U.S. Attorney’s Office for the Middle District of Florida Charges Defendants as Part of National Health Care Fraud Takedown

Today, United States Attorney Gregory W. Kehoe announces criminal charges against numerous individuals in connection with alleged schemes to defraud Medicare. In addition, one civil settlement was announced. Many of the charges are part of the Department of Justice's 2026 National Health Care Fraud Takedown and stem from schemes to defraud Medicare.

"Millions of Americans depend on critical services provided by our nation's federal healthcare programs," said U.S. Attorney Gregory W. Kehoe. "Companies or individuals who exploit these systems through fraud and deception for their personal gain compromise the efficacy of those services and commit theft from taxpayers. We will continue to leverage the resources of our law enforcement partners to ensure that these programs remain sound and effective in the future."

This week, the USAO-MDFL participated in 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. The Takedown represents a new era in federal, state, and international cooperation to combat health care fraud: charges in 56 federal districts and involving 45 U.S. states and territories, the most in Department history. The Takedown involved the cutting-edge use of data analytics to target the worst actors; seize over $182 million in cash, houses, luxury vehicles, jewelry, and other assets; and provide full spectrum accountability for all criminal actors from doctor's offices to corporate boardrooms.

The following individuals were charged in the Middle District of Florida:

Leigh Tesar (44, Sarasota), Walter Presha, Jr. (51, Ellenton), and Koby Evans (31, Apollo Beach) were charged by indictment for their roles in a more than $118 million wound care fraud scheme. Tesar, Presha, and Evans were charged with conspiracy to defraud the United States and to pay and receive health care kickbacks. Tesar was charged with health care fraud and payment of health care kickbacks. Presha and Evans were also charged with receipt of health care kickbacks. As alleged in the indictment, Tesar, Presha, and Evans targeted Medicare patients so that Tesar, a nurse practitioner, could bill Medicare for unnecessary and expensive wound allografts and so that Presha and Evans, both nurses, could be paid kickbacks for referring patients to Tesar. In certain instances, Tesar caused Medicare to be billed for expensive allografts that were never applied to patients, were applied to infected wounds, and were applied to wounds that would not heal because the patient was terminally ill. During a period of 18 months, Medicare was billed more than $118 million for skin grafts and wound care services that were medically unnecessary, ineligible for reimbursement, not performed, and procured through kickbacks. Medicare paid approximately $61 million based on these false and fraudulent claims. The government has seized approximately $11.8 million in assets in this matter. The case is being prosecuted by Trial Attorneys Chris Wenger of the National Rapid Response Strike Force and Owen Dunn of the Florida Strike Force. The forfeiture is being handled by Assistant United States Attorney James A. Muench.

Leo Corrigan (56, Tampa) was charged by information with conspiracy to defraud the United States, to purchase, sell, and distribute, and arrange for the purchase, sale, and distribution of Medicare beneficiary identification numbers, and to solicit and receive health care kickbacks in connection with two schemes to fraudulently bill Medicare for over $7.5 million and to receive approximately $1.7 million in illegal kickbacks and bribes. As alleged in the information, Corrigan conspired with others to purchase Medicare beneficiary identification numbers and used those numbers to bill Medicare for over-the-counter COVID-19 tests to be shipped to those whose Medicare beneficiary identification number had been purchased, regardless of whether the Medicare beneficiary had requested the tests. Further, Corrigan owned and controlled a corporation that he used to provide Medicare beneficiary information to certain laboratories that could then use the information to bill Medicare for genetic testing in exchange for payment. This case is being prosecuted by Assistant United States Attorney Tiffany E. Fields.

Konstantin Braverman (40, Lake Worth) was charged by indictment with conspiracy to commit health care fraud and conspiracy to solicit and receive kickbacks in connection with a scheme to submit fraudulent claims to Medicare for COVID-19 tests. From April 4, 2022, until the declared end of the COVID-19 public health emergency on May 11, 2023, Medicare covered and paid for these tests at no cost to the beneficiary but only if the beneficiary requested the tests. As alleged in the indictment, Braverman and co-conspirators introduced "marketers" to medical service providers and the "marketers" agreed to sell the providers lists of Medicare beneficiaries and their identifying information. The providers shipped COVID-19 tests to the identified beneficiaries, none of whom had requested the tests, and billed Medicare for the tests. The providers then paid the "marketers" a set dollar amount per beneficiary, but the providers paid this amount only if a claim submitted on behalf of a beneficiary was reimbursed by Medicare. The "marketers" paid Braverman a share of the proceeds obtained from the providers. The conspirators caused the submission of approximately 152,000 fraudulent claims to Medicare for the period of January 2023 through November 2023, which resulted in reimbursements totaling approximately $14,405,700. Braverman received a total of approximately $1,509,426 in proceeds as a result of his involvement in the offense. The case is being prosecuted by Assistant U.S. Attorney Arnold B. Corsmeier of the U.S. Attorney's Office for the Middle District of Florida. Assistant U.S. Attorney Clint Locke is handling the forfeiture.

"This defendant allegedly exploited a program designed to serve the public during a national health emergency, fraudulently obtaining more than $1.5 million in proceeds," said FBI Jacksonville Special Agent in Charge Jason Carley. "Health care fraud is not a victimless crime. It steals taxpayer dollars, undermines trust in critical public programs and diverts resources from those who need it most. The FBI will continue to work with our partners to pursue those who use deception and fraud to line their own pockets at the public's expense."

Lawrence Waldman, of Miami, has entered into a civil settlement to pay $5 million to resolve a False Claims Act case in connection with a health care fraud kickback scheme involving medically unnecessary genetic and respiratory diagnostic testing services. Waldman separately pleaded guilty to criminal charges stemming from his role in the scheme. His sentencing hearing is scheduled for July 28, 2026. As alleged, Waldman was a former sales representative of ASAP Labs and shared in its profits. Waldman paid kickbacks from ASAP Labs to certain physicians in return for agreeing to sign requisition forms for medically unnecessary laboratory tests that were submitted by ASAP Labs in violation of the Federal Anti-Kickback statute and that were used to support false claims for Medicare, Medicaid, and TRICARE reimbursement. The civil case is being handled by Assistant U.S. Attorney Kelley Howard-Allen. The criminal case is being prosecuted by Assistant United States Attorney Tiffany E. Fields, and the forfeiture is being handled by Assistant United States Attorney James A. Muench.

Rustam Abdaev, (38, Tampa) a Russian citizen living in Tampa, was charged by information with one count of conspiracy to commit money laundering for his role in defrauding Medicare and Medicaid by submitting false and fraudulent claims for durable medical equipment ("DME"). Abdaev has entered a guilty plea and is pending sentencing. According to court records, from at least December 2024 through June 2025, Abdaev and co-conspirators used the company "Sunny and Recovery Inc." to submit false and fraudulent claims to Medicare Part C and Florida Medicaid for DME, including back, knee, and wrist braces. Medicare Part C and Medicaid were billed more than $19 million and paid approximately $941,000 for claims submitted between December 2024 and May 2025. Abdaev wired substantial portions of the proceeds to financial institutions outside the United States and used additional funds for personal benefit and to pay co-conspirators. The conspirators used stolen beneficiary information and physician provider numbers to submit DME claims that were not prescribed, not medically necessary, and not actually provided. The case is being prosecuted by Assistant United States Attorney Tiffany E. Fields, and the forfeiture is being handled by Assistant United States Attorney James A. Muench.

Henry Garcia (59, Bradenton) was charged by indictment with one count of conspiracy to offer and pay kickbacks and bribes and nine counts of offering and paying kickbacks and bribes. According to court records, in 2020 and 2021, Garcia ran multiple medical equipment companies, including New Level 3 and On-Point Medical Alliance, that supplied knee and back braces to Medicare beneficiaries. Garcia worked with two co-conspirators: one in Florida who funneled him pre completed doctors' orders, and another in Canada who ran call centers targeting Medicare beneficiaries to generate those orders. These call centers contacted seniors across the country and used telemedicine companies to obtain physician signatures on brace orders, even when the equipment was not medically needed. Garcia's companies obtained the necessary provider identification numbers and submitted claims to Medicare Advantage plans as if the braces were legitimately ordered and required. Garcia paid kickbacks for each brace order that led to reimbursement. The scheme relied on call centers, sham telehealth encounters, and kickbacks to generate and submit claims that were not actually eligible for reimbursement. The case is being prosecuted by Assistant United States Attorney Tiffany E. Fields, and the forfeiture is being handled by Assistant United States Attorney Blain Goff.

Marc Vincent Pazienza (56, Pasco County), a licensed Florida attorney, was charged by indictment with two counts of wire fraud and two counts of falsification of records in a federal investigation for his role in using his position and authority as an attorney to defraud clients, including by creating shell corporations to hide clients' criminally derived proceeds and then stealing those funds. According to court documents, from June 2023 through at least March 2025, Pazienza orchestrated a scheme to steal money from two of his clients by falsely promising to safeguard their money, funds which were fraudulently obtained through defrauding Medicare. Instead of safeguarding the funds, Pazienza used the money, an amount over $300,000, for his personal benefit, including cash withdrawals, transfers to other accounts he controlled, and purchases of furniture, jewelry, and other items. Pazienza also provided false and fraudulent documents in response to a federal grand jury subpoena relating to a health care fraud investigation. The case is being prosecuted by Assistant United States Attorney Tiffany Fields, and the forfeiture of his car, jewelry, and other property is being handled by Assistant United States Attorney James A. Muench.

Laurent Cassagnol (Orange County) and Heriberto L. Rivera (Lake County) were charged by information with conspiracy to pay and receive kickbacks. According to court documents, Rivera was the Chief Executive Officer of Family Integrative Medicine of Orlando, LLC ("FIMO") and paid kickbacks to Cassagnol, a Department of Veterans Affairs (VA) employee, in exchange for Cassagnol sending VA patients to FIMO. Rivera allegedly paid kickbacks to Cassagnol based on the number of VA patients he was able to successfully steer to FIMO. FIMO then billed the VA for services it provided to those VA patients. Rivera paid Cassagnol approximately $175,172 in kickbacks, which resulted in approximately $14,080,969 in claims submitted by FIMO to the VA that were procured through the payment of kickbacks. The VA paid FIMO approximately $11,948,349 on those claims. This case is being prosecuted by Trial Attorney Angela Benoit of the Criminal Division's Fraud Section. The forfeiture is being handled by Assistant United States Attorney Nicole Andrejko.

"Today's enforcement action reflects our firm commitment to protecting federal health care programs and the individuals who depend on them," said Special Agent in Charge Isaac M. Bledsoe of the Department of Health and Human Services Office of Inspector General (HHS-OIG). "Those who exploit patients or jeopardize the integrity of our programs for personal gain will be held accountable. Working alongside our law enforcement partners, HHS-OIG will continue to pursue those who seek to defraud federal health care programs and ensure that they face justice."

"These cases highlight the sickening exploitation of our nation's healthcare system and the cold, callous efforts of those putting profit over patient care. These cases also emphasize the FBI's collective resolve to work with our law enforcement partners to identify the fraud, dismantle the schemes, and ensure justice is served," said FBI Tampa Special Agent in Charge Rodney E. Crawford.

"The days of fraudulent healthcare schemes depriving veterans of essential services and benefits, while siphoning funds from taxpayers, are over," said Cheryl L. Mason, Inspector General of the Department of Veterans Affairs. "Thanks to the relentless dedication of the VA OIG's special agents, healthcare inspectors, and auditors, we are actively identifying these offenders and ensuring they face justice. Our unwavering commitment is to protect veterans and safeguard the critical resources meant for their care."

Descriptions of the nationwide cases involved in this week's enforcement action are available on the Department's website here.

The Middle District of Florida 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: U.S. Department of Health and Human Services - Office of Inspector General, the Federal Bureau of Investigation (Tampa and Jacksonville), the U.S. Department of Veterans Affairs - Office of Inspector General, the Defense Criminal Investigative Service - Office of Inspector General, and the Internal Revenue Service Criminal Investigation.

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.
