Kathryn’s practice is at the intersection of three industry groups: health care, insurance, and government contracts. 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, and TRICARE). From government contractors of administrative services to insurers and managed care organizations with underwriting risks, all must navigate complex regulations and government oversight. Kathryn has devoted a significant part of her practice to representing these clients in procurement matters, litigation, and regulatory disputes arising under Medicare law, the Federal Employees Health Benefits Act, and the Affordable Care Act (ACA); defending Medicare contractors in complex False Claims Act investigations and qui tam suits; and negotiating complex pharmacy benefit management (PBM) contracts. 

Kathryn is co-chair of the firm’s Health Care Group and also chair and founder of the firm’s specialty practice for property and casualty (P&C) insurers with Medicare obligations. Her unique practice mix has positioned her as a recognized thought leader on Medicare secondary payer issues for these insurers, including how to meet their “Section 111” reporting and reimbursement obligations.
