David Greenberg represents health care providers nationwide in complex reimbursement and managed care disputes with commercial insurers and government health care payors, including Medicare Advantage plans, Medicaid managed care plans and TRICARE.

With more than 20 years of experience, he handles complex managed care contracting and payment disputes, payor audits and investigations, arbitration and litigation. His practice centers on helping providers address reimbursement challenges, from negotiating managed care agreements to pursuing disputed payments and defending against recoupment claims.  

David advises clients across the health care industry, from hospital systems and physician practice management companies to laboratories, dialysis providers, home health and hospice companies, behavioral health providers, pharmacies and pharmaceutical companies. That breadth of experience informs his work on reimbursement, regulatory, and compliance matters involving coding and coverage, fraud and abuse, the Anti-Kickback Statute, the No Surprises Act, and participation in Medicare, Medicaid and other government health care programs. He also conducts internal investigations and represents clients in federal and state audits, enforcement actions and False Claims Act investigations and litigation.

A frequent author on health care compliance and reimbursement, he is also the lead editor of the Practising Law Institute treatise Health Care Litigation and Risk Management Answer Book and is a contributing author to the Bloomberg Law treatise: Health Care Fraud and Abuse: Practical Perspectives. Earlier in his career, David handled antitrust and health care litigation involving insurers, pharmaceutical companies and pharmacy benefit managers.
