5 Signs of Medicare Fraud That Aren’t Just Billing Mistakes

Every healthcare billing system makes mistakes. Codes get transposed, claims get submitted twice by accident, a modifier gets left off. That's not what this is about. These are the real signs of Medicare fraud: the difference between an honest error and a pattern, which is something systemic, repeated, and designed to extract more money from Medicare or Medicaid than the government actually owes.

If you work in billing, coding, compliance, sales, or clinical care, you may already sense the difference. Here are five signs of Medicare fraud that consistently show up in real cases.

The 5 signs of Medicare fraud to watch for

1. Upcoding: billing for more than what happened

A patient comes in for a routine 15-minute visit, but it's billed as a complex, extended visit. A basic procedure gets billed under a code for a more involved one. Done occasionally, it might be a training issue. Done as a pattern — especially if leadership pushes it — it's fraud.

2. Phantom billing: charging for care that never happened

Claims submitted for tests, equipment, or visits that were never actually provided. This shows up in home health, durable medical equipment, and hospice fraud constantly: billing Medicare for a wheelchair, a nebulizer, or a home visit that simply never occurred.

3. Kickbacks and improper referrals

Payments disguised as “consulting fees,” “medical directorships,” or “speaker fees” that exist mainly to reward doctors for referrals or for prescribing a particular drug or device. The Anti-Kickback Statute and Stark Law exist precisely because this distorts medical decisions and drives fraudulent billing.

4. Unbundling and unnecessary services

Billing separately for procedures that should be billed together at a lower combined rate (unbundling), or ordering tests and procedures that have no medical justification — purely to generate billable claims. Watch for a pattern of the same unnecessary test being ordered for nearly every patient.

5. Altered or backdated records

Documentation that gets “cleaned up” after the fact to match what was billed, rather than what actually happened, especially if you're asked to change or backdate notes yourself. This is often the clearest sign that the people involved know exactly what they're doing.

You don't need to build the whole case yourself

If you're recognizing more than one of these patterns where you work, that's worth a confidential conversation. You don't need a fully assembled case, a whistleblower attorney's job is to evaluate what you know, determine whether it points to real, recoverable fraud, and help you decide what, if anything, to do next.

Frequently asked questions

What if I'm not totally sure it's fraud and not just sloppy billing?

That's exactly what a confidential consultation is for. Bring what you've observed, even if you're unsure, we'll help you assess whether it rises to the level of a real case.

Does the fraud have to be happening right now?

No. Past fraud can still be actionable, subject to the statute of limitations (generally six years from the violation, sometimes longer).

What size of case are you looking for?

We focus on significant, well-documented fraud, schemes affecting multiple patients, providers, or billing cycles, where federal recovery is realistic. If the scale is large, it's worth a call.
