How a San Diego Workers' Compensation Fraud Ring Stole Millions
A comprehensive investigation into a San Diego-based fraud ring revealed a complex scheme that exploited the California workers' compensation system, resulting in over $200 million in fraudulent claims. This case underscores the critical need for vigilance and robust enforcement to protect the integrity of workers' compensation programs and the efforts of insurance companies to combat insurance fraud.
The Fraudulent Scheme
The operation centered around a network of patient recruiters, medical professionals, and attorneys who manipulated the workers' compensation system for personal gain. Key figures included:
Carlos Arguello: Operated several patient recruitment entities, including Centro Legal, which used advertising to attract injured workers seeking compensation benefits.
Fermin Iglesias: Collaborated with Arguello to establish companies that directed patients to corrupt medical providers and legal representatives.
Injured workers, primarily seasonal and migrant laborers, were lured by advertisements and directed to specific doctors and lawyers. These professionals prioritized profit over patient care, subjecting individuals to unnecessary medical procedures and tests to inflate billing. For instance, a patient with a minor knee injury might undergo unwarranted urine tests, DNA tests, sleep studies, and multiple MRIs on unrelated body parts. The conspirators enforced quotas, requiring doctors to prescribe a minimum number of medical goods and services per patient. Failure to meet these quotas resulted in the cessation of patient referrals. Financial transactions, including kickbacks, were often conducted covertly, with cash exchanged in public places to avoid detection.
Investigation and Legal Proceedings

The FBI, in collaboration with the San Diego District Attorney’s Office and the California Department of Insurance, led an extensive investigation into the fraud ring. The inquiry revealed that the network had defrauded the California workers' compensation system and private insurers of more than $200 million. As a result of the investigation:
Carlos Arguello: Sentenced to four years in prison.
Fermin Iglesias: Sentenced to five years in prison.
In total, 32 individuals and companies pleaded guilty, and five were convicted by a jury, receiving prison sentences of up to 10 years. Additionally, over $1.2 billion in suspect billings were frozen.
These convictions included multiple counts of insurance fraud related to the false insurance claims submitted by the fraudulent network. This case has drawn the attention of private investigators, including those from Salazar Investigations, who have long been involved in uncovering fraudulent claims. Salazar Investigations is widely known for offering a range of clients dedicated to tackling cases involving insurance fraud and domestic investigations.
Impact and Legislative Response
The fraudulent activities not only caused substantial financial losses but also compromised patient care, with individuals subjected to unnecessary and sometimes painful procedures. In response to this and similar cases, California enacted legislation in 2017 mandating the suspension of bills submitted by medical providers charged with fraud or abuse within the workers' compensation system.
This case highlights the importance of continued vigilance, inter-agency cooperation, and legislative action to combat workers' compensation fraud and protect both the system and its beneficiaries. The efforts of Salazar Investigations have been instrumental in uncovering these types of fraud, especially within high-stakes sectors involving insurance.
