Insurance Fraud Defense: Federal Insurance Fraud Charges Explained

By Elizabeth Franklin-Best, Esq., and Christopher Zoukis, JD, MBA

Insurance fraud is often thought of as a state crime, but when a claim, a policy, or a payment crosses state lines, it becomes a federal case — and federal prosecutors treat it seriously. If you are a policyholder, claimant, agent, broker, adjuster, or insurance-company insider under federal scrutiny, the time to retain an insurance fraud lawyer is before your next statement to anyone, because these cases turn on intent and on the precise representations made in a claim or a filing. At Elizabeth Franklin-Best, P.C., we defend clients against federal insurance fraud allegations nationwide.

Federal insurance fraud is prosecuted in two main ways: as mail and wire fraud, when a scheme to defraud an insurer is carried out through the mail or interstate wires, and under 18 U.S.C. § 1033, the federal statute aimed at fraud by and against insurers engaged in interstate commerce. The conduct can range from a single inflated claim to a large, organized scheme — and the exposure scales accordingly.

Our firm brings a federal-court defense practice grounded in detailed statutory analysis and controlling case law. Elizabeth Franklin-Best, the firm’s principal attorney, has represented clients in more than 330 federal proceedings and over 100 federal appeals before the United States Supreme Court and all twelve federal circuits; she holds 2026 recognition on two fronts: Best Lawyers in America for Appellate Practice and a Chambers USA ranking for Litigation: White-Collar Crime & Government Investigations. Our starting point in an insurance fraud matter is the gap between a dispute and a deception — we map the charged elements against the claim file and test whether the government can prove fraudulent intent rather than a genuine disagreement over coverage or value. Schedule a paid, one-hour initial consultation to begin that analysis.

Key Takeaways

• Insurance fraud becomes a federal case when a scheme uses the mail or interstate wires, or when it falls under 18 U.S.C. § 1033.
• Claim-side fraud — staged losses, arson for profit, inflated or fabricated claims — is most often charged as mail and wire fraud.
• Section 1033 targets fraud by people in the business of insurance: false statements to regulators and the misappropriation of insurer funds.
• The government must prove fraudulent intent — a knowing scheme to deceive — not merely a disputed or overstated claim.
• Mail and wire fraud carry up to 20 years per count; § 1033 offenses carry up to 10 years, or 15 where an insurer’s solvency is jeopardized.
• Agents, brokers, adjusters, and public adjusters can be charged alongside policyholders and claimants.
• A genuine, good-faith dispute about the value or coverage of a claim is not insurance fraud.
• Because these cases turn on intent and on the documents, early defense work is critical.

What Is Federal Insurance Fraud?

Insurance fraud, in broad terms, is the use of deception to obtain a benefit from an insurer that is not owed — or, on the industry side, the abuse of an insurer’s funds or the deception of insurance regulators. Most insurance fraud is prosecuted under state law. It becomes a federal matter — one form of federal fraud — when the scheme is carried out through the mail or interstate wires, or when it falls within a federal insurance statute.

Federal insurance fraud has two broad faces. The first is claim-side fraud — conduct by policyholders, claimants, or those who assist them. It includes staging or fabricating a loss, committing arson to collect on a property policy, inflating the value of a genuine loss, billing for treatment or repairs that never occurred, and submitting false information on an insurance application. The second is industry-side fraud — conduct by people in the business of insurance, such as agents who pocket premiums, executives who misstate an insurer’s finances to regulators, or insiders who misappropriate company funds.

What both faces share is the requirement of intent. Insurance is, by nature, a field of disputes — over coverage, over valuation, over causation. A policyholder who submits a claim the insurer denies, an adjuster who values a loss differently than the carrier, or an applicant who makes an honest mistake has not committed federal insurance fraud. The crime requires a knowing intent to deceive, and that line between a dispute and a fraud is the foundation of the defense.

Why Insurance Fraud Is Usually State — and When It Goes Federal

Insurance occupies an unusual corner of American law: under the McCarran-Ferguson Act, 15 U.S.C. §§ 1011–1015, regulation of the business of insurance is reserved primarily to the states. That structure explains the enforcement landscape. Every state maintains an insurance fraud bureau or equivalent unit, state statutes criminalize false claims and applications, and the bulk of insurance fraud prosecutions are brought by district attorneys and state attorneys general. Congress added the focused federal offenses in §§ 1033 and 1034 only in 1994, after a wave of insurer insolvencies exposed gaps in state-level oversight. One caution: McCarran-Ferguson is not a defense to a federal indictment — in United States v. Cavin, 39 F.3d 1299 (5th Cir. 1994), the Fifth Circuit held that federal fraud prosecutions are compatible with state insurance regulation and that the Act erects no bar to them, a view courts have consistently followed.

Federal prosecutors step in along predictable lines. Multi-state and organized schemes — staged-accident rings, networks of complicit clinics or body shops, serial arson-for-profit operations — draw federal attention because they outrun any one state’s jurisdiction. So do large-dollar losses, schemes involving federally connected coverage such as flood or crop insurance, catastrophe-related fraud after federally declared disasters, and industry-side misconduct that threatens an insurer’s solvency. The practical consequence for the defense: the same conduct may be chargeable in two systems with different penalties, procedures, and plea dynamics, and where a matter can be steered — or whether both sovereigns pursue it — is a strategic question that deserves attention from the first day of an investigation.

How Federal Insurance Fraud Is Charged

Federal insurance fraud is built from the following statutes:

• Mail fraud, 18 U.S.C. § 1341. A scheme to defraud carried out through the mail. Because insurance claims, correspondence, checks, and policy documents routinely move by mail, courts have generally recognized that mailings connected to an insurance claim further an insurance fraud scheme. Mail fraud carries up to 20 years per count.
• Wire fraud, 18 U.S.C. § 1343. A scheme to defraud carried out through interstate wires — electronic claims, emails, fund transfers. It carries up to 20 years per count.
• Crimes by persons in the business of insurance, 18 U.S.C. § 1033. This statute targets false material statements made with intent to deceive insurance regulators, false entries, and the willful embezzlement or misappropriation of an insurer’s funds by its officers, directors, agents, or employees. Section 1033(e) separately makes it a crime — punishable by up to 5 years — for anyone with a felony conviction involving dishonesty or breach of trust to willfully work in the business of insurance without the written consent of a state insurance regulator, and for an insurance business to willfully permit it. Civil penalties and injunctions are available to the government under the companion statute, 18 U.S.C. § 1034.
• Health care fraud, 18 U.S.C. § 1347. Fraud against a health care benefit program, including private health insurers, is charged under its own statute.
• Conspiracy, 18 U.S.C. § 371. An agreement to commit any of these offenses, common in organized claim-fraud rings.

The choice of statute shapes the elements and the exposure. Section 1033 applies only to people “engaged in the business of insurance” — a defined term tied to the writing of insurance or the reinsuring of risks by an insurer — and how far that definition stretches is contested ground. In United States v. Renzi, 769 F.3d 731 (9th Cir. 2014), the Ninth Circuit read it to cover an insurance agency that marketed policies, collected premiums, and was authorized to bind an insurer to coverage, holding the definition reaches insurers, their officers, directors, agents, and employees, and those performing acts necessary or incidental to writing insurance. A concurring judge would have read the term more narrowly, and whether a particular broker, adjuster, or other industry participant falls inside the definition remains a genuinely litigable question. Claim-side schemes by outsiders, by contrast, are the province of the mail and wire fraud statutes.

Applied Insight: Whether a defendant is “in the business of insurance” under § 1033 is a real, litigable question. The statutory definition is narrow, and not everyone connected to the industry falls within it. Pinning down which statute actually fits the conduct — and whether it fits at all — is an early, valuable step in the defense.

What the Government Must Prove

For mail and wire fraud, the government must prove a scheme to defraud and the specific intent to defraud, together with the use of the mail or interstate wires to further the scheme. The mailing or wire need not itself be false. In Schmuck v. United States, 489 U.S. 705 (1989), the Supreme Court held that even an innocent, routine mailing satisfies the element so long as it is “incident to an essential part of the scheme” — which is why ordinary claim correspondence, premium notices, and settlement checks so often supply the federal hook in insurance cases. The flip side matters for the defense: a mailing that merely happens after a completed fraud, rather than in execution of it, cannot support a count, and count-by-count scrutiny of the charged mailings and wires is a standard part of our review.

Under 18 U.S.C. § 1033, the elements depend on the subsection charged. For false statements, the government must prove that a person engaged in the business of insurance, whose activities affect interstate commerce, knowingly and with intent to deceive made a false material statement — for example, in financial reports or documents presented to an insurance regulator. For misappropriation, it must prove that an officer, director, agent, or employee of such a person willfully embezzled or misappropriated the insurer’s funds.

Across all of these statutes, the decisive element is fraudulent intent. The government must prove the defendant knowingly set out to deceive — not that a claim was generous, that an estimate was high, or that a policyholder and an insurer simply disagreed. Evidence of good faith, of accurate disclosure, and of reasonable reliance on others bears directly on the absence of that intent.

What Recent Fraud Rulings Mean for Insurance Cases (2023–2026)

The Supreme Court has spent the past several terms redrawing the outer boundaries of the mail and wire fraud statutes, and because those statutes carry most federal insurance fraud prosecutions, the changes land here directly. Ciminelli v. United States, 598 U.S. 306 (2023), confined the statutes to schemes aimed at traditional money or property and abolished the “right to control” theory. A staged loss or inflated claim plainly targets an insurer’s money, so Ciminelli will not unwind the classic claim-fraud case — but prosecutions framed around depriving an insurer or regulator of accurate information, honest claims handling, or oversight authority are now vulnerable, and indictment language deserves a hard read on exactly this point.

Kousisis v. United States, 605 U.S. 114 (2025), pushed in the government’s direction on one axis while tightening another: a fraud conviction can stand even where the victim suffered no net pecuniary loss, but the misrepresentation must be material — it must go to something that genuinely mattered to the decision to issue the policy or pay the claim. In application-fraud and premium-fraud cases, that puts the spotlight on underwriting practice: if the carrier would have issued the same policy on the same terms regardless of the challenged answer, materiality is in real doubt. We treat these decisions as a checklist and run every charged count through them before the first motion is drafted.

Common Insurance Fraud Allegations

Federal insurance fraud prosecutions tend to follow recognizable patterns. Understanding how the government frames a fact pattern helps shape the defense:

• Staged or fabricated losses. Claiming an accident, theft, or loss that did not occur, or was deliberately caused.
• Arson for profit. Causing a fire to collect on a property policy — frequently charged together with arson and conspiracy.
• Inflated claims. Exaggerating the value of a genuine loss, or adding pre-existing damage to a real claim.
• Application fraud. Misrepresenting material facts — health, property condition, prior losses, or occupancy — to obtain a policy or a better rate.
• Premium fraud. Misrepresenting payroll, classifications, or risk to reduce workers’ compensation or other premiums.
• Agent and broker fraud. Pocketing premiums, selling fictitious coverage, or churning policies for commissions.
• Adjuster and public-adjuster fraud. Manipulating loss valuations or steering inflated claims for a share of the proceeds.
• Regulatory false statements. Misstating an insurer’s financial condition to state regulators under § 1033.

In every pattern, the government must prove knowing fraud rather than a dispute or an error. The defense scrutinizes the claim file, the policy, the communications, and what each individual defendant actually knew and represented.

Applied Insight: Inflated-claim cases are especially fact-sensitive. The difference between an aggressive but honest valuation of a real loss and a fraudulent overstatement often comes down to documentation — estimates, photographs, repair records, and contemporaneous communications. A defense that builds out that record can reframe what the government calls fraud as a good-faith valuation dispute.

Penalties for Federal Insurance Fraud

The exposure is serious. Mail fraud and wire fraud each carry a statutory maximum of up to 20 years per count, and indictments frequently charge a separate count for each mailing or wire. Offenses under 18 U.S.C. § 1033 generally carry up to 10 years; where the conduct jeopardized the safety and soundness of an insurer and was a significant cause of the insurer’s insolvency, the maximum rises to 15 years. Conspiracy adds its own exposure.

As in other federal fraud cases, the advisory United States Sentencing Guidelines drive the actual sentence — our overview of the federal sentencing process explains how — and the loss amount is usually the dominant factor, along with the number of victims, the use of sophisticated means, and the defendant’s role. Restitution to the defrauded insurer and forfeiture of proceeds are standard. Where arson or endangerment is involved, additional enhancements and charges can apply.

Because loss drives the Guidelines, a careful, well-documented loss analysis is often the most consequential part of a sentencing defense — distinguishing the legitimate value of a real loss from the disputed amount, separating intended from actual loss, and accounting for any payments returned.

Defenses to Insurance Fraud Charges

No two insurance fraud cases are alike, and no lawyer can promise a result. But several defense themes recur, and matching them to the evidence is the core of building a strategy:

• Lack of fraudulent intent. The claim, application, or statement reflected an honest belief or an error — not a knowing scheme to deceive.
• Genuine claim dispute. The matter is a good-faith disagreement over coverage, causation, or valuation, properly resolved through the claims process rather than the criminal law.
• Good-faith valuation. An aggressive but sincere estimate of a real loss is not fraud.
• No material misrepresentation. The challenged statement was accurate, was immaterial, or did not affect the insurer’s decision.
• Not in the business of insurance. For § 1033 charges, the defendant did not fall within the statute’s narrow definition.
• Reliance on others. Good-faith reliance on an agent, adjuster, contractor, or counsel can negate intent.
• Insufficient federal nexus. The proof fails to establish the use of the mail or interstate wires, or another required federal element.
• Sentencing and loss challenges. Even where conviction is likely, contesting loss and enhancements can sharply reduce exposure.

The right combination depends entirely on the claim file and the facts. Our role is to test the government’s proof element by element, develop the favorable record, and press every legitimate defense — during the investigation, in pretrial motions, at trial, and on appeal.

How Insurance Fraud Investigations Begin

Insurance fraud investigations often begin with the insurer itself. A carrier’s special investigations unit may flag a claim, deny it, and refer the matter to a state fraud bureau or to federal authorities. Investigations also start from a grand jury subpoena, an FBI interview, a state regulator’s referral, a whistleblower, or a cooperating witness from an organized claim-fraud ring.

The early steps matter. Statements made to an insurer’s investigator — including examinations under oath taken as part of the claims process — can later be used in a criminal case. If you sense that a claim inquiry has turned toward potential fraud, or you receive a subpoena or an agent’s call as part of a federal investigation, preserve every document, decline to give informal explanations, and consult experienced federal defense counsel before proceeding. Insurance fraud turns on intent, and an off-the-cuff account can be used against you.
