The Government’s False Claims Act Investigation: What Investigators Need to See

A False Claims Act investigation by the Justice Department examines whether a business knowingly made false claims involving government money, using documents, witness accounts and payment records to test the allegations. An insider may know who chose the practice, which records explain it and what management understood when the business billed the government or kept money it owed. Those details connect the government’s view of the payments to the decisions inside the business.

Who Investigates False Claims Act Allegations?

The Department of Justice handles the federal civil case, working with the agency whose money or program is involved.

The Justice Manual calls for the U.S. Attorney’s Office and the Fraud Section to confer when a whistleblower complaint arrives and decide how to handle it. The department also seeks the affected agency’s views during the investigation, including whether the alleged representations were false and whether they mattered to payment.

Agency inspectors general can take part in the investigative work. In a criminal case against a company owner described in HHS-OIG’s Medicaid enforcement report, California’s Medicaid Fraud Control Unit worked with the FBI, HHS-OIG and the Veterans Affairs inspector general.

For an insider, the agency’s involvement matters because the payment has a context. A contract specification, a billing requirement or a program’s eligibility rules can explain why the government paid and what the business represented to obtain that money.

What Does the Government Need to Establish?

The investigation connects the alleged falsehood to a claim or money owed to the government, what the business knew, why the information mattered to payment and any resulting loss.

False billing can misstate what was supplied, how much was supplied or who supplied it. A certification can misrepresent compliance with a requirement that matters to payment. An investigation can also concern money the business knowingly and improperly kept instead of paying the government.

Knowledge concerns what people understood when the business acted. Internal instructions, audit findings, warnings and communications can put that understanding beside the claim. We connect those records to the people making the decisions and the payments affected.

Investigators also examine whether the false information mattered to the agency’s payment decision. The agency’s own records can show what it knew about the conduct and what it did about payment.

The Documents Behind the Claim

Documentary review reaches beyond the complaint to the records that can support or test it. In a qui tam case, the government receives both the complaint and a written disclosure of the whistleblower’s material evidence and information under the False Claims Act.

The payment system determines which records matter. Healthcare reimbursement can involve hospital billing and cost reports. A contractor’s representations may sit in product qualification records or certified pricing data. Research funding connects the work described to the grant. An importer’s records instead concern duties owed to U.S. Customs and Border Protection. The records follow how government money changed hands or went unpaid.

The Justice Manual identifies useful cooperation: documents and their origins, people familiar with company operations, facts tied to specific sources and information in its original electronic format.

A spreadsheet’s contents and the explanation of where those contents came from belong together. We want to understand the underlying work, who supplied the information and how it became the number or certification the government received.

What Was Missing From the File?

A whistleblower complaint against Abbott Laboratories alleged that the company physically removed rework and sampling records before giving a batch record to an FDA investigator. It also alleged that Abbott removed rework and sampling records normally kept in complete batch files to create the impression that they were routinely stored separately.

We see the absurdity in that allegation: making a file look complete by taking records out. We would want to know who decided the investigator should see less than the business kept. Someone who knows how the business keeps its records can explain what a seemingly complete file leaves out.

Interviews Connect the Records to the Work

Interviews can establish who knows the operations, policies and conduct behind the documents.

An employee’s knowledge of the work can connect a billing entry to an instruction, or identify the person who understands how a company system produced a report. A document identifies what was recorded. The person who worked with it may explain how it got there. We develop those connections with the whistleblower.

How Data Analysis Fits the Investigation

Data analysis can identify payment patterns for investigators to examine alongside program rules and other evidence. In its May 2026 benefits-fraud announcement, the Civil Division described seeking agency information and data analysis to help corroborate whistleblower allegations about federally funded benefits programs administered by states.

The department’s April 2026 FOCUS announcement addressed companies and individuals who analyze public government data for signs of fraud. It emphasized explaining why the data signals reliably correlate with fraud, familiarity with program rules and the rigor of the analysis.

For someone inside the business, the useful connection is between the pattern and the practice that produced it. We examine how your account of the operation fits the claims data. A billing pattern becomes much more informative when the people behind it and the instructions governing it come into view.

What Is a Civil Investigative Demand?

A civil investigative demand is a compulsory request for information relevant to a False Claims Act investigation. It can require documents, written answers to questions, sworn oral testimony or a combination of those forms of evidence.

Under the law authorizing civil investigative demands, the government can use this tool before it decides whether to join a whistleblower case. The documents and testimony help the government make its assessment.

Investigation and the Intervention Decision

The government can investigate a whistleblower’s allegations before deciding whether to take primary responsibility for the case.

Intervention means the government takes the lead in pursuing the case, while the whistleblower, known as the relator, remains a party. The investigation supplies information for that decision. Requests for records, interviews and consultation with an agency are part of gathering and evaluating evidence.

The Congressional Research Service’s 2009 report, Qui Tam: The False Claims Act and Related Federal Statutes, explains the arrangement behind this division of work: private parties can bring cases in the government’s name while the government retains authority over how those cases proceed.

Can I Proceed If the Government Declines My Case?

Yes. The False Claims Act allows the whistleblower to continue the case when the government declines to take it over. We assess what that decision means for your case with False Claims Act whistleblower lawyers who know the program involved.

Related Investigations Can Examine the Same Conduct

A civil False Claims Act investigation can run alongside criminal, regulatory or administrative work. The Justice Manual calls for coordination among those proceedings and for investigative work on the government’s loss.

The benefits-fraud initiative makes the division visible. It describes referrals for evaluation of potential criminal violations and sharing with the affected agency to assess administrative action. Meanwhile, the civil review seeks information that can corroborate the whistleblower’s allegations.

These offices may examine the same conduct for different purposes. We keep the civil claim, the agency’s findings and any criminal allegations distinct when assessing what the evidence supports.

Damages Analysis Follows the Payment

Damages analysis examines the loss the alleged conduct caused the government. The work depends on the payment terms, the goods or services promised, what the government received and the reason payment was improper.

For a contract, the comparison may concern the value promised against the value delivered, as the court explained in the Science Applications International Corp. case in 2010. In a health care program, a rule prohibiting payment for the claims can change that analysis even when services were delivered. What the government agreed to pay for matters to what it lost.

The Justice Manual identifies assistance in determining losses as useful cooperation. That connects the financial work to the investigation itself: the records supporting the allegation also help establish its financial reach.

A whistleblower case under the False Claims Act can pay 15% to 30% of what the government recovers. We assess the evidence and the payment connection with you, including what your knowledge adds when the government is already investigating.
