Clients throughout the health care industry and professions rely on our analysis, strategizing, advice, negotiation, and – where necessary – litigation of Medicare and Medicaid reimbursement matters. This can typically involve:

  • Asserting or resisting claims, audits, disallowances, recoupments, and administrative proceedings (including appeals before the HHS Provider Reimbursement Review Board) as well as in State and Federal court
  • Opposing burden­some or improper State regu­latory pro­vi­sions or other unauthorized administrative action
  • Conducting or supervising internal investigations of provider billing practices to determine compliance with applicable requirements, including "overpayment" self-disclosure requirements under the so‑called "60 day" rule
  • Giving informed counsel on innovative reimbursement methodologies including bundled payment programs, ACOs, and other health care initiatives, based on our close monitoring of legal reforms and reimbursement changes that are driving clinical integration initiatives across the country
  • Third-party payor coverage issues
  • Complex or unusual issues as to Medicare and Medicaid managed care, Disproportionate Share Hospitals, Upper Payment Limits, and others
  • Billing dis­putes on a wide variety of legal and factual grounds
  • Defending against or negotiating settlements of False Claims Act (FCA) claims and qui tam litigations
Reimbursement advice and dispute resolution built on experience and longstanding relationships

Our decades of experience in the health care world, combined with strong working relationships with the state and federal Medicaid and Medicare agencies, often allows us to resolve reimbursement issues before they become disputes. We can often obtain clarification on issues of concern that may not be clear on the face of published regulations and guidance.

We believe there is an essential connection between health care FCA litigation and a command of state and federal health care fraud and abuse and reimbursement laws – laws that one appellate court has described as "almost unintelligible to the uninitiated." Our deep Medicare and Medicaid experience explains why major providers have retained Katten to handle their threatened or pending Medicare- and Medicaid-related FCA matters. Our core health care team includes former Assistant US Attorneys with many years of health care litigation experience. And our FCA matters have involved diverse allegations such as duplicate billing, billing for medically unnecessary services, billing for services by unlicensed providers, and violations of the Stark Act and anti-kickback statute. We have also handled FCA allegations involving highly technical issues such as provider billing for physician services in teaching hospitals, school-based health care services, early intervention services, and personal care services in violation of applicable requirements.

In addition, we regularly assist clients with facility licensing and Form 855 preparation. Our attorneys help new providers enroll in the Medicare and Medicaid programs and existing providers complete change of information filings in accordance with CMS requirements. We also work with health system, private equity, and national ancillary care providers to address facility licensing and Medicare/Medicaid enrollment issues in connection with mergers, acquisitions, joint ventures, and other change-of-ownership situations.
