Experienced Federal Law Defense Attorneys for Chicago Healthcare Professionals

If you are a doctor, pharmacist, nurse, or business owner in the medical field, you’ve worked hard to get where you are. Years of diligent study have earned you respect in your community, and a career for which you can be proud.

But when the federal government targets you for a criminal investigation pertaining to alleged healthcare fraud, those achievements can come crashing down around you.

Healthcare providers in Chicago know this all too well. Chicago is one of just nine cities in the United States where the federal government operates a designated Medicare Fraud Strike Force. The government chose Chicago because there are so many Medicare beneficiaries living in the Windy City metro, and because the city is one of the largest in the country.

The Strike Force is part of a larger initiative known as the Healthcare Fraud and Prevention and Enforcement Action Team, or HEAT, a joint effort by the U.S. Department of Justice (DOJ), Office of the Inspector General (OIG), and Department of Health and Human Services (HHS).

The HEAT strike force closely collaborates with numerous state, local, and federal agencies, which means it can take rapid action against clinics or individual owners and providers who violate healthcare laws. And because HEAT switched its emphasis from enforcement to prevention in 2010, that rapid action can affect you long before the government has actually proved you’ve done something wrong.

For instance, if you practice in a small medical clinic in Illinois, and you make a small billing error involving a Medicare patient (accidentally coding for the wrong services, for example), the Chicago Medicare Fraud Strike Force could refer the activity to the Centers for Medicare & Medicaid Services (CMS) as a “credible suspicion” of fraudulent billing. CMS would then have authority to immediately cease all payments to your practice, which could have a potentially debilitating impact on your ability to do business. The strike force would then likely move in with an investigation or a raid, further impacting your business and casting a pall over your professional reputation in the community.

Medicare fraud isn’t the only allegation you have to worry about either. The healthcare industry is heavily regulated, so simple clerical errors can trigger a whole host of legal problems, including alleged violations of the:

Because Chicago is home to one of the principal HEAT Strike Force offices, practitioners in the Windy City are under heightened scrutiny. While the federal Strike Forces are technically national watchdogs, in reality, most of their takedown efforts happen in the cities where they’re headquartered.

If you are currently under audit, investigation, or suspicion for violating healthcare laws in the Chicago area, please take immediate action to protect your legal interests. The government takes these cases seriously and approaches them aggressively. You should too. There’s a lot on the line.

The Federal Government Will Try to Prosecute Small Errors

Medicare Fraud Strike Forces have already arrested and charged more than 2,000 people around the country in connection with alleged healthcare fraud, many of them in Chicago and Illinois.

While most of the arrests are individual in nature, the Strike Forces coordinate them in highly publicized “takedown sweeps,” which the agencies then tout as major federal achievements in taxpayer protection.

In reality, however, many of these arrests spring from overblown accusations. Often, they boil down to innocent mistakes or minor clerical errors. That’s why you must take every audit, every investigation, and every conversation with a federal agent extremely seriously.

The government will use your records, filings, invoices, statements, and any other available evidence against you.

Examples of Healthcare Fraud Takedowns in Chicago

  • In 2011, the HEAT Strike Force expanded to Chicago and promptly charged 14 defendants in the greater Chicago area with healthcare fraud. The arrests were part of a larger sweep involving 111 individuals across the country, totaling some $225 million in alleged fraud.
  • In 2013, the Chicago Medicare Fraud Strike Force simultaneously announced the arrest of seven people in five separate, unrelated “healthcare fraud schemes” worth millions of dollars combined. The defendants included two doctors and three co-owners of a local health clinic.
  • A nationwide Strike Force sweep in 2016 saw 301 people charged, including two high-profile arrests of Chicago-area doctors: a physician in Buffalo Grove and another practitioner in Skokie.

The federal agents in Chicago are relentless. These are only a few examples of the federal government’s continuous prevention and enforcement efforts. They demonstrate the need to pay careful attention to your office’s billing and filing patterns.

Still, even those who are careful can end up on the wrong side of a federal investigation.

While healthcare fraud is unquestionably a problem, the government’s eagerness to “crack down” on crime frequently leads to overreach. Innocent healthcare professionals end up targeted unfairly.

What Triggers a Healthcare Fraud Audit or Investigation?

Data collection and analysis is a key part of federal investigators’ work. Often, an audit or investigation begins because of a perceived irregularity in data connected with your hospital, clinic, pharmacy, or practice. Tips from patients or community members might also raise a red flag. Some audits or inspections are routine (but even regularly scheduled federal prodding can lead to misunderstandings and overblown complications).

The most common mistakes that healthcare companies and their employees make involve simple billing errors.

For example, the government frequently targets Chicago clinics for:

  • Phantom billing (i.e., billing for services that were not performed)
  • Double billing for treatment services or medical equipment
  • Inflating charges
  • Upcoding for treatment, disorders, services, or equipment
  • Certifying for medically unnecessary supplies (e.g., DME) or services (e.g., hospice care)
  • Billing for equipment that was never ordered
  • Billing for services that Medicare does not cover as covered services
  • Inefficient billing
  • Bending the Medicare rules
  • Overusing certain services or equipment
  • Providing (or accepting) kickbacks or bribes

Who Are the Most Common Defendants in Healthcare Criminal Cases?

Many of the individuals investigated for alleged healthcare fraud are people who never imagined they would face criminal suspicion, or potential federal felony charges.

Nevertheless, the government is as aggressive against people in the medical field as it is against drug dealers in the streets. Common defendants in Chicago healthcare criminal cases include:


  • Business owners / co-owners
  • Dentists
  • Directors
  • Doctors
  • Executives
  • Nurses
  • Nursing home employees
  • Pharmacists
  • Physician’s Assistants
  • Registered Nurses
  • Surgeons
  • Other healthcare service providers


  • Cancer treatment centers
  • Clinics
  • DNA Centers
  • Healthcare marketing companies
  • HMOs
  • Hospitals
  • Laboratories
  • Medical equipment vendors
  • Nursing homes
  • Pharmacies
  • Registered care facilities
