David Farber advises leading life sciences companies and healthcare providers on their most complex, high-stakes challenges—where litigation risk, regulatory uncertainty, and government policy converge—and where the path to a successful outcome requires an integrated, strategic approach.
Clients turn to him to solve problems that cannot be addressed through litigation, compliance, or advocacy alone. He is frequently engaged when companies face existential or enterprise-level risks, including reimbursement disputes that threaten core revenue streams, enforcement actions with significant financial and reputational exposure, and regulatory frameworks that limit market access or create operational uncertainty. His work is focused on delivering outcomes that protect and enhance the client’s business, not simply resolving discrete legal issues.
In litigation, he represents clients in matters that define how healthcare products and services are paid for and regulated. He is particularly sought out for disputes involving reimbursement systems, statutory interpretation, and federal healthcare programs—cases in which a favorable result can reshape financial outcomes at scale. In a recent jury trial, he not only successfully defending against a $2.4 billion claim, but prevailed on a counterclaim that brought hundreds of millions of dollars in client value.
On the regulatory front, David helps clients navigate the complexities of coverage, coding, reimbursement, and compliance under federal healthcare programs. Clients rely on him to convert highly technical regulatory regimes into clear, actionable strategies to access markets and secure payment. He is widely recognized for his command of Medicare and related reimbursement systems. David regularly works on the most cutting edge novel treatments, including cell and gene therapies, xenotransplantation, and brain-computer interface treatments.
David will help clients achieve results through policy and legislative solutions when legal or regulatory pathways are insufficient. He has drafted and worked with Congress to enact legislation that address structural challenges—whether by clarifying statutory ambiguities, securing legislative changes, or shaping how agencies implement and enforce the law. He regularly builds and directs coalitions, aligns stakeholders, and engaging directly with decision-makers to drive his client’s goals.
He is frequently called upon in situations where the stakes extend beyond a single matter to broader industry implications—such as when reimbursement methodologies are contested, enforcement trends shift, or new policy initiatives affect entire sectors. In these settings, he helps clients not only respond to immediate challenges, but also influence the rules that will govern future operations.
