Areas of Practice

Katie O’Neill advises a broad range of healthcare industry participants, including physician groups, healthcare investors, non-profit hospital systems and their affiliates, and insurance companies. She seeks to understand each client’s business and compliance issues and then find practical and efficient legal solutions to solve problems and reduce risk. Katie’s practice centers on commercial contracting, mergers and acquisitions, corporate governance, and legal/operational issues. She regularly structures and negotiates arrangements involving physician and mid-level employment matters, administrative/management services, professional services, ancillary services (e.g., laboratory services, imaging modalities, fertility and cancer treatments, DME, etc.), and healthcare purchasing/supply chain matters.

Katie’s transactional practice is supported by her experience with federal and state law governing healthcare operations (e.g., corporate practice of medicine, fraud and abuse, licensure, commercial and governmental payor reimbursement, and peer review/fair hearings, including related state and federal reporting requirements). As a former registered nurse, Katie’s clinical experience informs her practical understanding of the healthcare industry and its benefits and challenges.
