our attorneys, including former federal prosecutors, provide Medicaid fraud defense and understand both the legal standards governing suspension and the practical urgency providers face when their cash flow is suddenly cut off.

What Is a Medicaid or Medicare Payment Suspension?

A payment suspension is a temporary withholding of some or all Medicaid or Medicare payments to a provider while an investigation proceeds. It is not a final determination of guilt and does not require a criminal conviction, or even formal charges, to take effect. Instead, suspensions are typically triggered once the government concludes it has a “credible allegation of fraud” against the provider, a standard that is intentionally lower than the burden of proof required at trial.

Suspensions can be imposed at the state level under Medicaid program integrity rules, at the federal level by CMS under Medicare regulations, or in some cases, both simultaneously if a provider participates in both programs. Because Medicaid and Medicare suspensions operate under separate but similarly structured legal frameworks, providers facing action from one program often need to prepare for parallel scrutiny from the other.

The Legal Standard: Credible Allegation of Fraud

Under federal Medicaid regulations at 42 CFR 455.23, and the parallel Medicare law at 42 CFR 405.371, payments must generally be suspended once a state or federal agency determines it has a credible allegation of fraud against a provider, unless the agency finds good cause not to suspend. A “credible allegation” can come from a wide range of sources, including fraud hotline complaints, claims data analysis identifying billing anomalies, provider self-disclosures, or referrals from law enforcement or other state agencies.

Importantly, the credible allegation standard does not require the government to have already substantiated the fraud. It requires only that the allegation has “indicia of reliability” and that the agency has reviewed the allegation and supporting facts. This low threshold is precisely why a suspension can occur early, and often unexpectedly, in the life of an investigation.

The “Good Cause” Exceptions

• Law enforcement has specifically requested that a suspension not be imposed in order to avoid compromising an ongoing investigation
• Other administrative remedies are already adequately protecting program funds
• The suspension would jeopardize beneficiary access to care, and no reasonable alternative exists

Because these exceptions are narrow and largely discretionary, providers rarely succeed in avoiding suspension by arguing good cause alone. Where a stronger opportunity exists, it is usually in demonstrating that the underlying allegation itself lacks the reliability the regulations require, or that the scope of the suspension should be narrowed rather than eliminated.

Notice Requirements and Provider Rights

Providers are generally entitled to written notice of a payment suspension, though the specific timing and content of that notice differ between Medicaid and Medicare and can vary by state. In many cases, the notice will be delivered at or near the same time the suspension takes effect, rather than in advance, since providing advance notice could allow a provider to alter records or take other steps that would undermine the investigation.

The notice typically must identify the general allegations at issue, though agencies are often permitted to withhold specific investigative details that could compromise a pending law enforcement matter. Providers do have a right to submit a rebuttal statement responding to the suspension, and in most jurisdictions, the agency must consider that rebuttal, though it is not required to lift the suspension based solely on the provider’s response. These deadlines are frequently short and unforgiving, so you must understand the procedural rules.

How Long Can a Suspension Last?

Medicaid and Medicare suspensions are meant to be temporary, but “temporary” in this context can still mean many months or longer. Federal regulations generally tie the duration of a suspension to the status of the underlying investigation, and suspensions are often extended repeatedly as an investigation continues. In practice, this means a provider may operate without expected Medicaid or Medicare revenue for an extended period, even if the investigation never results in formal charges.

This makes early, aggressive engagement with the investigating agency essential. The longer a suspension remains in place without meaningful pushback, the more entrenched it tends to become, and the more difficult it can be to demonstrate to the agency that continued suspension is no longer warranted.

The Financial and Operational Impact of Suspension

For most healthcare providers, Medicaid and Medicare payments represent a substantial share of total revenue. A suspension, even a partial one, can create an immediate cash flow crisis, threatening payroll, lease obligations, and the ability to continue serving existing patients. 

Providers may also face secondary consequences, including default triggers under loan covenants tied to program participation, difficulty maintaining commercial insurance contracts, and reputational harm with referral sources who become aware of the suspension.

Because these consequences compound quickly, the response to a suspension notice cannot wait. Providers need an immediate assessment of their legal options alongside practical guidance on managing the operational fallout while the matter is contested.

Our Approach to Defending Against Suspension

When a provider is notified of a payment suspension, our first priority is understanding exactly what allegation triggered the action and what evidence the agency is relying on. From there, we work to challenge the reliability of the underlying allegation where possible, pursue available good cause arguments to narrow or lift the suspension, and prepare a thorough rebuttal statement that directly addresses the agency’s stated concerns.

At the same time, we engage directly with investigators and agency counsel to understand the trajectory of the broader investigation, since resolving or narrowing that underlying matter is often the most effective way to bring a suspension to an end. Where a suspension has already caused significant financial harm, we also advise providers on the interplay between the suspension and other pending obligations, including lender covenants, vendor contracts, and any parallel state licensing proceedings.

Suspension Compared to Exclusion

It is important for providers to understand that suspension and exclusion are legally distinct actions with different consequences. A suspension is a temporary withholding of payment during an investigation and does not itself bar a provider from participating in Medicaid or Medicare going forward. 

Exclusion, by contrast, is a determination that a provider may not participate in federal healthcare programs at all, typically following a conviction or a substantiated finding of fraud, and generally lasts for a defined minimum period or permanently in the most serious cases.

A suspension can, however, be a precursor to exclusion if the underlying investigation results in formal charges or an adverse finding. This is one of the reasons an aggressive, early response to a suspension matters even beyond the immediate financial pressure it creates.

Frequently Asked Questions

Q: What does “credible allegation of fraud” mean?

It is a legal standard requiring that an allegation have some indicia of reliability and that the agency has reviewed the underlying facts. It does not require proof of fraud and is intentionally a lower threshold than what would be required to convict or find civil liability.

Q: Can a suspension happen before I know I’m being investigated?

Yes. In many cases, the suspension notice is a provider’s first indication that an investigation is underway, since agencies are often permitted to withhold advance notice to protect the integrity of the investigation.

Q: How long does a Medicaid or Medicare suspension typically last? 

There is no fixed maximum, and suspensions are generally tied to the status of the underlying investigation. Suspensions can last for many months or longer, particularly if the investigating agency does not receive pushback or a compelling rebuttal from the provider.

Q: Can I keep treating Medicaid or Medicare patients while my payments are suspended?

In most cases, a payment suspension does not prohibit a provider from continuing to see patients, but it does mean the provider will not be paid for those services during the suspension period, which creates significant financial strain for most practices.

Q: What is a rebuttal statement, and does filing one guarantee the suspension will be lifted?

A rebuttal statement is a provider’s formal written response challenging the basis for the suspension. Agencies are generally required to consider it, but they are not required to lift the suspension based on the rebuttal alone. A well-prepared rebuttal is still one of the most important tools available to a provider.

Q: Is a payment suspension the same as being excluded from Medicaid or Medicare?

No. A suspension is a temporary withholding of payment during an investigation. Exclusion is a separate, more permanent bar from program participation that typically follows a conviction or a substantiated fraud finding. A suspension can, however, lead to exclusion if the investigation results in an adverse outcome.
