About Our Areas of Practice

1. Healthcare Law

A significant portion of our practice is devoted to representing physicians, pharmacists, hospitals, clinics, toxicology laboratories, medical device companies, and other healthcare providers in federal legal matters. This includes: (i) healthcare law compliance; (ii) healthcare fraud audits and investigations; and (iii) administrative, civil, and criminal healthcare fraud matters.

Healthcare Law Compliance

With notable experience on both sides of healthcare fraud investigations and prosecutions, we offer comprehensive compliance program development and training for providers in Kentucky and nationwide. From structuring compensation arrangements to avoid Stark Law and Anti-Kickback Statute implications to maintaining strict adherence to the Medicare, Medicaid, Tricare, and other government benefit program billing regulations, we help providers avoid the types of mistakes that lead to federal investigations.

3. Business Litigation

Disputes with competitors, suppliers, customers, patients, and former employees can be hugely disruptive, and they can quickly get out of hand if not managed appropriately.

Answers to FAQs: Facing Federal Investigations and Court Proceedings in Kentucky

Q: Which federal agencies have oversight of healthcare providers in Kentucky?


Numerous federal law enforcement agencies are involved in the government’s fight against healthcare fraud. In addition, several agencies have established task forces (including some joint task forces involving multiple agencies) targeting specific aspects of healthcare fraud and abuse. These authorities include:

  • Centers for Medicare and Medicaid Services (CMS)
  • Department of Defense (DOD)
  • Department of Health and Human Services Office of Inspector General (OIG)
  • Department of Justice (DOJ)
  • Department of Labor (DOL)
  • Drug Enforcement Administration (DEA)
  • Federal Bureau of Investigation (FBI)
  • Medicare Fraud Strike Force
  • Opioid Fraud and Abuse Detection Unit

Q: Could I lose my license as a result of a federal investigation or malpractice lawsuit?


Indirectly, yes. If you or your practice is targeted in a federal healthcare fraud investigation or if you are sued for malpractice, this could lead to disciplinary action by the Kentucky Board of Medical Licensure. License suspension or revocation is among the numerous collateral consequences of federal litigation. It is yet another reason to take your case extremely seriously.

Q: What else do I need to know if I am under investigation or facing charges for healthcare fraud?


As the target of a federal healthcare fraud investigation or prosecution, there is a lot you need to know. There are steps you need to take, mistakes you need to avoid, and difficult decisions you will need to make at each stage of the process. For more information, we encourage you to download our free guide: 5 Things You Must Know if You have been Charged with Healthcare Fraud.

We offer a number of other free resources for healthcare providers facing federal legal issues as well.

Q: If I have been arrested on federal charges, do I need to be prepared to go to trial?


Not necessarily. While going to the federal district court is certainly an option (and it may be your best option under certain circumstances), many federal cases are resolved through plea deal negotiations prior to trial. At Oberheiden, P.C., we have even had success getting clients’ charges dismissed following their indictments. The details of your case matter tremendously. And during your free initial consultation, we will begin gathering the information we need to assess the potential outcomes of your case.
