In a high-stakes legal challenge that could fundamentally reshape the financial architecture of the American healthcare system, the nonprofit advocacy group PatientRightsAdvocate.org (PRA) has filed a lawsuit against the American Medical Association (AMA). The suit, filed this week in the U.S. District Court for the Northern District of Illinois, seeks to dismantle the AMA’s exclusive copyright over the Current Procedural Terminology (CPT) code set—a proprietary system of medical billing codes that serves as the backbone of healthcare payments in the United States.
At the heart of the dispute is a fundamental question of public policy and intellectual property: Can a private organization claim ownership over a coding system that is legally mandated by the federal government? The outcome of this litigation holds the potential to force the AMA to release these vital codes into the public domain, potentially lowering administrative costs for hospitals, insurers, and patients alike.
The Core Conflict: Can You Copyright the Law?
The CPT system consists of thousands of five-digit codes used to describe every medical, surgical, and diagnostic service provided to patients. These codes are not merely industry standards; they are, in many respects, the law. Federal regulations and at least 15 state statutes incorporate CPT by reference, making the codes essential for compliance with billing requirements set by the Centers for Medicare & Medicaid Services (CMS) and private health plans.
PRA’s legal argument rests on the established doctrine that "no one can own the law." By embedding the CPT system into the regulatory framework, the government has essentially turned the codebook into a binding legal text. PRA argues that because the government requires providers to use these specific codes to receive payment, the AMA’s enforcement of copyright creates an "egregious" barrier to transparency and efficiency.
"The government made CPT codes part of the operating law of our health care system, but the AMA keeps it behind a paywall," said Cynthia Fisher, founder and chair of PRA, in a statement. "We are asking the court to affirm a basic principle: No one can charge the public to access standards that are incorporated into state and federal law."
A Chronology of Controversy
The current litigation is the latest chapter in a long-standing tension between the AMA’s private intellectual property rights and the public interest.
- 1997 – The Ninth Circuit Precedent: The legal theory underpinning the current lawsuit has a historical precursor. In the case of Practice Management v. American Medical Association, the Ninth Circuit Court of Appeals ruled that the AMA had misused its copyright. The court found that by entering into a deal with federal regulators that forced the agency now known as CMS to use CPT to the exclusion of any competing system, the AMA effectively gained a government-sanctioned monopoly.
- The Decades of Consolidation: Following the 1997 ruling, the AMA maintained its grip on medical billing by continuously updating the code set to reflect evolving clinical practices, effectively preventing alternative systems from gaining traction.
- 2025 – Financial Disclosure: Recent financial reports revealed that the AMA generated $296.4 million in revenue from "books and digital content," netting a profit of $267.5 million. Industry analysts widely attribute the vast majority of this revenue to the licensing of CPT codes, marking the system as a primary engine of the organization’s financial health.
- October 2026 – Congressional Scrutiny: Senator Bill Cassidy (R-LA) escalated the pressure on the AMA, sending a formal inquiry regarding the organization’s "government-backed monopoly." Cassidy demanded transparency regarding how the AMA calculates its fees and the extent of its revenue derived from the mandatory code set.
- May 2027 – The CMS Pivot: In a move that signaled shifting federal sentiment, CMS included a request for public comment in its proposed 2027 physician payment rule, specifically inviting industry feedback on the "harms or challenges" associated with the AMA’s licensing monopoly and the feasibility of utilizing alternative coding systems.
The Economics of the Monopoly
The financial barrier to entry for the medical community is significant. A single physical copy of the CPT codebook costs $137.89. However, the true costs are buried in the electronic infrastructure of healthcare. Practices that integrate CPT codes into their billing software are subject to an annual licensing fee of $82.50, plus additional user-based fees that scale with the size of the healthcare organization.
For a large hospital system or a multi-state health insurer, these cumulative fees translate into millions of dollars annually. PRA argues that these costs are ultimately passed down to patients and employers, inflating the already exorbitant price of American healthcare. By forcing stakeholders to pay for the "privilege of understanding" the laws governing their own medical bills, the AMA has created a recurring revenue stream that many critics view as an unnecessary tax on the industry.
Official Responses and Defense
The AMA has signaled that it will mount a robust defense, characterizing the lawsuit as an attack on the integrity of medical record-keeping. In a statement provided to MedCity News, an AMA spokesperson defended the organization’s stewardship of the CPT system.
"CPT serves as the uniform language of medicine, updated continuously through an open, transparent process that reflects evolving clinical care," the spokesperson stated. "The AMA brings expertise and scale to this work, convening collaboration across medicine, government, and industry. We will vigorously defend the AMA’s intellectual property rights to ensure the continued access physicians and patients rely on."
The AMA’s argument centers on the complexity of maintaining a medical lexicon that is accurate, safe, and up-to-date with current scientific advancements. They maintain that the revenue generated from the code set is reinvested into the administrative labor required to curate, update, and manage the system, thereby ensuring that the "language of medicine" remains consistent and reliable.
Broader Implications for Healthcare Transparency
The outcome of this case could have tectonic consequences for the healthcare industry. If the court rules in favor of PRA and finds that the CPT code set should be in the public domain, the following shifts could occur:
- Democratization of Data: Small practices, tech startups, and independent billing companies would be able to build tools that interact with medical billing systems without the heavy burden of licensing fees. This could lead to a surge in innovative software solutions designed to help patients understand their medical bills.
- Increased Transparency: If the codes are freely available, it becomes easier for patients and researchers to audit healthcare costs, compare prices for services across different providers, and identify discrepancies in medical billing.
- Disruption of the AMA’s Business Model: A loss of CPT-related revenue would force the AMA to reconsider its financial structure, as it would lose its most significant source of non-dues revenue.
- Federal Regulatory Shift: A ruling against the AMA would likely force CMS and other government agencies to adopt a more "open-source" approach to regulatory standards. It may set a precedent for other industries where private entities hold copyright over standards that have been incorporated into government regulations.
Conclusion: A Turning Point?
The litigation between PatientRightsAdvocate.org and the American Medical Association is more than a dispute over copyright; it is a confrontation over the nature of public utility in the digital age. As the healthcare system continues to grapple with rising costs and the demand for increased transparency, the question of whether a private trade group can gatekeep the very language of medical billing is moving from the fringes of legal theory to the center of national debate.
As the court weighs the "no one can own the law" argument, the healthcare industry waits to see if the CPT system will remain a proprietary asset or become a public utility. Regardless of the verdict, the scrutiny directed at the AMA’s monopoly suggests that the days of unchecked control over the CPT codebook may be numbered. The federal government’s newfound interest in alternatives indicates that even if the AMA wins in court, the regulatory landscape is shifting toward a more transparent, accessible, and potentially less expensive future for all participants in the American healthcare ecosystem.
