A former Sunnyvale resident has pleaded guilty to his role in a massive healthcare fraud operation that targeted Medicare Advantage programs for millions of dollars. Sevindik Huseynov, a forty eight year old Azerbaijan national who served as the CEO of Vonyes Inc., appeared in court on Tuesday to admit to three counts of health care fraud. Authorities say Huseynov led a durable medical equipment company that became the center of an aggressive scheme to defraud the government through fraudulent billing practices.
According to the U.S. Department of Justice, Huseynov helped orchestrate the submission of thousands of fake claims between January and June of 2025. These claims were filed using the information of unsuspecting beneficiaries and sought a staggering 137 million dollars in reimbursements. Investigators found that the requested funds were for medical equipment that was never actually delivered to patients, was not medically necessary, and had never been authorized by any legitimate healthcare provider.
As part of his plea, Huseynov admitted that he personally received reimbursement checks totaling 2.8 million dollars. He deposited these funds into various bank accounts established under Vonyes before wiring the majority of the money to offshore accounts located in Hong Kong. The elaborate financial trail eventually led federal investigators back to him, resulting in an indictment by a federal grand jury in September 2025.
Huseynov currently remains in federal custody as he awaits his official sentencing scheduled for February 2, 2027. If convicted on all counts, he faces a maximum statutory penalty of ten years in prison along with a fine of up to 250,000 dollars. This case highlights ongoing efforts by federal authorities to crack down on sophisticated schemes designed to drain resources from public health insurance programs.
