Kathryn’s practice is at the intersection of three industry groups: health care payors, property and casualty (P&C) insurers, and government contractors. For three decades she has represented health care insurers and affiliates in their work with federal health care programs (including Medicare, Medicaid, the Federal Employees Health Benefits Program, Veterans Health Administration, and TRICARE). From government contractors of administrative services to managed care organizations with underwriting risks, all navigate complex regulations and government oversight. Kathryn has devoted a significant part of her practice to representing Medicare Administrative Contractors (MACs) in procurement, regulatory compliance, and litigation matters, including both defending False Claims qui tam suits and teaming with the U.S. Department of Justice in its prosecution of Medicare fraud by providers and suppliers. This unique practice mix has positioned her as a recognized thought leader on Medicare Secondary Payer (MSP) issues for P&C insurers, specifically their “Section 111” reporting and related reimbursement obligations to the Medicare Program.  

Kathryn is leader and founder of the firm’s specialty Section 111 Insurer Reporting and MSP Reimbursement practice begun in 2009. Read more here.
