The Million-Dollar Club
47 AI-Flagged Providers Who Billed Over $1M Each — and Match the Pattern of Convicted Fraudsters
⚠️ Important Disclaimer: The providers identified in this analysis are flagged based on statistical patterns, not evidence of wrongdoing. High billing volume alone is not suspicious — many of these providers may serve large, complex patient populations. A high fraud probability score means billing patterns are mathematically similar to those of convicted fraudsters. No provider named here has been accused or charged with any crime unless otherwise noted.
Most of the 500 providers flagged by our AI model bill Medicare in the hundreds of thousands per year — enough to trigger statistical alarm bells, but not enough to stand out in raw dollar terms. Then there are the 47 who crossed the million-dollar threshold.
These aren't just providers with suspicious billing patterns. They're providers with suspicious billing patterns and massive volume. Collectively, they billed Medicare over $93.4M — an average of $2.0M each. Their average fraud probability score is 92.1%.
Not all big billers are fraudsters. Oncologists routinely bill millions due to expensive drug costs. Large group practices can legitimately bill tens of millions. But when a provider bills over $1 million and their billing pattern matches convicted criminals across every metric our model tracks — volume, markup, services per patient, geographic concentration — that's a different story.
📊 The Million-Dollar Club at a Glance
The Biggest Billers
At the top of the million-dollar club sits Terrance Hughes, an Illinois internist who billed Medicare $5.3M. That's more than six times the average for Internal Medicine providers — and his billing pattern matches convicted fraudsters with a 91.2% probability score.
Terrance Hughes
Internal Medicine
Highest total payments of any flagged provider — $5.3M from Medicare with a 4.12 services-per-beneficiary ratio
Remy Zockazock
Internal Medicine
South Florida internist with $4.1M in payments — high probability and high volume
Edwin Yau
Internal Medicine
California internist billing $3.8M — the state's highest-billing flagged provider
Chinh Mai
Internal Medicine
Texas internist with $3.3M and nearly 4 services per beneficiary — well above the specialty average
What Makes High-Volume Flagged Providers Different?
The million-dollar flagged providers aren't just scaled-up versions of typical suspicious billers. They have a distinct profile:
Million-Dollar Club (47 providers)
- • Avg payments: $2.0M
- • Avg markup ratio: 2.31×
- • Avg services/beneficiary: 3.64
- • 72% Internal Medicine
- • Concentrated in CA, FL, IL, TX
Other Flagged Providers (453)
- • Avg payments: $680.0K
- • Avg markup ratio: 2.15×
- • Avg services/beneficiary: 2.89
- • 51% Internal Medicine
- • More geographically dispersed
The million-dollar group has higher markup ratios, more services per beneficiary, and is even more concentrated in Internal Medicine than the broader flagged pool. They're not just billing more — they're billing differently. Higher intensity per patient, higher charges relative to what Medicare allows, and more services packed into each patient encounter.
Not All Big Billers Are Fraudsters — But These Match the Pattern
This is an important distinction. Medicare has thousands of providers who legitimately bill over $1 million per year. Oncologists administering chemotherapy drugs can bill $5–10M+. Large multi-provider group practices bill tens of millions. High-volume surgical practices serve hundreds of patients.
What sets the million-dollar club apart isn't the dollar amount — it's that these providers match convicted fraudsters across every dimension our model evaluates:
🚩 The Full Pattern Match
- ✓ Volume: High total services and beneficiary counts
- ✓ Markup: Charging 2–3× what Medicare allows (vs. 1.5× typical)
- ✓ Intensity: 3.5+ services per beneficiary (vs. 1.8 average)
- ✓ Specialty: Overwhelmingly Internal Medicine (72%)
- ✓ Geography: Concentrated in known fraud hotspot states
- ✓ Code distribution: Heavy on high-paying E&M codes
Each factor alone could be explained. All six together, matching the exact signature of convicted criminals? That's what our model is designed to detect.
The question isn't whether these providers are billing a lot of money. Plenty of legitimate providers do. The question is why their billing patterns look identical to people who went to prison.
