Kate Bowles draws upon her in-depth litigation experience and background as a Registered Nurse to bring deep industry knowledge and expertise when representing healthcare providers. Focusing on investigation and enforcement of Medicare/Medi-Cal Fraud and Abuse, Stark Law, Anti-Kickback Statute, business and reimbursement litigation, and white-collar defense, Kate uses her first-hand understanding of the challenges faced by hospitals, surgery centers and individual providers to achieve exceptional results.

Diversity of Provider Clients
Kate’s experience encompasses all aspects of healthcare, including traditional healthcare systems and emerging groups in the outpatient sector, such as surgery centers, telehealth providers and substance use treatment facilities. Kate handles trial, mediation and arbitration of disputes with a variety of payors from commercial to employer to Government. Representing a diversity of providers allows Kate to effectively evaluate the motivations of various players within the healthcare industry and take advantage of emerging trends.

Focus on Prevention
Kate also brings to her practice a focus on compliance and prevention of disputes and regularly works with attorneys in Nelson Hardiman’s transactional, regulatory and finance departments to provide a full-service approach to healthcare provider clients. Payors are becoming increasingly focused on whether healthcare providers have a robust and functioning compliance program – and if not – ensuring that one is put in place following litigation through Corporate Integrity Agreements (CIAs). In this era, it is ever-more important for healthcare providers take a “big picture” approach to preventing litigation.

Life Outside the Firm
The perseverance and resolve in Kate’s healthcare law practice is reflected in her time volunteering to teach students in healthcare and legal programs about key “law and policy” drivers that have a real, practical effect on their anticipated practice area. Kate is an avid traveler, runner, yogi and enjoys being outdoors and raising her two daughters.
