Laboratory fraud is the knowing submission of false or misleading billing information by a clinical laboratory to collect payments it isn’t entitled to receive from Medicare, Medicaid, or private insurers. The consequences stack across civil, criminal, and administrative tracks at once: per-claim civil penalties now exceeding $14,000, prison sentences reaching 10 years or more, and exclusion from federal healthcare programs that typically ends the business. Most major cases begin with an insider who files a sealed whistleblower suit and collects a share of the recovery.
What Counts as Laboratory Fraud
The line between fraud and an honest billing mistake is intent. Under the False Claims Act, a laboratory acts “knowingly” if the person submitting the claim knew the information was wrong, deliberately avoided learning the truth, or acted with reckless disregard for accuracy. None of those states of mind require proof of a specific plan to defraud anyone.1Office of the Law Revision Counsel. 31 USC 3729 – False Claims
Most enforcement actions start from a single Medicare coverage rule: the program only pays for tests that are reasonable and necessary to diagnose or treat an illness or injury.2Centers for Medicare & Medicaid Services. Medicare Coverage of Items and Services A claim for a test that doesn’t meet that standard is potentially fraudulent, and the “reasonable and necessary” question is where investigators usually start.
The Schemes That Trigger Enforcement
A handful of patterns recur in federal cases. Billing manipulation is the simplest. Upcoding means submitting a billing code for a more expensive test than the one performed. Unbundling means breaking a test panel into its component parts and billing each separately instead of using the single, lower-cost panel code. Both inflate what the laboratory collects per patient.
A second pattern involves tests that serve no clinical purpose. Laboratories sometimes design requisition forms so that a physician ordering one routine test unknowingly triggers claims for a battery of expensive add-ons. Large-panel allergy screenings, genetic tests, and comprehensive toxicology panels ordered without a specific medical reason are frequent enforcement targets. A Maryland-based billing company paid over $300,000 to resolve allegations that it caused Medicare claims for unnecessary respiratory pathogen panels tacked onto COVID-19 tests for elderly patients.3Office of Inspector General, U.S. Department of Health and Human Services.

The most dangerous scheme is drylabbing: reporting analytical data on samples that were never actually tested. Beyond the financial fraud, drylabbing produces unreliable results that may drive real treatment decisions, which is what pulls these cases into the more severe criminal exposure described below.
Civil Penalties Under the False Claims Act
The government’s primary civil tool is the False Claims Act, 31 U.S.C. § 3729. It imposes liability on anyone who knowingly submits, or causes someone else to submit, a false claim for payment to the federal government. Because “knowingly” reaches deliberate ignorance and reckless disregard, turning a blind eye to billing irregularities is enough.1Office of the Law Revision Counsel. 31 USC 3729 – False Claims
The numbers add up fast. Each false claim triggers a civil penalty that the statute originally set at $5,000 to $10,000 but that adjusts for inflation every year. For penalties assessed after July 3, 2025, the inflation-adjusted range is $14,308 to $28,619 per claim.4Federal Register. Civil Monetary Penalties Inflation Adjustments for 2025 On top of the per-claim penalty, the violator owes three times the government’s actual damages. A laboratory that submitted thousands of fraudulent claims over several years can face liability in the tens or hundreds of millions of dollars.
The treble multiplier drops to double damages only in a narrow circumstance: the violator self-reported within 30 days, fully cooperated with investigators, and had no knowledge of any existing investigation at the time of the disclosure.1Office of the Law Revision Counsel. 31 USC 3729 – False Claims
Kickbacks and Self-Referral: Three Statutes to Know
Three separate laws govern the money and referrals that flow around a laboratory. They overlap, and a single arrangement can violate more than one.
The Stark Law
The Stark Law, 42 U.S.C. § 1395nn, prohibits a physician who has a financial relationship with a laboratory from referring Medicare patients to that laboratory unless a specific exception applies. The laboratory cannot bill Medicare for any test resulting from a prohibited referral. Stark is a strict-liability statute, so intent is irrelevant: if the referral violates the rule, the consequences follow.5Centers for Medicare & Medicaid Services. Physician Self-Referral Medicare denies payment and the lab must refund amounts already collected. Knowingly submitting a claim for an improperly referred service carries a civil penalty of up to $15,000 per claim, and arrangements designed to circumvent the law carry penalties of up to $100,000 per arrangement.6Office of the Law Revision Counsel. 42 US Code 1395nn – Limitation on Certain Physician Referrals
The Anti-Kickback Statute
The Anti-Kickback Statute, 42 U.S.C. § 1320a-7b, makes it a felony to knowingly pay or receive anything of value in exchange for referring patients or generating business payable by a federal healthcare program. For labs, this covers payments to physicians, sales representatives, or marketers for steering specimens, along with free supplies, below-cost processing, and other inducements. A conviction carries a fine of up to $100,000 and up to 10 years in federal prison per violation, plus mandatory exclusion from federal healthcare programs for a minimum of five years.7Office of Inspector General, U.S. Department of Health and Human Services. Exclusions Authorities
EKRA
The Anti-Kickback Statute only reaches payments tied to federal programs. The Eliminating Kickbacks in Recovery Act, 18 U.S.C. § 220, closed that gap for laboratories in 2018. EKRA makes it a federal crime to pay or receive kickbacks for referring patients to a laboratory regardless of who pays for the test, reaching private insurance and cash-pay arrangements. Penalties run up to $200,000 per occurrence and up to 10 years in prison. EKRA currently applies only to laboratories, recovery homes, and clinical treatment facilities.8Office of the Law Revision Counsel. 18 USC 220 – Illegal Remunerations for Referrals to Recovery Homes, Clinical Treatment Facilities, and Laboratories
Criminal Exposure
Beyond the healthcare-specific statutes, prosecutors regularly charge laboratory fraud under general federal criminal laws. The most directly applicable is 18 U.S.C. § 1347, the federal health care fraud statute, which makes it a crime to knowingly execute a scheme to defraud any health care benefit program. A conviction carries up to 10 years in prison. If the fraud results in serious bodily injury to a patient, the maximum rises to 20 years. If a patient dies as a result of the fraud, the sentence can reach life imprisonment.9Office of the Law Revision Counsel. 18 USC 1347 – Health Care Fraud That escalation matters most for drylabbing, where fabricated results can produce wrong diagnoses and harmful treatment.
Prosecutors also use the mail and wire fraud statutes, 18 U.S.C. § 1341 and § 1343. Each count carries up to 20 years in prison.10Office of the Law Revision Counsel. 18 US Code 1341 – Frauds and Swindles11Office of the Law Revision Counsel. 18 USC 1343 – Fraud by Wire, Radio, or Television Because virtually every modern billing interaction travels electronically, wire fraud counts stack easily onto a laboratory fraud indictment, and the practical exposure can dwarf what any single statute authorizes on its own.
Exclusion From Federal Healthcare Programs
Administrative exclusion is often the penalty laboratory operators fear most, because it ends the business rather than just costing money. The HHS Office of Inspector General maintains a list of excluded individuals and entities, and any lab on that list cannot bill Medicare, Medicaid, TRICARE, or any other federal health program.
Exclusion comes in two flavors. A felony conviction for healthcare fraud triggers mandatory exclusion for a minimum of five years, with no discretion to waive or reduce the period. A misdemeanor conviction for healthcare fraud carries a baseline permissive exclusion of three years, and the OIG has discretion over whether to impose it. Both are governed by 42 U.S.C. § 1320a-7.7Office of Inspector General, U.S. Department of Health and Human Services. Exclusions Authorities For a laboratory that depends on Medicare volume, even a three-year permissive exclusion is usually enough to force closure. A five-year mandatory period after a felony conviction makes any comeback nearly impossible.
If You’re the One Reporting It
Most major laboratory fraud cases begin with an insider. The False Claims Act’s qui tam provision, 31 U.S.C. § 3730, lets any private citizen with knowledge of fraud against the government file suit on the government’s behalf. The person filing, called the relator, submits the complaint under seal so the laboratory doesn’t learn about it while the Department of Justice investigates and decides whether to intervene.
The financial rewards are substantial. If the government takes over the case, the relator receives between 15% and 25% of the recovery, with the exact percentage depending on how much the whistleblower contributed. If the government declines to intervene and the relator prosecutes alone, the share rises to between 25% and 30%.12Office of the Law Revision Counsel. 31 US Code 3730 – Civil Actions for False Claims Laboratory fraud settlements routinely reach the millions, so those percentages translate into significant sums.
The FCA also protects against retaliation. An employee, contractor, or agent who is fired, demoted, suspended, harassed, or otherwise punished for reporting fraud is entitled to reinstatement with full seniority, double back pay plus interest, and compensation for special damages including litigation costs and attorney fees. A retaliation claim must be filed within three years of the retaliatory act.12Office of the Law Revision Counsel. 31 US Code 3730 – Civil Actions for False Claims The double-back-pay provision is deliberately punitive. Congress wanted to make it more expensive to retaliate against a whistleblower than to let the investigation proceed.
