Attorney Dennis Sapien-Pangindian draws on his experience at HHS-OIG, the largest Inspector General’s office in the U.S. government, to guide health care providers, health plans, and life sciences clients who are confronted with information blocking issues, fraud and abuse issues, grant fraud issues (e.g., NIH, HRSA, ACF), regulatory compliance, health care business disputes, and state and federal government investigations.

Dennis has substantial experience managing internal investigations concerning alleged violations of the Food, Drug, and Cosmetic Act; the Anti-Kickback Statute (AKS); and the False Claims Act (FCA). Dennis also has experience with the information blocking law and regulations that were promulgated under the 21st Century Cures Act. Clients value his strategic thinking, sharp litigation skills, and deep knowledge of government health care programs. Dennis helps clients respond to U.S. Department of Justice (DOJ) and Medicaid Fraud Control Unit (MFCU) subpoenas and demands, develops investigation work plans, and designs and conducts compliance reviews tailored to clients’ needs, including patient support programs and pharmaceutical sponsored genetic testing programs.

Before joining Epstein Becker Green, Dennis was a health care and life sciences attorney at an international law firm. He previously served as an Associate Counsel in the Administrative and Civil Remedies Branch of HHS-OIG. As Associate Counsel, Dennis represented HHS in various administrative and civil fraud enforcement actions, including FCA, AKS, Stark Law, and Civil Monetary Penalties Law matters. He also negotiated and monitored Corporate Integrity Agreements with several entities on behalf of HHS-OIG and advised HHS on policy issues related to implementing the HHS-OIG’s information blocking authorities under the 21st Century Cures Act.
