Mayer v. ADCS Clinics: Landmark False Claims Act Whistleblower Ruling

While headlines often chase billion-dollar settlements, the most significant legal battles usually happen in the quiet of a judge’s chambers, far before a single cent is paid. In the world of government fraud and whistleblower law, that battle is currently raging in a Philadelphia federal court.

On February 10, 2026, Judge Chad F. Kenney of the U.S. District Court for the Eastern District of Pennsylvania issued a landmark memorandum in United States ex rel. Jonathan Mayer v. ADCS Clinics, LLC, et al., No. 2:21-cv-05303, U.S. Dist. LEXIS 26795, (E.D.P.A. 2026).

At first glance, it looks like a standard healthcare fraud case involving dermatology billing. But beneath the surface, the defendants launched a legal “nuclear option”: an attempt to declare the whistleblower provisions of the False Claims Act (FCA) unconstitutional. Had they succeeded, the primary tool used by the government to recover billions in stolen taxpayer money would have been effectively dismantled.

The Background: Upcoding in the Exam Room

The case began with Dr. Jonathan Mayer, a dermatologist formerly employed by Advanced Dermatology of Colorado, a subsidiary of ADCS Clinics, LLC. ADCS is one of the largest dermatology networks in the United States, managing hundreds of providers across multiple states.

Dr. Mayer alleged that the network was operating a systematic “upcoding” scheme designed to juice profits at the expense of Medicare and other federal programs. According to the complaint, ADCS leadership allegedly:

• Forced Higher Billing Codes: Directed doctors to stop using lower-level codes for patient visits and instead use more expensive codes, regardless of the complexity of the actual visit.
• Mandated Unnecessary Procedures: Encouraged “Total Body Skin Exams” (TBSE) for patients even when there was no medical reason to perform them.
• Violated the Stark Law: Maintained improper financial relationships with labs and pathologists, creating illegal incentives for internal referrals.

Mayer, No. 2:21-cv-05303, at *3. Dr. Mayer was terminated in March 2020, allegedly just two weeks after he formally objected to these practices. He then filed a qui tam (whistleblower) lawsuit under the False Claims Act. Id.

The Holding: A Direct Challenge to the “Qui Tam”

After years of discovery, ADCS Clinics moved for judgment on the pleadings. Id.  at *4. They didn’t just argue that they were innocent of the fraud; they argued that the entire structure of the False Claims Act’s whistleblower system is unconstitutional.

They claimed that when a private citizen like Dr. Mayer sues on behalf of the United States, it violates Article II of the Constitution, specifically:

1. The Appointments Clause: Because whistleblowers exercise “significant executive power” but are not appointed by the President.
2. The Take Care Clause: Because the President cannot adequately oversee or fire whistleblowers to ensure the laws are “faithfully executed.”

The Holding: Judge Kenney emphatically denied the defendants’ motion. He held that the qui tam provisions of the False Claims Act do not violate the Constitution and that Dr. Mayer could proceed with his case.

The Reasoning: Why Whistleblowers Aren’t “Officers”

Judge Kenney’s reasoning focused on the distinction between a government official and a private litigant.

1. The “Continuing Position” Test

Under the Appointments Clause, someone is only an “Officer of the United States” if they occupy a “continuing position established by law.” Judge Kenney found that a whistleblower (relator) is not an officer because:

• They have no tenure or permanent duration.
• They don’t receive a government salary.
• They don’t have a broad set of duties to the public; they only have an interest in a single, specific lawsuit.

Id. at *7-*9.

2. Significant Authority vs. Private Litigation

The defendants argued that whistleblowers wield the “awesome power of the United States.” Judge Kenney disagreed, noting that relators only have access to the same “tools” as any other private citizen in a civil lawsuit (like subpoenas and depositions). They do not have the uniquely executive powers of the government, such as:

• The power to issue search warrants.
• The power to grant criminal immunity.
• The power to stop the government from intervening and taking over the case.

Id. at *10-*13.

3. History is the Ultimate Tie-Breaker

Perhaps most importantly, the court pointed to the long history of qui tam statutes in America. From the very first Congress—which included many of the Constitution’s Framers—private citizens were authorized to sue for penalties on behalf of the government. This historical “pedigree” makes it highly unlikely the Founders intended to ban the practice. Id. at *16-*17.

Why This Case is a “Big Deal”

If you’re wondering why a dermatology billing case matters to the average person, consider the stakes.

1. The Survival of the FCA: The False Claims Act is the government’s #1 weapon against fraud. Since 1986, it has recovered over $75 billion, with the vast majority of that coming from cases initiated by whistleblowers. If the ADCS challenge had succeeded, the government would lose its “eyes and ears” inside corrupt organizations.
2. A Growing Judicial Conflict: The Mayer case is part of a larger, coordinated effort by corporate defendants to strike down the FCA. While Judge Kenney upheld the law, a judge in Florida recently ruled the opposite way in a different case (Zafirov v. Florida Medical Associates, 751 F. Supp. 3d 1293 (M.D. Fla. 2024)). This creates a “circuit split,” which is the fastest way for a case to reach the U.S. Supreme Court.
3. The Future of Accountability: The outcome of Mayer v. ADCS Clinics will determine whether a doctor, an engineer, or an accountant can still hold a powerful corporation accountable for stealing from the public. It’s a battle over who gets to represent the “interests of the United States”—the Department of Justice alone, or the citizens who witness the fraud firsthand.

Upcoming Mayer v. ADCS Clinics Trial: What to Expect

The Mayer case is now moving toward a potentially explosive trial. While the constitutional challenge was a major hurdle, Dr. Mayer still has to prove that ADCS Clinics actually committed the fraud.

For now, the False Claims Act remains standing in Pennsylvania, but the legal community is watching the docket in No. 2:21-cv-05303 very closely. The next time you see a headline about a massive fraud recovery, remember that it might all have vanished if not for rulings like the one in this case.
