Health care providers and health care companies targeted in government investigations and civil litigation, especially those companies facing allegations under the False Claims Act (“FCA”), seek Jonah Retzinger for his counsel and comprehensive analysis of complex legal problems. 

Recognizing that health industry participants operate in a dynamic sector, where the “rules of the game” are often a morass, Jonah conducts in-depth regulatory reviews, implements creative litigation management plans, and works with tailored teams of attorneys and subject-matter experts to advance client positions. Whether he is engaging a government agency, preparing a dispositive motion in federal court in a qui tam matter, or navigating revenue cycle management considerations, Jonah is praised by clients for his commitment to the craft, his resourcefulness, and his methodological approach to novel and multidimensional issues.

In addition to his FCA and litigation practice, Jonah advises physician practice management organizations, medical groups, health systems, hospitals, and other providers and suppliers on understanding and adapting to their changing legal environment.

A thought leader in the space, Jonah’s recent efforts have focused on the federal No Surprises Act, which contains balance billing and surprise billing prohibitions and created a negotiation and independent dispute resolution process for provider-payor rate disputes, as well as recent regulations issued by the Department of Health and Human Services (“HHS”), which limit the issuance and use of sub-regulatory guidance documents. 

Before joining Epstein Becker Green, Jonah clerked for the HHS Office of Counsel to the Inspector General.
