Ensuring our clients are prepared and proactive when responding to government investigations

At Quarles, we understand the health care industry is steeped in regulations that often create obstacles for even the most well-intentioned organizations and individuals. As the regulatory landscape changes, we help you stay proactive and prepared so you are ready to comply with new mandates and avoid regulatory missteps. We also analyze the risks and benefits to voluntarily disclosing any potentially false claims made to the government. In the event that you are facing potential prosecution or an enforcement action, we will help you develop a strategic response, including assessing risks and mitigation actions to any inquiries or subpoenas. We also help you carry out internal investigations to identify risks before they arise. Our attorneys have deep understanding of the health care and pharmaceutical industries as well as experience with state attorneys general offices, the DEA, DOJ, FDA and OIG/HHS, among other agencies.
