John provides legal guidance to healthcare sector clients on a broad variety of topics, including Medicare/Medicaid reimbursement issues, corporate compliance, data privacy and cybersecurity concerns, healthcare provider licensure and medical staffing concerns, involuntary commitment laws, and general healthcare regulatory support. He represents a diverse roster of healthcare entities, including for-profit and nonprofit hospitals and health systems, academic medical centers, individual physicians and physician groups, ambulatory surgery centers, ancillary service providers, medical billing companies, skilled nursing and rehabilitation facilities, behavioral health centers and pharmacies.

John advises on Medicaid reimbursement matters before the New Jersey Division of Medical Assistance and Health Services (DMAHS), which administers the state’s Medicaid programs, and handles Medicare reimbursement disputes, both in New Jersey and in numerous other states, before the federal Provider Reimbursement Review Board (PRRB). 

In the area of corporate compliance, John supports clients on matters including the implementation of new, and the assessment and improvement of existing, compliance programs. He assists healthcare clients in navigating compliance audits, internal investigations, and governmental investigations related to compliance issues, which may trigger self-disclosure and repayment processes when non-compliance, including potential violations of the federal Stark Law, Anti-Kickback Statute (AKS), and Civil Monetary Penalties law (CMP) are discovered. He further provides general guidance concerning compliance and regulatory matters under state and federal healthcare laws.   

On issues related to information privacy and cybersecurity at the intersection of healthcare law, John assists providers with issues arising under the Health Insurance Portability and Accountability Act (HIPAA) and the Health Information Technology for Economic and Clinical Health Act (HITECH). This includes the implementation and assessment of privacy and security policies and procedures to ensure the proper protection and utilization of protected health information (PHI) both by healthcare providers and the business associates with which they contract. In addition, he represents healthcare clients in investigating, reporting, and remediating information breaches and the liability such breaches create under various information privacy and security laws.  

John also counsels healthcare providers with professional licensure issues and advises hospitals and health systems regarding their medical staff bylaws and corresponding policies and procedures, as well as assisting with internal investigations of medical staff members and the corresponding disciplinary process. He further provides legal guidance related to New Jersey’s involuntary commitment laws, and provides representation in civil litigation.
