False Claims Act (FCA): Liability for False Medicare/Medicaid Claims
The False Claims Act (FCA, 31 U.S.C. 3729) is the government's primary tool against health-care fraud. It imposes liability on anyone who knowingly submits, or causes to be submitted, a false or fraudulent claim for federal payment. Penalties are treble (triple) the damages plus a per-claim civil penalty, and private whistleblowers can sue on the government's behalf.

What is the False Claims Act?
The FCA is the law behind most large health-care fraud recoveries. It makes it illegal to knowingly submit — or cause to be submitted — a false or fraudulent claim for federal funds, and it hits hard: treble damages (three times what the government lost) plus a civil penalty for each false claim. In a high-volume billing context, per-claim penalties alone can dwarf the actual overpayment.
It is the common enforcement endpoint for Stark, Anti-Kickback, and overpayment violations.
What is the "knowing" standard?
You do not have to intend fraud. "Knowingly" reaches actual knowledge, deliberate ignorance, and reckless disregard. That third category is the trap for billing operations: choosing not to look — never auditing high-risk codes, ignoring repeated NCCI denials, submitting modifier 59 as a habit — can itself satisfy the standard.
How do whistleblower cases work?
The FCA's qui tam provision lets a private relator — very often a current or former employee — sue on the government's behalf and collect a share of the recovery. The government can intervene or let the relator proceed alone. This is why a functioning compliance hotline and genuine non-retaliation practice are not optional: an internal report that gets buried can resurface as a federal lawsuit with the same facts.
What billing behaviors trigger the FCA?
- Services not rendered or upcoded to a higher level than documented.
- Unbundling to bypass NCCI edits without a supporting note.
- Insufficient documentation — billing what the record does not support (see medical record documentation).
- Retained overpayments past 60 days (reverse false claims).
- Kickback- or Stark-tainted claims, which are false as a matter of law.
The defense is boring but effective: accurate coding, complete documentation, prompt refunds, and self-audits driven by the OIG Work Plan.
Frequently asked questions
A claim is false if it is factually untrue (billing for a service not rendered) or legally false (billing for a service that violated an underlying rule, like a claim tainted by a kickback or unsupported by documentation). It also covers "reverse false claims" — knowingly avoiding an obligation to repay the government, which is how the 60-day overpayment rule connects to the FCA.
The FCA does not require specific intent to defraud. "Knowingly" includes actual knowledge, deliberate ignorance, and reckless disregard of the truth. So "we didn't check" or "we assumed it was fine" is not a defense — a billing operation that ignores obvious red flags or fails to audit known risk areas can meet the knowledge standard.
Qui tam lets a private person (a "relator," often an employee) file an FCA suit on behalf of the government and share in any recovery, typically 15-30%. Many health-care FCA cases start this way. That is why compliance, non-retaliation policies, and taking internal reports seriously matter — an ignored internal complaint can become a qui tam case.
