Health Care


Tracking the multitude of laws that govern the health care field can overwhelm any hospital system or other provider. As a former attorney with the US Department of Health and Human Services, Joseph Willey helps health care providers identify issues of concern and find workable solutions. When problems arise, he’s skilled at litigating a range of claims, including reimbursement disputes. In recent years, he has recouped more than $320 million in additional Medicare reimbursement for hospitals.

Reimbursements are the life blood of most hospital systems and health care providers. Joe’s thorough understanding of the intricacies of the Medicare and Medicaid systems allows him to take aggressive yet grounded positions in disputes. He has convinced courts to dismiss enormous government claims against his clients and has settled other matters for a small fraction of the amount the government sought. His clients rely on him for guidance related to fraud and abuse matters, saying, “Joseph Willey is commended for his ‘truly encyclopedic knowledge of Medicaid and Medicare law'” (Chambers USA).

Joe’s decades of experience allows him to provide clients with clear roadmaps through the complex regulatory landscape. He advises on federal anti-kickback and physician self-referral laws and represents providers in investigations and litigation under the False Claims Act. He also represents providers in federal and state government audits and before administrative tribunals, including the Provider Reimbursement Review Board.

Clients also turn to him to help devise business strategies for their health care operations.
