Healthcare Fraud Investigation Defense Lawyer in Chicago

A healthcare fraud investigation usually begins long before anyone knocks on your door. It starts with billing data. Federal analysts flag a spike in claims, an unusual pattern of codes, or a provider billing more hours than the staff could possibly work. By the time a subpoena arrives, agents are interviewing patients, or Medicare payments suddenly stop, the government may have been building its case for months.

Enforcement is at historic levels. When the Department of Justice announced its 2026 National Health Care Fraud Takedown in June, it charged 455 people, 90 of them doctors and other licensed medical professionals, in schemes tied to more than $6.5 billion in allegedly false claims (U.S. Department of Justice). The Northern District of Illinois was among the federal districts involved.

How Healthcare Fraud Investigations Begin

Most modern health care fraud cases start with the data. Federal regulations list the kinds of information that can support a “credible allegation of fraud” (42 CFR § 405.370):

Fraud hotline tips that are verified by further evidence
Claims data mining
Patterns identified through provider audits, civil false claims cases, and law enforcement investigations

The Justice Department has been open about its reliance on cutting-edge analytics. In the 2026 Takedown, DOJ described an Illinois Medicaid case involving an alleged $67 million behavioral health billing scheme. Analysts found claims for 500 or more hours of counseling per day and patients billed for services while hospitalized elsewhere. Prosecutors opened the investigation within five days of the financial review, and the defendant was arrested less than seven months later (U.S. Department of Justice).

Investigations also begin with people. Whistleblowers can file lawsuits under the False Claims Act, and they filed a record 1,297 of those lawsuits in fiscal year 2025 (U.S. Department of Justice). Those whistleblowers are often former employees, billing staff, business partners, or competitors. Patient complaints, insurance company audits, and tips from insiders round out the picture.

Who Investigates Healthcare Fraud in Chicago

Healthcare fraud cases in the Chicago area typically involve several agencies working together:

The FBI calls itself the lead agency for investigating health care fraud, covering both government programs and private insurers (FBI).
HHS-OIG are special agents from the U.S. Department of Health and Human Services Office of Inspector General focus on Medicare and Medicaid fraud, waste, and abuse.
The Illinois Attorney General’s Medicaid Fraud Control Unit investigates and prosecutes Medicaid provider fraud and patient abuse or neglect (Illinois Attorney General).
The DEA gets involved when a case involves prescribing or dispensing controlled substances.
Other agencies can join too, including IRS Criminal Investigation, the Department of Labor’s inspector general, and the Office of Personnel Management’s inspector general, depending on which health plans were billed.

Federal cases are prosecuted by the U.S. Attorney’s Office for the Northern District of Illinois. They are often brought alongside the DOJ’s Midwest Health Care Fraud Strike Force, which works with prosecutors in Chicago and Detroit on schemes involving telemedicine, laboratories, pharmacies, therapy services, and prescription drugs (U.S. Department of Justice). A Medicare Fraud Strike Force has operated in Chicago since 2011 (U.S. Attorney’s Office, N.D. Ill.).

Signs You May Be Under Investigation

Healthcare providers often see warning signs before any criminal charges are filed:

A subpoena for medical records, billing data, or bank accounts
Contact from agents, such as special agents interviewing your patients, employees, or referral sources
A civil investigative demand or letter from the U.S. Attorney’s Office about potential False Claims Act liability
A payment suspension from Medicare or Illinois Medicaid
A search warrant executed at your office or clinic
A target letter from federal prosecutors

You should be paying close attention if you receive a payment suspension. When Illinois Medicaid decides a credible fraud allegation is being investigated, federal rules generally require it to freeze a provider’s payments, often with no warning beforehand and unless the agency finds a specific reason to hold off (42 CFR § 455.23). In the 2026 Takedown alone, CMS suspended 1,079 providers and revoked billing privileges for 1,403 more.

Common Allegations in Healthcare Fraud Cases

Investigators look for recognizable health care fraud schemes, including:

Phantom billing – Meaning claims for services or supplies that were never provided
Upcoding, – Meaning billing for a more expensive service than the one performed
Medically unnecessary services – Including tests, therapy, or procedures billed without clinical need
Illegal kickbacks – Meaning payments or benefits in exchange for patient referrals
Falsified medical records – Including false diagnoses used to support claims
Durable medical equipment, laboratory, genetic testing, and telemedicine billing schemes
Hospice, home health, behavioral health, and wound care billing
Diversion of controlled substances through prescriptions or pharmacies

An allegation is not proof. Many cases involve complex billing practices, gray areas in coding rules, and legitimate clinical judgment that looks unusual in a spreadsheet. Separating actual billing errors from fraud committed with intent is where the defense begins.

The Criminal, Civil, and Administrative Stakes

A healthcare fraud investigation can lead to three separate kinds of consequences, sometimes all at once.

Criminal Charges

A conviction under 18 U.S.C. § 1347 can bring as much as 10 years in federal prison. That ceiling jumps to 20 years when the fraud causes serious bodily injury, and to life when someone dies as a result. You do not have to know the health care fraud law exists to break it. The government must still prove the person acted knowingly and willfully to defraud a health care benefit program.

The Anti-Kickback Statute is a separate felony carrying up to 10 years in prison and fines up to $100,000 (Federal Register). Prosecutors frequently add conspiracy, wire fraud, money laundering, and false statement charges, along with forfeiture of fraud proceeds.

Civil Liability

The False Claims Act allows the government to recover three times its losses, plus a penalty for each false claim. Those per-claim penalties currently run from about $14,300 to about $28,600 because the 2026 inflation adjustment was canceled (Federal Register). DOJ reported record False Claims Act recoveries of more than $6.8 billion in fiscal year 2025, with over $5.7 billion from health care matters (U.S. Department of Justice).

Administrative Action

HHS-OIG must exclude anyone convicted of certain health care offenses from federal health care programs for a minimum of five years (HHS-OIG). For a physician or clinic owner, exclusion can end a career even if the prison sentence is short. State licensing boards may also take action.

What Sentencing Looks Like

In fiscal year 2025, 68% of people sentenced for federal health care fraud received prison time, and the average sentence was 21 months (U.S. Sentencing Commission). The most important part of that statistic is that 91% had little or no prior criminal history. The median loss was nearly $1.3 million, and 33% received a sentencing increase for abusing a position of trust or using a special skill, which often applies to licensed professionals. These are severe consequences for people who never expected to see the inside of a courtroom.

Why Early Intervention Matters

The period before charges are filed is often the most valuable time to have a defense attorney. During that window, counsel can:

Find out where you stand – Learn whether you are considered a witness, subject, or target.
Open a line of communication – Talk with prosecutors and agents before they lock in their theory.
Present your side – Share medical records, billing guidance, and clinical explanations the government may not have seen.
Coordinate the parallel tracks – Handle civil, criminal, and administrative proceedings together so a statement in one does not damage you in another.
Pursue a better resolution – In appropriate cases, work toward a civil or administrative outcome instead of criminal charges.

If you learn you may be under investigation, protect yourself:

Do not talk to agents without a lawyer – A false or inaccurate statement to a federal agent is a separate felony carrying up to five years (Congressional Research Service). Your right to remain silent also applies here.
Do not change, backdate, or add to medical records – Altering documents after the fact can create obstruction charges far worse than the original billing issue.
Do not contact patients, employees, or referral sources about what they may tell investigators.
Do not repay money or make a self-disclosure without advice – How and when repayment happens can affect both civil and criminal exposure.

How We Defend Healthcare Fraud Investigations and Charges

Healthcare fraud cases are document-heavy and data-driven. Our defense starts by understanding the government’s numbers better than the government does. Depending on the facts, the defense may focus on:

Intent and good faith – Medicare and Medicaid billing rules are complex and change often. Reliance on billing companies, coding guidance, or compliance advice can show there was no intent to defraud.
Medical necessity – Clinical decisions made by licensed professionals are not crimes simply because an auditor disagrees. Independent clinical review can support the care that was provided.
The data itself – Statistical outliers are not proof of fraud. Sampling methods, extrapolated loss figures, and flawed billing data analysis can be challenged.
Kickback allegations – Many financial relationships in health care are legal, including arrangements that fit statutory safe harbors or bona fide employment.
Individual role – Billing staff, office managers, and employed clinicians often had little control over how a practice operated. The evidence may not support holding them responsible for decisions made by others.
Loss and sentencing – The loss amount drives the federal sentencing guidelines. Challenging the government’s calculation can reduce exposure significantly.

Healthcare Fraud Investigation Questions We Hear Often

Is Every Healthcare Fraud Investigation Criminal?

No. Many investigations are civil or administrative, focused on repayment, False Claims Act liability, or payment suspension. But civil and criminal cases can run in parallel, and information gathered in one can be shared with the other. That is why having criminal defense counsel involved from the start matters.

Can I Be Charged If I Did Not Know the Billing Rules?

The health care fraud statute does not require knowledge of the statute itself. The government must still prove you acted knowingly and willfully with intent to defraud. Honest mistakes and good-faith reliance on billing guidance are not crimes, and building that record early is critical.

Does a Payment Suspension Mean I Will Be Charged?

Not necessarily. A suspension means an agency believes there is a credible allegation of fraud that warrants investigation. It is a serious warning sign, and how you respond can shape what happens next.
