Overview

Patrick C. Harrigan is a partner in the Insurance and Health Care Fraud Litigation and White Collar, Investigations and Compliance groups. He concentrates his practice on conducting complex investigations involving health care fraud, primarily representing large insurers and counseling them on strategies to detect and minimize fraud exposure. He has successfully litigated on behalf of private payers in federal courts to recover losses from fraud, and has also successfully defended health care providers in civil and administrative actions.

Patrick has also handled sensitive internal investigations on behalf of health care providers, substance abuse clinics, hospitals, and medical device companies and counsels them on compliance and self-reporting issues.

Patrick has an active pro bono practice. He serves as the outside general counsel for Reclaim13, a nonprofit which operates a safe house for victims of child sex trafficking. While at Katten, he investigated a wrongful homicide conviction and identified the true perpetrator, leading to the exoneration of an individual who spent 17 years in prison. He also obtained asylum for a Guinean refugee in a contested trial in a case profiled by the US Senate Judiciary Committee, and Deferred Action for Childhood Arrivals relief for a 16-year-old from Egypt.

While in law school, Patrick served as articles editor of the Wisconsin Law Review and as a member of the Moot Court Board, where he was the recipient of the Mathys Memorial Award for excellence in appellate advocacy. He also served as a judicial intern to Chief Justice Shirley S. Abrahamson of the Wisconsin Supreme Court.
