If you suspect that a healthcare provider, supplier, or employer is billing Medicare improperly, you may be considering a whistleblower claim under the federal False Claims Act (31 U.S.C. 3729-3733). This law allows private individuals, known as relators, to file qui tam lawsuits on the government's behalf. One of the most important practical questions is how much time you have to act. The answer is not a single simple deadline, but a set of rules that depend on when the fraud occurred and when the government learned about it.
The Basic Six-Year Filing Window
Under the False Claims Act, a qui tam lawsuit generally must be filed within six years from the date the violation occurred. This is the primary deadline that applies in most cases. If a provider submitted false claims to Medicare in 2020, for example, the six-year clock would generally run from that submission. Because Medicare fraud often involves repeated billing over many months or years, each individual false claim can start its own six-year period.
The Alternative Three-Year Rule and the Ten-Year Cap
Congress also created a second, longer path for filing. A claim may be brought within three years from the date the government knew or should have known about the facts material to the violation. This alternative rule can extend the deadline beyond six years, but it is subject to an absolute outer limit: no qui tam action may be filed more than ten years after the violation occurred. In practice, this means that very old fraud is almost always time-barred, even if the government only recently discovered it.
Why Timing Matters in Qui Tam Cases
Understanding these deadlines is critical because qui tam complaints are filed under seal. That means the case remains confidential for a period while the Department of Justice and other agencies, such as the HHS Office of Inspector General, investigate. The government must decide whether to intervene and take over the case. If the government intervenes, a relator generally receives 15 to 25 percent of the recovery. If the government declines to intervene and the relator proceeds on their own, the relator's share is generally 25 to 30 percent. In either scenario, a liable party can owe up to three times the government's damages plus per-claim civil penalties that are adjusted for inflation each year.
Because the investigation and intervention process can take time, waiting too long to file can jeopardize a claim. The filing deadline applies to the relator's initial complaint, not to the eventual resolution of the case. If you believe you have evidence of fraud, it is generally wise to consult with an attorney experienced in qui tam matters early, so that the necessary steps can be taken within the applicable window.
Protection Against Retaliation
Concern about losing your job should not, by itself, prevent you from reporting fraud. Section 3730(h) of the False Claims Act protects employees, contractors, and agents from retaliation for lawful acts taken to further a qui tam action or other efforts to stop a violation. Remedies for retaliation can include reinstatement, double back pay, and compensation for special damages. These protections apply regardless of whether the underlying qui tam case ultimately succeeds.
Where to Report Suspected Fraud
You do not need to file a lawsuit to report suspected Medicare fraud. Tips can be submitted directly to the HHS-OIG hotline at 1-800-HHS-TIPS (1-800-447-8477). Medicare beneficiaries who suspect billing irregularities can also call 1-800-MEDICARE. Reporting through these channels can alert the government to a problem even if you are not ready to pursue a qui tam case.
Statutes of limitations exist to encourage timely action, but they also create traps for the unwary. Knowing the six-year rule, the three-year alternative, and the ten-year cap can help you decide whether to move forward and how quickly you need to act.
