⚠️ Important Disclaimers

  • • Providers listed as “not yet charged” have NOT been accused of fraud by any authority.
  • • Statistical flags indicate unusual patterns that may have legitimate explanations.
  • • This analysis is journalism, not law enforcement.
  • • Our data covers 2014–2023. Enforcement actions occurred in 2025.

The Vindication

We built a fraud detection algorithm. We ran it on ten years of public Medicare data. It flagged 500 providers whose billing patterns were statistical outliers — impossible patient volumes, extreme billing concentrations, suspicious markup ratios, and growth curves that defied explanation.

We published the results. We named names. We showed our work. And then we waited.

In June 2025, the Department of Justice announced the largest healthcare fraud enforcement action in history: 324 defendants charged across the country in schemes totaling $14.6B in alleged fraud.

Multiple of our top-flagged providers were among those charged. Our algorithm — built entirely from public data — identified the same patterns that federal investigators spent years uncovering.

The Arizona Ring — Our Data Saw It

Our Arizona Wound Care Ring investigation identified 23 nurse practitioners in the Phoenix metro area billing Medicare for skin substitute products at rates that were statistically impossible. All shared a nearly identical 1.28x markup ratio — the fingerprint of coordinated billing.

We were right. In June and July 2025, the DOJ charged multiple providers from our flagged list in what prosecutors described as a $1 billion amniotic wound allograft scheme.

The Ringleader: Jeffrey Amos King

Sentenced to 14 years in federal prison (October 2025) for orchestrating the scheme. King recruited nurse practitioners to bill Medicare for unnecessary skin substitute products while he collected kickbacks.

The 1.28x Markup: The Coordinated Billing Protocol

Every provider in this ring shared a nearly identical 1.28x markup ratio — the ratio between what they charged Medicare and what they were paid. This isn't coincidence. This is a coordinated billing protocol: the same software, the same instructions, the same scheme. Our algorithm flagged this identical ratio as statistically anomalous before the DOJ announced charges.

The COVID Test Pharmacy — Caught

VRA Enterprises

Tampa, FL

SETTLED

Our Flag

#1 COVID test biller: $75.8M

DOJ Action (Nov 2025)

Settled for $17.0M

VRA Enterprises was the #1 COVID test biller in our entire dataset — $75.8M from a single Tampa pharmacy. Our COVID Test Scheme investigation flagged the extreme volume as statistically impossible.

In November 2025, the DOJ announced that VRA agreed to pay over $17.0M to resolve False Claims Act allegations. According to prosecutors, VRA billed Medicare for “COVID tests not provided to beneficiaries or sent months after billing Medicare.”

Merry Taheri — The Mystery

Services/Day

Watchlist Rank

#1

Merry Taheri was the #1 provider on our watchlist — $12.1M in COVID test billing, 4.1K services per day. Our algorithm gave her a risk score of 96 out of 100.

Then the story got strange. An investigation by WTHR (Indianapolis) found Taheri claiming that someone was “fraudulently using her name” to send COVID tests and bill Medicare. Patients across the country reported receiving unsolicited test kits billed to Taheri's NPI.

Meanwhile, Taheri is running for the California State Assembly — while her NPI shows $12.1M in Medicare billing.

Status: No charges filed. Under investigation? Identity theft victim? We genuinely don't know. But the billing happened, and someone got paid.

Still Out There — Providers Not Yet Charged

⚠️ The following providers have NOT been accused of fraud by any authority. Statistical flags indicate unusual patterns that may have legitimate explanations. Inclusion here is based solely on public Medicare billing data.

These providers show the same statistical patterns as the convicted Arizona ring — extreme billing concentration in wound care or COVID tests, impossible patient volumes, suspicious growth curves — but have not been charged.

What This Means

The Methodology Works

Peer comparison + volume anomalies + billing concentration = real fraud signals. We proved it.

  1. Statistical analysis CAN identify fraud patterns before enforcement catches up. Our algorithm used only public data. No subpoenas. No wiretaps. No informants. Just math applied to billing records that anyone can download.
  2. The data is public — anyone can verify our findings. Every number in this article comes from CMS's Medicare Provider Utilization and Payment Data. Download it yourself. Run the numbers. You'll find what we found.
  3. We flagged 500 providers. At least 6 were subsequently charged. How many more will be? The DOJ's June 2025 action was massive, but it barely scratched the surface of what the data shows. 494 of our flagged providers have not been charged. Some may be innocent. Some may just not have been caught yet.
  4. This validates the methodology. Peer comparison, volume anomaly detection, markup ratio analysis, billing concentration metrics — these aren't just academic exercises. They produce actionable intelligence that matches what billion-dollar federal investigations find.

How to Report Suspected Fraud

If you have information about healthcare fraud, waste, or abuse, you can report it:

OIG Hotline

⚠️ Important Context

All data on this page comes from publicly available CMS Medicare payment records. Unusual billing patterns may reflect legitimate medical practices (such as high-volume drug administration where each unit is counted as a separate service), data reporting differences, or group practice billing. Inclusion on this page does not constitute an accusation of fraud or wrongdoing. Only law enforcement and regulatory agencies can determine whether billing patterns represent fraud. Providers flagged by our statistical model have billing patterns similar to previously convicted providers, but many may have perfectly legitimate explanations.
