Our Services

Attorneys in the Health Care Litigation practice work closely with the firm's transactional health care attorneys and others to provide a full range of health care litigation, investigative, regulatory and transactional services.

We represent clients in all types of health care-related litigation involving hospitals, provider groups, members of national health and dental benefits associations, provider networks, pharmaceutical suppliers, health data analytics firms, and others involved in the delivery of health care and related services. We have extensive experience defending against qui tam and False Claims Act cases. We handle litigation relating to the purchase and sale of hospitals and other health care assets, including regulatory actions and matters relating to health care information privacy, health care facility expansion and construction projects, the revocation of charitable property tax exemptions, reimbursement rates, the termination of participation agreements, payment for emergency and out-of-network services, and referrals to in and out-of-network surgery centers. Working in conjunction with our health care transactional and regulatory colleagues, we handle antitrust claims, including claims arising from collaboration between health care providers and the integration of various health care services, as well as Racketeer Influenced and Corrupt Organizations Act (RICO) claims.

Katten attorneys also have extensive experience with litigation involving physician compensation agreements, anti-kickback and Stark cases, physician employment actions, and ERISA matters.

Our pharmaceutical work includes pay-for-delay and related antitrust cases, matters relating to the publication of clinical, reimbursement and marketing information about pharmaceutical products, pharmaceutical products liability and actions based on failure to warn, and misfiled prescriptions. Our litigators work closely with our patent lawyers litigating various aspects of pharmaceutical patent challenges, primarily in the generic market.

By combining cutting-edge litigation practices with deep experience in health care, Katten's Health Care Litigation team helps clients achieve business-savvy, cost-effective and sustainable results.

  • Counsel to clients in False Claims Act cases involving allegations of duplicate billing, billing for medically unnecessary services, billing for services by unlicensed providers, violations of the Stark Act and anti-kickback statute, and billing for physician services in teaching hospitals, school-based health care services, early intervention services and personal care services in violation of applicable requirements.

Katten successfully obtained dismissal by the federal district court and ultimately achieved an extremely favorable settlement of all claims against our client.
  • Provision of advice to a hospital management firm in settlement of allegations that it breached the False Claims Act by aiding the inappropriate admissions of patients for hospital services. Katten's client did not admit any wrongdoing and is one of several defendants in New York federal litigation dating back to 2002.
Class Action
  • Defense of a major teaching hospital against a class action suit alleging violations of various statutes in connection with the hospital's billing and collection practices. The suit alleged liability of approximately $20 million. By limiting the scope of the suit through discovery, statutes of limitations and class certification arguments, and the resulting restrictive court rulings, Katten achieved a highly successful settlement of the litigation.
  • Representation of a large municipal health system in a suit filed against the federal Medicare agency alleging an illegal and arbitrary cap on reimbursement cost apportionment.
  • Representation of clients in disputes relating to the publication of clinical, reimbursement and marketing information about pharmaceutical products.

Katten settled the dispute and achieved a result which paved the way for the wellness provider to continue providing the services and receiving reimbursements from the insurer.
  • Successful representation of a wellness provider in a dispute with a major national insurer regarding the right to reimbursement for procedures performed in connection with risk and ASO coverage. Katten achieved a result which paved the way for the wellness provider to continue serving clients and receiving reimbursement from the insurer.
Patient Safety Organization
  • Counsel to national prescription company in its successful appeal in the Illinois Appellate Court against an attempt by the State of Illinois to access confidential information that had been reported to the company's component PSO. In a case of first impression, the trial court dismissed the state's lawsuit, upholding the patient safety organization protections promulgated under PSQIA. In the first appellate court ruling in the country, the court affirmed the trial court's dismissal.
  • Author of amicus briefs filed on behalf of 30 PSOs and health care trade associations before the Kentucky Court of Appeals and the Supreme Court of Kentucky regarding the protection of patient safety work product in a medical malpractice action. Following a split decision of the Kentucky Supreme Court which allowed the trial court's order compelling disclosure to stand, Katten is participating in an amicus brief to be filed with the US Supreme Court.
  • Successful defense of Walgreens against a subpoena issued by the State of Illinois seeking the production of incident reports that had been submitted to a component PSO created by Walgreens pursuant to the PSQIA. When Walgreens refused to produce the reports, Katten served as PSO consultant to litigation counsel and authored an amicus brief filed on behalf of 20 PSOs and health care trade associations supporting Walgreens. The decision dismissing the State's lawsuit against Walgreens was affirmed on appeal, and this was the first state appellate court case in the country to interpret and apply the provisions of the PSQIA which render qualified information non-discoverable and non-admissible in state and federal court proceedings.

Katten obtained an order from the trial court dissolving a temporary restraining order, thus permitting the hospital to revoke the provider's privileges, and successfully defended an emergency appeal filed on the eve of the termination and the submission of a report to the National Practitioner Data Bank.
  • Representation of a hospital, its CEO and hospital employees in a defamation and breach of contract lawsuit filed by a radiation oncologist whose exclusive contract was not renewed. The defendants' motion to dismiss was granted and affirmed on appeal, based in part on Katten's argument that the hospital's response to a third party's inquiry about the quality of plaintiff's services was a protected peer review communication and therefore not subject to discovery or admissibility into evidence.
  • Representation of one of the world's largest pharmaceutical companies in a pay-for-delay case.
  • Representation of clients in connection with claims alleging anticompetitive collaboration among health care providers in violation of the antitrust laws.
  • Counsel to a hospital, department chair and senior management in a state antitrust lawsuit filed by three retinal surgeons whose request for medical staff membership and clinical privileges was denied based on the hospital's position that there was no demonstrated need for these specialists. The suit was dismissed based on the "rule of non-review" as well as the plaintiffs' failure to demonstrate injury to competition in the relevant geographic and product markets.

  • Defense of clients in RICO and other claims arising in connection with the lease of health care provider networks.
