Representative Matters

Daniel Ryan has a diverse commercial litigation practice. Clients appreciate his recognized ability to strategically and aggressively resolve business disputes, particularly in matters tried in federal courts and through arbitration. His technical background includes a unique combination of capabilities in managed care litigation, health care litigation, employee benefits litigation, consumer fraud, bad faith, biometric privacy acts, corporate disputes, IT software implementation disputes, securities fraud, and corporate dissolutions.

Dan's business litigation practice is nationally focused, with cases venued throughout the country. In addition to various arbitration forums, he represents his clients before a wide variety of appellate forums, including the United States Courts of Appeals for the Seventh, Eighth, and Ninth Circuits, the Illinois and Indiana Appellate Courts, the United States District Courts from coast to coast, the EEOC, the Illinois Department of Human Rights, and the Illinois Human Rights Commission. Dan has tried numerous cases, both jury and non-jury. His practice also entails a substantial number of matters involving alternative dispute resolution, mediation, and arbitration.

Dan devotes a significant part of his practice to managed care disputes in counseling health plans and commercial payors in disputes regarding underpayments, denials based on medical necessity, experimental treatments, recoupments, coding audits, and not separately reimbursable line item charge denials. His managed care matters involve both in-network and out-of-network providers, many of which are resolved through arbitrations with the American Arbitration Association (AAA), American Health Law Association (AHLA), and JAMS. He represents employee benefit plans and fiduciaries in court litigation, both ERISA and non-ERISA, including trials and appeals. Dan's employee benefits litigation experience in this area includes the defense of health, life, and disability benefit claims.

Dan is also highly knowledgeable in the area of "special remedies." He has obtained injunctive relief in business disputes involving hospitals, health care plans, limited liability companies, and corporate dissolutions. Dan also concentrates a significant amount of his practice in the areas of non-competition agreements.
