Guam Medical Transport: Dialysis Claims and Employees’ Ignored Concerns

In the Guam Medical Transport fraud case, two former owners and an employee admitted in their guilty pleas that they billed Medicare and TRICARE for medically unnecessary dialysis ambulance rides. They knew many patients did not qualify for ambulance transportation. They directed employees to remove references to patients’ ability to walk from internal documents. They also admitted knowing about employees’ billing concerns and failing to address them. We see a company asking the paperwork to conceal the very condition the payment decision depended on.

Guam Medical Transport was an ambulance provider headquartered in Guam. Its scheduled, non-emergency trips carried patients with end-stage renal disease to and from dialysis treatment. The defendants’ plea admissions covered conduct from approximately March 11, 2010, through approximately March 21, 2014.

The FBI, IRS Criminal Investigation and the Department of Health and Human Services Office of Inspector General investigated the case. The Justice Department’s Criminal Division and the U.S. Attorney’s Office for Guam and the Northern Mariana Islands prosecuted it. The admissions described below came from the former owners and employees in that criminal case.

The Dialysis Appointment and the Need for an Ambulance

Medicare and TRICARE reimburse qualifying, medically necessary ambulance transportation to dialysis. The appointment creates a need to reach treatment. The patient’s condition determines the need for an ambulance.

That distinction matters on a recurring route. Dialysis ambulance fraud can turn repeated treatment appointments into repeated claims for unnecessary transportation. A description of the patient that supports one claim can support the next trip’s billing too, even while employees keep seeing a person who can travel another way.

In the Guam Medical Transport plea admissions, the defendants acknowledged knowing that many patients were not bed-confined and had no acute medical condition that otherwise qualified them for ambulance transportation. Their admitted knowledge covered the patient’s condition and the reason the programs would not reimburse the ride.

Medicare’s ambulance coverage rule requires the patient’s condition to justify both the ambulance and the level of service provided. A signed physician certification statement supplies evidence of medical necessity alongside the medical records. The signature alone does not establish it. For the crew or biller, the underlying question remains concrete: what about this patient required this transport?

What Does Bed-Confined Mean for Medicare Dialysis Ambulance Billing?

Medicare’s bed-confinement test describes a patient who cannot get out of bed without assistance, cannot walk and cannot sit in a chair or wheelchair. The patient’s overall condition determines whether an ambulance is needed. Bed confinement is only one part of that assessment.

Employees Raised Billing Concerns and Management Knew

The defendants admitted that other company employees raised concerns about the company’s Medicare and TRICARE billing practices. They knew about those concerns and failed to address them.

The defendants also admitted that they had failed to familiarize themselves with the applicable regulations and guidelines while knowing the company transported patients who did not qualify. We find that combination telling: they knew enough about reimbursement to order walking references removed, while employees’ concerns about the billing went unanswered.

Removing the References to Walking

In their guilty pleas, the defendants admitted directing company employees to remove references to patients’ ability to walk from internal documents because they knew Medicare and TRICARE would not reimburse those patients’ transports. The reason for the edit is the point. Information about the patient was being removed because of its effect on payment.

Walking could disappear from a document. It could not disappear from what an employee had seen.

A Parallel in Falsified Ambulance Run Reports

Falsified ambulance run reports show how control over the patient’s account can move from the crew to the billing office. In a separate civil whistleblower case against Hart to Heart Transportation Services, a former employee brought the case and the government joined it. The government’s complaint alleged that crews were told to leave a room when they found a patient sitting, standing or walking, ask facility staff to put the patient in bed, and then record only the later observation.

The complaint also alleged that management and billing staff could change the crew’s patient care reports themselves:

Those patient care reports allegedly carried a different account of the patient after management or billing intervened. Guam Medical Transport’s defendants admitted directing the removal of walking references from internal documents. The connection is control over which observations survive into the records used to support payment.

The Records Prepared for Investigators

By the Justice Department’s October 2019 plea announcement, five former Guam Medical Transport owners and employees had pleaded guilty to defrauding Medicare and TRICARE in the scheme. An additional former employee pleaded guilty to obstructing justice by falsifying materials the company prepared in response to a Department of Health and Human Services subpoena.

That was a separate guilty plea concerning the response to investigators. It adds another place where an employee could know the difference between the company’s original information and the account it presented outside the business.

What Guam Medical Transport Billed and What the Government Paid

According to court documents described in the Justice Department’s June 2020 account of the criminal case, Guam Medical Transport submitted approximately $32 million in claims to Medicare during the scheme. The defendants admitted that the conspiracy resulted in approximately $10.8 million in improper payments to the company. The document changes and ignored concerns had a financial consequence: public healthcare money paid for ambulance rides patients did not medically need.

The defendants also admitted using proceeds for personal expenses, including vacations, personal income taxes and a residence. They then caused those costs to be falsely categorized as company business expenses, reducing the company’s taxable income and tax liability.

Guam’s Later Review of Repetitive Ambulance Claims

Guam entered Medicare’s expansion of prior authorization for repetitive scheduled non-emergency ambulance transport on February 1, 2022, after the conduct described in the pleas. The Centers for Medicare & Medicaid Services explained in its national expansion notice that prior authorization uses the medical information already required to support payment, earlier in the process. That makes the accuracy of the patient account important before the bill is paid.

What Evidence Does a Whistleblower Need?

For conduct like Guam Medical Transport’s, the useful evidence connects the patient’s condition, the internal document, the billing decision and what management knew. A crew member may know what the patient could do. A billing employee may know the instruction to remove it. Someone who raised concerns may know who heard them and how the company responded.

We work with those different views of the operation to understand how an inaccurate account became a government claim. The detail that seems small inside the company, such as who requested an edit or heard a warning, can explain a decision the finished paperwork hides. A whistleblower case under the False Claims Act can pay 15% to 30% of what the government recovers.
