Tri-City Cardiology: The Measurements Behind Allegedly Unnecessary Vein Ablations

In the Tri-City Cardiology vein ablation settlement, the practice and three physicians agreed to pay $4.75 million to resolve allegations of medically unnecessary perforator-vein ablations. The government alleged that incorrect measurements and medical records made the procedures look justified. If you took those measurements, worked with the patient histories or handled the resulting claims, you may recognize where the clinical facts and the billing story separated.

The Justice Department announced the civil settlement on March 12, 2026. Tri-City provides cardiology and vascular services in the Phoenix, Arizona, metropolitan area, and the physicians who settled were shareholders who performed vein ablations. The practice and physicians denied the government’s account even as they agreed to pay.

What the Government Alleged

The government alleged that the physicians knowingly performed unnecessary perforator-vein ablations from January 1, 2017, through April 27, 2022. Perforator veins are small veins connecting the deep and superficial veins in the legs, and they require treatment only in certain circumstances. The alleged medical necessity fraud concerned the facts used to make those circumstances appear present.

The settlement agreement describes the alleged misrepresentations as incorrect measurement or documentation of:

• Outward blood flow: how long the outward flow lasted.
• Vein diameter: the size of the vein selected for treatment.
• Patient symptoms: the symptoms recorded to support the procedure.
• Conservative therapy: the measures documented in the patient’s treatment history.

Those details supplied the apparent justification for the ablations, according to the government. The allegation reached both the measurement itself and what went into the medical record. Someone can know how a measurement was taken, how a result was entered, or how the patient’s history became the justification for treatment.

We see the problem in the government’s account: a record meant to explain why a patient needed treatment allegedly supplied a false reason to perform it. For taxpayers, that reason was used to justify a request to pay for the procedure. For the patient, it concerned whether the procedure should happen at all.

The Measurement, the Chart and the Claim

The central evidence comparison is between the source measurements, the clinical record and the claim for payment. We connect the original finding to the entry used to justify treatment, then to the procedure and government bill. For flow and diameter, that means understanding where the recorded value came from; for symptoms and conservative care, it means understanding whose account supplied the history.

Medicare’s medical-record review guidance requires the record’s author to remain identifiable. For someone who works with the records, authorship helps connect the clinical information to the person who recorded it. We examine that connection alongside the measurement and the claim it supported.

A billing record tells us what the practice asked the program to pay for. The underlying clinical material lets us examine the reason it gave for doing the work. Our review of physician billing evidence brings those records together with the insider who can explain how the information moved between them.

A 2020 article in the Journal of Forensic and Investigative Accounting, A Forensic Accountant’s Guide to the Most Potent Federal Laws Used Against Healthcare Fraud, connects Medicare’s requirement for reasonable and necessary care to the request for payment. Applied here, that means following an allegedly incorrect measurement through to the government payment it was used to request.

Physician Owners and Control of the Record

The physicians’ role as shareholders puts the practice’s ownership alongside its clinical work. The agreement identifies them as both owners and performers of vascular procedures, while alleging that the practice and physicians submitted or caused the government claims. For an insider, the useful question is who controlled the information supporting those claims.

The chapter Implementing a Physician Practice Compliance Program, published in Jones and Bartlett Publishers’ Health Care Administration: Managing Organized Delivery Systems in 2011, explains why ownership matters to that question. It puts the owners’ influence over the practice plainly:

Understanding the number means understanding how the practice handled it: who produced the measurement, who entered the history and who relied on it when billing. If someone questioned an inconsistency, their account may also explain who received the concern. Those are connections we examine with an insider who knows the practice’s work.

The Government Programs Behind the Settlement

The agreement covered claims to Medicare, Medicaid, TRICARE and the Department of Veterans Affairs. The government alleged that Tri-City and the physicians submitted or caused claims seeking reimbursement for the unnecessary ablations.

The agreement allocates $4,606,247 of the settlement to the United States and $143,753 to Arizona. The Justice Department’s Civil Division and the U.S. Attorney’s Office for the District of Arizona obtained the resolution through a coordinated effort, with assistance from the Health and Human Services Office of Inspector General.

When the Clinical Reason Reaches the Government Bill

An insider’s knowledge can connect a medical record to the decisions that produced a government claim. In a vein-ablation matter, that may be the person who understands the source measurement, recognizes the patient’s actual history or knows how the practice handled a disputed entry. We work with that knowledge to assess a physician practice qui tam case.

A whistleblower case under the False Claims Act can pay 15% to 30% of what the government recovers. The work starts with the clinical facts and the claims they supported. Our role is to connect your knowledge of the health care practice to a case that explains who made the decisions and how public money followed them.
