Investigations & Disputes
When facing investigations or litigation, healthcare organizations and their legal counsel can engage us to help strengthen operations and protect assets and reputations. Our integrated team includes seasoned healthcare professionals with high-level credentials in economics, accounting, finance, valuation, complex data analysis, computer forensics and fraud investigations.
How We Help
We have played a significant role in many well-known and substantive healthcare investigations and litigation matters, including mergers and acquisitions, False Claims Act cases, Stark Law and Anti-Kickback Statute investigations, class actions, antitrust and business disputes, and other issues. Our team members testify as expert witnesses at trial and deposition in federal and state proceedings, before administrative bodies, and in bankruptcy and tax court. Clients rely on our evidence-based analyses, including benchmarking, advanced statistical sampling, development of complex industry and company-specific databases, and sophisticated risk assessment techniques.
