Ken McArthur’s practice is focused on health care litigation, counseling, and consulting on a national level. He has 26 plus years of experience working in the health care sector and has assisted thousands of health care sector participants throughout the U.S.— including professionals, businesses, associations, and government entities — in a broad spectrum of legal and government relations matters ranging from those involving strategic advice to those involving highly-complex litigation.

Ken has represented health care clients in a variety of civil litigation matters in federal and state courts around the country.  Most of these matters have been complex litigation (including multi-district litigation and class actions) involving allegations of anticompetitive and fraudulent conduct in the U.S. pharmaceutical industry.

In addition to handling litigation matters, Ken counsels health care businesses on compliance with federal and state laws governing business arrangements within the highly-regulated U.S. health care sector. He also represents both health care professionals and businesses in government and private-party audits, internal and external investigations, disciplinary/regulatory enforcement matters, contractual negotiations, and payment disputes.

Ken has also served in numerous litigation, regulatory, and government relations matters as a consulting expert on the subjects of pharmacy law, pharmaceutical care, pharmacy benefit management, prescription drug benefit plans, prescription drug pricing practices, and the roles of pharmacists and pharmacies in the U.S. health care system. Having taught pharmacy law at the graduate school level and served clients from every segment of the U.S. pharmaceutical supply chain, Ken has an uncommonly deep knowledge of pharmacy law and the U.S. pharmaceutical industry.     

Previous clients include drug repackagers, drug wholesalers, durable medical equipment (DME) providers, government entities (state and federal), group purchasing organizations (GPOs), health plan sponsors, health plans, health systems, home health care providers, hospice providers, hospitals, law firms representing health care sector participants, long-term care (LTC) facilities, managed care organizations (MCOs), medical practices, medical transportation providers, nurse practitioners, pharmaceutical manufacturers, pharmacies (compounding, institutional, mail-order, retail, and specialty), pharmacists, pharmacy benefit managers (PBMs), pharmacy services administration organizations (PSAOs), physical therapists, physician assistants, physicians, professional/trade associations, psychologists, psychology practices, and surgical assistants.
