Senator Elizabeth Warren and Representatives Val Hoyle and Alexandria Ocasio-Cortez introduced a bill this month that would ban the corporate practice of medicine nationwide, with Senator Ron Wyden and Senator Jeff Merkley and Representative Suhas Subramanyam as co-sponsors. The Stop Corporate Takeovers of Physicians Act, S. 5419 in the Senate and H.R. 10444 in the House, would require that any entity owning or controlling a physician practice be majority-owned and majority-controlled by licensed clinicians. The sponsors cite the share of physicians who work for corporate entities, which they put at more than 80 percent today against 62 percent in 2019.
The headline provision is a ban that most states already have in some form. What makes the bill worth reading closely is its treatment of the arrangements that grew up around those state bans, and the enforcement machinery attached to them.
The structure the bill bans is already banned in most states
Corporate practice of medicine restrictions exist in the large majority of states and generally prohibit a business corporation from employing physicians or owning a medical practice. They are an old feature of state professional regulation, built on the idea that clinical judgment should not answer to a commercial owner. The bill would make that principle federal and uniform, and it closes what its sponsors call the friendly physician loophole, the arrangement in which a licensed physician holds nominal ownership of a professional corporation while a management company runs the business.
That arrangement exists because the state bans created demand for it. A private equity fund or a hospital system that wants the economics of a physician practice cannot own the practice directly in most states, so it contracts with one instead. The result is a two-entity structure: a professional corporation owned by a physician, and a management services organization that employs the staff, handles billing, negotiates with insurers and collects a management fee that captures most of the profit.
The management contract is where the control sits
The bill's operative language goes at the contract rather than the ownership certificate. It would bar management services organizations from controlling a practice through ownership interests, through financing acquisitions, or through de facto control over hiring and firing, staffing, schedules, compensation, revenue targets, billing and coding, pricing and payer contracting. It would also require physician owners to be licensed and practicing in a state where the practice delivers services and to be substantially engaged in providing care, which targets nominal owners who hold a title without seeing patients.
Health care law firms that have analyzed the text describe that de facto control section as the part that would change transactions most, because the ownership test alone would leave the management agreement as the place where control lives. Hooper Lundy and Bookman notes that the bill would outlaw the friendly physician and management services organization model nationwide rather than leaving it to state variation, and that the arrangement is the standard structure for private equity backed practices in states with strict rules. Nixon Peabody makes a similar point about the scope of the change, noting that the bill would reach arrangements that state law has permitted for years.
What a compliant arrangement would look like under that test is the question deal lawyers are working through. A structure that survived would need physician ownership that is real rather than nominal, a management fee that reflects the fair market value of the services provided rather than a residual claim on profits, and decision rights over clinical and operational matters that stay with the licensed owners. Those are changes to the economics of the deal, not cosmetic ones. The management fee is how a fund captures the return on a practice it cannot own, and a fee capped at the value of billing and administrative services would leave the practice's upside with the physicians who own it. That is close to the intended effect of the bill, which is why the analysis from the law firms frames the structure of future transactions, rather than the legality of past ones, as the thing to watch.
The drafting also picks up terms that appear in employment contracts. Noncompete agreements would be banned for physicians, with a limited exception for licensees who own at least 25 percent of a practice, along with nondisclosure and non-disparagement agreements. Clinical judgment would be protected from interference as a matter of federal law. Those provisions matter to physicians negotiating with a management company, because restrictive covenants are how a practice keeps a clinician from leaving with patients, and the exception for part-owners creates an incentive to give physicians a meaningful stake rather than a nominal one.
Enforcement is the part with teeth
The bill does not leave enforcement to a single agency. It would treat violations as unfair or deceptive acts under the Federal Trade Commission Act, allow state attorneys general to sue, and create a private right of action with treble damages. Courts could order divestiture and disgorgement, and violators could be excluded from federal health care programs, which for a practice that relies on Medicare and Medicaid is the most consequential remedy in the list.
That combination is unusual in health care regulation, where oversight usually runs through payment rules and licensing boards. A private right of action with treble damages would put enforcement in the hands of physicians, competitors and possibly patients rather than a federal agency with limited staff. The exclusion remedy would reach the business model directly, because a management company whose practices cannot bill federal programs loses most of its revenue. For a hospital system weighing how much risk to carry in an existing structure, the enforcement section is likely to matter more than the ownership test itself.
The carve-outs show who the sponsors expect to keep operating
The bill exempts nonprofit and public health care providers, hospitals, hospital affiliated clinics, critical access hospitals and rural emergency hospitals. Those carve-outs preserve the arrangements that most states already treat as acceptable, and they leave the bill aimed at the investor-owned segment of the market rather than at health systems broadly. A rural hospital that employs physicians through a clinic structure would not be affected, while a private equity backed practice with a management company would be.
The line between the two is where the practical arguments sit. Supporters of the bill say the investors who buy practices raise costs by consolidating markets and by pushing physicians toward higher volume and more procedures, and they point to the ownership statistics as evidence of how far the shift has gone. Opponents say private capital keeps struggling practices open, that management companies provide the billing and administrative capacity small practices cannot afford, and that a federal ban would reduce the number of buyers available to physicians who want to sell. Both claims are contested in the research literature, and the bill does not attempt to resolve the empirical dispute so much as to pick a side of it.
The states have been the laboratory for this, and the bill borrows from it
The federal bill did not appear out of nowhere. States have spent several years tightening the rules around physician practice ownership, and the sponsors describe their text as building on that work rather than replacing it. Oregon passed a law in 2025 restricting private equity ownership and control of medical practices, and it is the model the sponsors cite most often. Other states have gone at the same problem through different instruments: some have written the corporate practice doctrine into statute, some require advance notice or review of health care transactions above a size threshold, and some have given attorneys general explicit authority to challenge deals on competition grounds.
The result is a patchwork in which the same transaction can be lawful in one state and exposed in another. For a fund that operates across state lines, that means complying with the strictest rule it touches, which is the uniformity argument the sponsors make for a federal standard. The bill also preserves stricter state laws rather than displacing them, so a state that has gone further than the federal text would keep its own rules in force.
The patchwork has a second effect that matters more in the short term. State attorneys general and medical boards already have authority over these arrangements under existing law, and the Hooper Lundy analysis points to state enforcement rather than the federal bill as the nearer term risk for practices that operate today. A structure that has been permitted for years is not the same thing as a structure that has been tested, and state regulators do not need Congress to act before testing one.
What the legislative calendar says about the odds
The bill was introduced on September 16 with a short legislative calendar remaining, and lawyers analyzing it for clients have been careful to frame it as a marker rather than a likely enactment. Seyfarth describes it as a possible shift in health care private equity rather than an imminent change in law, and the Hooper Lundy analysis argues that state enforcement is the nearer term risk for existing structures, because state attorneys general and medical boards already have authority over the arrangements and do not need new legislation to act.
That framing is the useful way to read the bill for anyone who follows consolidation in medicine. The Mavengity coverage of private equity deal counts made the point earlier this month that deal data labeled private equity fell from 851 to 105 as states tightened their rules, while the underlying consolidation continued under other labels. A federal ban on the paper structure would push the same economics in the same direction, toward contracts and structures that fall outside the definition. The reason the enforcement section matters so much is that a rule aimed at a structure is only as strong as its ability to see through the next arrangement built to avoid it.
The bill's path, if it has one, runs through the same question that has shaped the state laws: whether regulation can reach the control that a contract conveys as easily as the ownership that a certificate records. The sponsors have written the text to try. Whether a future Congress and the courts agree is a separate matter from whether the practices themselves would change if they did.
