Angelica De Mesa represents insurers in qui tam actions for insurance fraud and unfair business practices against healthcare providers, attorneys, sham law firms and clinics, management services organizations, and their conspirators. She litigates fraud schemes involving the presentation of fraudulent, false, or misleading claims to private payors in violation of California Penal Code sections 549, 550, and 551. This includes taking legal action against illegal business practices such as up-coding, unbundling, employment of runners/cappers/steerers to procure clients or patients, kickbacks, illegal fee-splitting, and lay-person ownership of a professional corporation. Her goal is to reduce fraud against insurers for the benefit of their policyholders and the public overall.

Before focusing on qui tam actions under California Insurance Frauds Prevention Act, Angelica successfully represented victims of elder and dependent adult abuse against skilled nursing homes, residential care facilities, adult day care centers, and hospitals. She was also a litigation fellow for the AARP Foundation and worked on cases involving age discrimination and privacy rights.
