Healthcare Disputes
Glenn has extensive experience as an arbitrator in healthcare disputes under both the American Arbitration Association (AAA) and the American Health Law Association (AHLA) arbitration rules. Some representative cases are listed below.
Glenn practiced healthcare law for almost four decades before becoming a full-time neutral. He co-chaired his firm’s healthcare litigation team, which, at the time of his retirement from the firm, included 25 attorneys primarily dedicated to healthcare litigation, as well as several other attorneys who litigated healthcare disputes as part of their practice. His healthcare experience includes provider-payor disputes, False Claims Act cases, government investigations, tort claims, survey and certification issues, and an array of contract disputes.
Glenn is ranked by Chambers USA: America’s Leading Lawyers for Business in its highest tier (“Band 1”) for healthcare law. He was named by Best Lawyers in America as Georgia “Lawyer of the Year” in healthcare law in 2025 and 2015.
Glenn Hendrix is “noted for his handling of a wide range of contentious matters in the healthcare space, including Medicare and Medicaid reimbursement disputes. Interviewees name him as a ‘great attorney.’”

Glenn also has significant experience conducting internal investigations, often at the initiative of public company boards of directors. These tend to involve compliance with the “60-day rule” for refunding overpayments to federal healthcare programs (42 U.S.C. § 1320a-7k(d)). He utilizes deep knowledge of reimbursement principles and the “reverse false claims” provisions in the False Claims Act to make considered judgments regarding the provider’s compliance obligations. He brings an open mind, common sense, and good judgment to the process.
Glenn is a frequent speaker on health law topics—primarily in the areas of healthcare arbitration, reimbursement, compliance, fraud and abuse, and risk management. For some of his presentations, click here.
Glenn is the immediate past chair of the AHLA Dispute Resolution Service Review Board, which rules on petitions to remove arbitrators. He is a member of AHLA and the ABA Health Law Section.
