District of Arizona Announces Charges Involving Over $1.2 Billion in False or Fraudulent Claims as Part of National Health Care Fraud Takedown

PHOENIX, Ariz. – Today, United States Attorney Timothy Courchaine announced criminal charges against four defendants in connection with alleged schemes to defraud Medicare, Medicaid, and other federal health care programs of over $1.2 billion. The charges filed in federal court are part of the Department of Justice’s 2026 National Health Care Fraud Takedown. 

“The billions of dollars of fraud highlighted in today’s announcement should shock and anger every American,” said U.S. Attorney Timothy Courchaine. “We must protect our valuable federal health care programs from exploitation by criminals. The message from the success of this takedown is clear – the United States government will protect taxpayer dollars and will prosecute those who seek to defraud our country.”

The charges announced today by U.S. Attorney Timothy Courchaine are part of a strategically coordinated, nationwide law enforcement action that resulted in charges against 455 defendants, including 90 doctors and other licensed medical professionals, for their alleged participation in health care fraud and opioid abuse schemes involving over $6.5 billion in false claims and significant patient harm, including death. Today’s Takedown represents a new era in federal, state, and international cooperation to combat health care fraud: cases in 56 federal districts and 45 U.S. states and territories, with 50 state Medicaid Fraud Control Units participating, the most in Department history. In addition, unprecedented international cooperation over the two-week Takedown resulted in the apprehension and return to the United States of the following health care fraudsters: one defendant in Kyrenia in connection with an over $3.7 billion scheme; two defendants in Estonia in connection with a previously charged $10.6 billion scheme; and, in the Philippines, one of FBI’s Most Wanted Fraudsters in connection with a previously-charged $1.2 billion telemedicine fraud scheme. The Takedown involves the cutting-edge use of data analytics to target the worst actors; the seizure of over $182 million in cash, luxury vehicles, jewelry, and other assets; and full-spectrum accountability for all criminal actors from doctor’s offices to corporate boardrooms.   

Today’s coordinated enforcement action involves a whole-of-government approach, including:

• Actions by the Centers for Medicare and Medicaid Services (CMS) to suspend 1,079 providers and revoke billing privileges for 1,403 providers.
• 48 Civil Monetary Payment settlements amounting to over $73 million, over 1,400 provider exclusions, and 25 actions by the U.S. Department of Health and Human Services, Office of Inspector General (“HHS-OIG”) under the Civil Monetary Penalties Law seeking more than $10 billion in payments to the Medicare Trust Fund from payments that CMS caught and suspended before the funds were paid to the fraudulent providers.
• Civil charges against 13 defendants for $14.8 million in health care fraud schemes, as well as civil settlements with 31 defendants totaling $23 million.
• 928 administrative cases by the Drug Enforcement Administration (DEA) seeking the revocation of authority to handle and/or prescribe controlled substances since October 1, 2025.

The following individuals were charged in the District of Arizona: 

• Susie Kamien, 55, of West Chester, Illinois, was charged by information with conspiracy to commit health care fraud in connection with submitting over $918 million in false and fraudulent claims to Medicare for amniotic wound allografts. As alleged in the information, Kamien was a medical biller who submitted claims to Medicare for allografts that were medically unreasonable and unnecessary, and procured through illegal kickbacks and bribes. The case is being prosecuted by Trial Attorneys Shane Butland and William Hochul III of the National Rapid Response Strike Force and Assistant U.S. Attorney Matthew Williams of the District of Arizona.
• Jimmy Muyumbu, 38, formerly of Glendale, Arizona, was charged by indictment with conspiracy to commit health care fraud and wire fraud, health care fraud, conspiracy to launder money, and money laundering, in connection with an alleged scheme involving a substance abuse treatment clinic in Arizona that billed Arizona Medicaid over $44 million. As alleged in the indictment, Muyumbu owned and operated an outpatient treatment center called Motherland Counseling LLC (“Motherland”) in Phoenix, Arizona, which was purportedly in the business of providing addiction treatment services for vulnerable patients suffering from alcohol and drug addiction. Muyumbu enrolled Motherland as a provider with Arizona’s Medicaid agency, the Arizona Health Care Cost Containment System (“AHCCCS”). Muyumbu sought out patients enrolled in AHCCCS’s  American Indian Health Program, a fee-for-service program for Native American AHCCCS members. Muyumbu and his co-conspirators exploited these patients by submitting approximately $44,920,644 in false and fraudulent claims to AHCCCS for services that were not provided, were not provided as billed, were so substandard that they failed to serve a treatment purpose, were not used as part of or integrated into any treatment plan, were tainted by illegal kickbacks and bribes, and, in some cases, were medically unnecessary. AHCCCS paid approximately $36,678,016 based on these fraudulent claims. Muyumbu then laundered the fraudulent proceeds by purchasing real estate in the greater Phoenix area. The government seized approximately $104,463 in proceeds from Muyumbu’s alleged fraud scheme. The case is being prosecuted by Trial Attorney Sarah Edwards and Assistant Chief Jim Hayes of the National Rapid Response Strike Force and Assistant U.S. Attorney Matthew Williams of the District of Arizona. Assistant U.S. Attorney Joseph Bozdech is handling the forfeiture aspects of the case.
• Sandra Peters, 45, of Saint Johns, Florida, was charged by information with conspiracy to commit health care fraud in connection with over $10 million in false and fraudulent claims to Medicare for amniotic wound allografts. As alleged in the information, Peters was a sales representative who ordered and recommended allografts that were medically unreasonable and unnecessary, and procured through illegal kickbacks and bribes. The case is being prosecuted by Trial Attorneys Shane Butland and William Hochul III of the National Rapid Response Strike Force and Assistant U.S. Attorney Matthew Williams of the District of Arizona.
• Brian Rowan, 47, of Las Vegas, Nevada, was charged by indictment with conspiracy to commit health care and wire fraud, health care fraud, conspiracy to defraud the United States and to pay health care kickbacks, paying health care kickbacks, and transactional money laundering, in connection with a $1.2 billion wound allograft scheme. As alleged in the Indictment, Rowan, the Vice President of Sales for a company that sold expensive amniotic wound allografts, caused hundreds of millions of dollars in illegal kickbacks, bribes, and rebates to be paid to sales representatives and medical providers throughout the country to unlawfully induce purchases of the company’s allografts. Rowan and his co-conspirators concealed these kickbacks and bribes by issuing sham sales invoices to providers in amounts that exceeded the providers’ actual cost of the allografts and directing providers to use the amounts reflected on those invoices for Medicare reimbursement, thereby inflating Medicare’s reimbursements and concealing the providers’ undisclosed and unreported profits. Rowan and his co-conspirators further concealed the kickbacks and bribes by using pass-through bank accounts associated with a shell company to funnel the illegal kickbacks and bribes to providers in exchange for purchasing the company’s allografts. Induced by these unlawful financial incentives, sales representatives and providers targeted elderly patients, many of whom were terminally ill in hospice care, and caused medically unreasonable and unnecessary allografts to be applied to these vulnerable patients. Between December 2021 and June 2024, Rowan and his co-conspirators caused the submission of $1.2 billion in false and fraudulent claims to Medicare, TRICARE, CHAMPVA, and commercial insurers, of which approximately $614 million was paid. Rowan personally made over $24 million, which he used to purchase multi-million-dollar houses, million-dollar life insurance policies, luxury vehicles, and luxury watches. The case is being prosecuted by Trial Attorneys Shane Butland and William Hochul III of the National Rapid Response Strike Force, and Assistant U.S. Attorney Matthew Williams of the District of Arizona.

The District of Arizona, in particular, worked with the Department’s Health Care Fraud Unit of the Fraud Division and the following law enforcement agencies to investigate and prosecute the cases filed during the Takedown: the Federal Bureau of Investigation, the U.S. Department of Health and Human Services Office of Inspector General, the U.S. Department of Veteran’s Affairs Office of Inspector General, and the U.S. Department of War Defense Criminal Investigative Service.

On April 7, the Department of Justice announced the creation of the National Fraud Enforcement Division (“Fraud Division”). The Fraud Division is laser-focused on investigating and prosecuting those who commit fraud against the American people. The Department’s work to combat fraud supports President Trump’s Task Force to Eliminate Fraud, a whole-of-government effort chaired by Vice President J.D. Vance to eliminate fraud, waste, and abuse within Federal benefit programs.

An indictment, information, or complaint is merely an allegation. All defendants are presumed innocent until proven guilty beyond a reasonable doubt in a court of law.
