Clinical Laboratory


For clinical, molecular, and anatomic pathology laboratories across the country, Hooper, Lundy & Bookman provides comprehensive representation focused on facilitating their critical work. We recognize the unique place labs have in the continuum of care and the distinct regulatory, operational, and payment issues they face. Our counsel minimizes compliance risks while our advocacy protects and advances our clients’ interests in reimbursement matters and across the full spectrum of government audits, investigations, enforcement actions, and other litigation.

While clinical laboratories continue to develop novel approaches and increasingly tailored and accurate diagnostic and molecular tests, the legal and business environments in which they operate are also evolving. Managed care, value-based, and other evolving payment arrangements present opportunities and potential risks. At the same time, government scrutiny and the costs and disruptions that can follow are ever-present concerns. HLB works with independent clinical laboratories, physician’s office laboratories (POL), and hospital-operated labs on every day-to-day and long-range issue that intersects with the law.   

Our experience serving clinical laboratories extends back decades, including representing the American Clinical Laboratory Association and the California Clinical Laboratory Association in many high-profile matters. HLB attorneys have played instrumental roles in some of the industry’s most impactful cases, including establishing favorable state and federal court precedent on Medicare payment and coverage issues, alleged fraud and abuse, and other matters. We are recognized throughout the health care industry for our reimbursement practice and compliance capabilities, while a deep bench of litigators, transactional attorneys, and government relations and health care policy professionals complete the full suite of services we provide to clinical laboratories.
