Why Is My Business or Practice Being Targeted by the…

…Federal Bureau of Investigation (FBI)?

The Federal Bureau of Investigation (FBI) investigates a broad range of alleged criminal conduct. From computer and internet crimes to public corruption, if there is reason to suspect that you may have committed (or may currently be involved a conspiracy to commit) a federal crime, there is a decent chance that the FBI will be involved in your investigation.

…Office of Inspector General (OIG)?

The Office of Inspector General (OIG) is the law enforcement division of the Department of Health and Human Services (DHHS). It is responsible for: “protect[ing] the integrity of [DHHS] programs as well as the health and welfare of program beneficiaries,” which primarily involves targeting health care providers and other industry players in Medicare and Medicaid fraud investigations.

…Internal Revenue Service (IRS)?

The Internal Revenue Service (IRS) collects your taxes, and it will try to put you in federal prison if you don’t pay. Most people don’t realize it, but the IRS has a criminal enforcement division that aggressively pursues individuals and businesses suspected of underreporting and underpaying their federal income tax obligations. In addition to targeting individuals and businesses directly, the IRS also routinely gets involved in large-scale federal fraud investigations involving the FBI, OIG, and other agencies.

…Drug Enforcement Administration (DEA)?

The Drug Enforcement Administration (DEA) targets health care providers and other entities suspected of engaging in prescription drug diversion and other violations of the federal Controlled Substances Act. Criminal DEA investigations can have extreme consequences, and health care providers (and other individuals and businesses) targeted in these investigations must be prepared to fully commit themselves to their defense.

FAQs: Defending against Federal Criminal Charges in California

Q: Why am I being accused of 'health care fraud'?

Federal agencies, including the OIG and DEA, are targeting physicians, pharmacists, and other providers for health care fraud in California – and they are doing so aggressively. “Health care fraud” is a blanket term that covers various types of civil and criminal offenses, including violations of the False Claims Act, the Anti-Kickback Statute, and the Stark Law. Billing and coding violations are common triggers for federal health care fraud investigations, although numerous other alleged forms of impropriety can lead to federal action as well.

Q: When is prescription drug diversion considered a federal crime?

Putting prescription drugs in the hands of patients (or non-patients) who don’t need them is a federal offense. The federal laws governing the prescription and administration of controlled-substance medications are extremely strict, and physicians, pharmacists, and other providers can face federal charges for practices including:

  • Prescribing medically-unnecessary medications

  • Selling prescriptions

  • Providing prescription medications to non-patients or without an in-person exam

  • Over-filling or under-filling prescriptions

  • Forging prescriptions

Q: What penalties could I be facing as the result of a federal criminal investigation?

The two primary types of penalties under federal law are fines and imprisonment. Most federal criminal statutes include provisions for substantial fines (typically in the tens or hundreds of thousands of dollars) and substantial terms of federal incarceration (years or decades behind bars). In federal investigations targeting health care providers, other direct and indirect consequences can include:

  • Recoupments and denial of pending payments

  • Pre-payment review

  • Program exclusion (Medicare, Medicaid, and Tricare ineligibility)

  • Loss of licensure

Q: What should I do if I am aware of improper billing practices or other unlawful activity?

If you are aware of improper billing practices or other unlawful activity, you need to be extremely careful. You need to avoid engaging in conduct that could lead to additional charges or penalties. However, you also need to avoid tipping off federal agents and prosecutors that you are aware of a situation that needs to be remedied. Our California federal criminal defense lawyers can guide you through what you need to do, step-by-step.

Q: If I am still under investigation, should I hire a defense lawyer?

Yes, absolutely. Defending yourself during the investigative process is the best way to mitigate your risk of conviction, penalties, and long-term reputational harm. Oftentimes, federal investigations will be well-intentioned but severely misguided, and unveiling the government’s flawed assumptions and methodologies can save you from substantial unnecessary costs, stress, and business interruptions.
