Healthcare Litigation & Dispute Resolution

From reimbursement regulations to provider manuals, we know the issues affecting our healthcare clients’ businesses. We don’t scramble to get up to speed on the fly and on the client’s dime.


Today’s regulatory and reimbursement environment exposes healthcare providers and life sciences companies to complex disputes with payors, the government, intermediaries, vendors, other providers, and sometimes patients. Our healthcare litigators distinguish themselves with an unusual combination of healthcare expertise and litigation prowess to protect our healthcare clients’ interests in whatever dispute they may face. We bring our insider knowledge of the healthcare industry to the matters we handle in the courtroom, arbitrations, and complex administrative investigations and appeals.

We handle all aspects of healthcare litigation for our provider and industry clients, from resolving reimbursement disputes with payors to moving for injunctions against government recoupments and licensure revocations to defending national whistleblower suits and False Claims Act investigations. For providers and companies facing steep fines and civil monetary penalties (CMPs), we are there from the independent dispute resolution (IDR) level, through the complex administrative appeal levels, and on to the courts if necessary. For clients addressing a data security incident and related claims or investigations, we provide support in navigating the multifaceted and time-sensitive response process. We also have a team dedicated to assisting clients with regulatory changes and navigating and responding to the No Surprises Act.

And, of course, sometimes disputes arise between providers, providers and their vendors, and providers and their employees.  Whether enforcing contractual obligations, recovering disputed escrow funds, or enforcing non-compete agreements, we are there for our clients.

Our in-depth industry knowledge is complemented by clinical and provider-side experience. Our team includes former clinicians (physical and respiratory therapists), former Assistant United States Attorneys, former OIG counsel, certified compliance consultants, and registered nurses for medical record analysis and insights.
