Start with a question that sounds rhetorical but is not. If a veterinary teleradiology company cannot match an ethical competitor’s price while following the same rules the competitor follows, what are its options? It can accept lower margins. It can operate at a smaller scale. It can find genuine efficiencies. Or it can lower its costs by not following the rules — by staffing interpretations with cheaper labor that the law does not actually permit to perform them, and by operating in places and ways the law does not actually allow. The first three options are competition. The fourth is something else.

This article is about the fourth option, and about why it is available in veterinary teleradiology in a way it is not available in human teleradiology. The two fields perform a nearly identical technical service: a radiologist, at a distance, interprets a medical image and renders a diagnostic opinion. The two fields are governed by the same underlying legal principles. But human teleradiology operates inside a dense, mature, actively enforced legal structure, and veterinary teleradiology operates inside the same legal principles with almost none of the enforcement. That gap is an opportunity, and the corporate aggregator model that dominates veterinary teleradiology has taken it.

What follows is a reference investigation. It documents how human teleradiology is regulated, the parallel legal principles that govern veterinary teleradiology, the specific and narrow ways the corporate aggregator model departs from those principles, why the conduct is dangerous, how it can be enforced, and what the penalties are. It does not publish a state-by-state compliance map, because the purpose is not to teach a non-compliant operation how to restructure. The purpose is to establish that the legal lines exist, that they are knowable, and that crossing them is a choice.

Licensure Follows the Patient

The foundational rule of human teleradiology licensure is simple to state and consequential in effect: the interpreting radiologist must be licensed in the state where the patient is located, not merely in the state where the radiologist sits. This is the policy position of the American College of Radiology and of state medical boards. The practice of medicine is understood, as a matter of settled regulatory position, to occur where the patient is at the time of the encounter — which means the radiologist interpreting an image of a patient in a given state is practicing medicine in that state and falls under that state’s medical board.

The consequence is that a human teleradiology operation reading for patients across many states must ensure each interpreting radiologist holds a license in each state where that radiologist’s patients are located. This is administratively burdensome and expensive — it is one of the real cost drivers of human teleradiology — and it is not optional. A radiologist reading for patients in a state without holding that state’s license is subject to discipline by that state’s medical board, and the operation employing that radiologist is exposed as well. The rule is enforced, and the enforcement is real.

A Comprehensive Bar on Financial Inducement

Human medicine is also governed by an overlapping federal and state framework that prohibits the financial conduct most likely to corrupt diagnostic referral. The federal Anti-Kickback Statute makes it a criminal offense to knowingly offer, pay, solicit, or receive remuneration to induce the referral of services reimbursed by federal health care programs; violation carries felony exposure, substantial monetary penalties, and exclusion from federal programs. The Stark Law separately prohibits a physician from referring patients for designated health services — a category that expressly includes imaging — to an entity with which the physician or an immediate family member has a financial relationship. State-level anti-kickback and fee-splitting statutes add a further layer.

The combined effect is that, in human medicine, the tying or bundling of diagnostic interpretation to other purchases, the payment of per-referral inducements, the splitting of fees with referral sources, and physician self-referral into imaging entities the physician profits from are all constrained — and, critically, are constrained by statutes that federal prosecutors and state attorneys general have the resources and the institutional will to enforce. A human teleradiology operation that built its business on kickbacks to referring physicians, or on bundling imaging interpretation into a package designed to capture referrals, would not be engaged in aggressive competition. It would be engaged in conduct that has sent people to federal prison.

This publication has documented the human-side financial framework in detail in its companion coverage — including the analysis of federal kickback prosecution and what it would mean applied to veterinary teleradiology, and the examination of the broader enforcement gap between human and veterinary medicine. The short version is that human teleradiology operates under mandatory licensure where the patient sits and a comprehensive, enforced prohibition on financial inducement. Those are the rules of the regulated side.

A Diagnostic Interpretation Is a Diagnosis

The veterinary side is not a legal vacuum. It operates under the same underlying principles as the human side — the principles are simply less enforced. Begin with the most basic one. Every U.S. jurisdiction defines the practice of veterinary medicine to include diagnosis. Most state practice acts go further and expressly include rendering advice, opinion, or recommendation regarding diagnosis or treatment; some are emphatic about it. A diagnostic radiology interpretation is, by its nature, a diagnosis. That is what the word “diagnostic” in “diagnostic radiology” denotes. A veterinarian who reviews a radiograph, a CT study, an ultrasound, or an MRI and renders an interpretation of what it shows is making a diagnostic determination — and is therefore practicing veterinary medicine.

This is not a contested proposition. It follows directly from the plain text of the practice acts. And it has a direct consequence: because a teleradiology interpretation is the practice of veterinary medicine, it is regulated conduct. It requires licensure. It is subject to the practice act of the relevant state. And the relevant state — as in human medicine — is the state where the patient is located. The practice of veterinary medicine occurs where the animal is. A veterinary radiologist interpreting an image of an animal located in a given state is practicing veterinary medicine in that state, and is subject to that state’s veterinary practice act.

The Consultation Exemption — What It Is, and What It Is Not

If every teleradiology interpretation is the practice of veterinary medicine in the state where the animal sits, how does any cross-state veterinary teleradiology happen lawfully without the radiologist holding a license in every state? The answer is the consultation exemption — and understanding it precisely is essential, because the corporate aggregator model depends on blurring exactly this point.

Most state veterinary practice acts contain a consultation exemption: a provision permitting a veterinarian who is not licensed in the state to consult with a veterinarian who is licensed in the state, without the consulting veterinarian obtaining in-state licensure. The exemption exists for a sound reason. A general-practice veterinarian facing a difficult case should be able to obtain specialist input — including radiology input — without the specialist needing a license in every state a consultation might come from. A properly licensed veterinary radiologist who consults with an in-state licensed veterinarian, where that in-state veterinarian has requested the consultation and retains the veterinarian-client-patient relationship and primary responsibility for the patient, is practicing lawfully. This is the legal basis for a large amount of entirely legitimate veterinary teleradiology, and nothing in this article suggests otherwise.

But the consultation exemption has two limits that matter here. The first: it protects consultation — advice to an in-state licensed veterinarian who holds the VCPR. It is not a general license to practice into the state. Several states expressly provide that a consultant who deals directly with the animal’s owner, independent of the in-state veterinarian, falls outside the exemption. The second limit is the decisive one for this article: the consultation exemption, in most states, extends only to a veterinarian licensed in another U.S. state. A minority of states extend it to Canadian provinces. Only a small number reach foreign-jurisdiction licensees at all. A consulting veterinarian who holds no U.S. veterinary license does not fit within the consultation exemption in the large majority of states — there is no qualifying license for the exemption to recognize.

The Unlicensed-Practice Problem

The corporate aggregator model in veterinary teleradiology — the model operated by the largest companies in the sector — is not inherently unlawful, and it is important to say so plainly. A corporate teleradiology company whose radiologists are appropriately licensed, and whose interpretations are delivered as consultation to in-state licensed veterinarians who hold the VCPR, is operating within the law. The problem is not the corporate form. The problem is the specific way the dominant aggregator model is actually operated, and it crosses the legal lines in two identifiable ways.

The first: the aggregator model routinely places interpretations into the minority of states whose law requires the interpreting veterinarian to hold that particular state’s own license — even for consultation — without holding it. A small number of states do not provide the broad consultation exemption that most states provide, or provide only a narrow or capped version of it. An aggregator routing reads nationally, optimizing for volume and cost, does not reliably stop at those states’ borders. When it places an interpretation into such a state with a radiologist who holds no license there and cannot claim the exemption, that interpretation is the unlicensed practice of veterinary medicine.

The second, and more universal, is the use of foreign radiologists who hold no U.S. veterinary license at all. This is where the analysis is cleanest and the violation most general. A teleradiology interpretation is a diagnosis; a diagnosis is the practice of veterinary medicine in the state where the animal is located; to perform it lawfully without that state’s license, the interpreting veterinarian must fit the state’s consultation exemption; and the consultation exemption in the large majority of states requires a U.S. veterinary license the foreign radiologist does not hold. The interpretation is therefore not exempt consultation. It is the practice of veterinary medicine by a person who is neither licensed nor exempt. That is the unlicensed practice of veterinary medicine, and it is a violation of state law in the large majority of states where it occurs — regardless of how the corporate teleradiology service characterizes the arrangement.

The AVMA Characterization Does Not Resolve It

It is sometimes suggested — and the suggestion is convenient for the aggregator model — that remote interpretation is not really the practice of veterinary medicine, and therefore that the licensure analysis above does not bite. That characterization cannot be reconciled with the law.

Every U.S. practice act defines the practice of veterinary medicine to include diagnosis. A radiology interpretation is a diagnosis. The veterinarian rendering it is therefore practicing veterinary medicine, and in the lawful case is doing so specifically as a consultant within the consultation exemption. The consultation exemption itself proves the point. A state legislature does not need to enact an exemption permitting unlicensed consultation unless consultation would, absent the exemption, be the practice of veterinary medicine requiring a license. The very existence of a consultation exemption in a state’s practice act is that legislature’s acknowledgment that consultation — including diagnostic consultation — is regulated practice. You do not write an exemption from a rule that does not apply.

So the accurate legal picture is not that remote interpretation sits outside the practice of veterinary medicine. It is the opposite: remote interpretation is the practice of veterinary medicine, lawful only when performed by an appropriately licensed veterinarian who either holds the relevant state’s license or fits within that state’s consultation exemption. A professional association’s general statement to the contrary does not change the statutory text, does not bind a state veterinary board, and does not create a defense to an unlicensed-practice charge. State practice acts are statutes. Association position statements are not. Where the two conflict, the statute controls — every time, in every state.

This publication has documented a related move in the commercial sphere. In its analysis of the IDEXX telemedicine contract terms, this publication examined how IDEXX, in its own contract language, disclaims that it is rendering a diagnosis. The disclaimer is the corporate version of the same maneuver: an attempt to capture the commercial benefit of selling diagnostic interpretations while contractually denying the diagnostic character that triggers practice-act obligations and liability. A diagnosis does not stop being a diagnosis because a contract says it is not one, any more than the practice of veterinary medicine stops being regulated because an association says remote interpretation is something else. The readers best served by that distinction — state boards, attorneys general, and the veterinarians who sign their names to these reports — should understand that the disclaimer is a characterization, and that the practice acts are law.

The Financial Conduct the Practice Acts Already Reach

The licensure problem is not the only line the aggregator model crosses. The financial conduct prohibited comprehensively in human medicine — fee-splitting, kickbacks, referral inducement, the tying and bundling of diagnostic services to other purchases — is also reached, on the veterinary side, by state law. A majority of states prohibit referral fee-splitting and rebates, several through an explicit prohibition written directly into the veterinary practice act, and the rest through the unprofessional-conduct authority of the veterinary board and the AVMA Principles of Veterinary Medical Ethics, which most boards adopt by reference and which state plainly that a veterinarian should not offer or receive any financial incentive solely for the referral of a patient.

This publication has documented that framework and the commercial conduct that runs against it at length: in the comprehensive analysis of kickbacks and fee-splitting in veterinary teleradiology, in the examination of the AVMA fee-splitting framework, in the coverage of the Nevada kickback enforcement gap, and in the analysis of how the IDEXX vertical-integration structure and the Mars-Antech corporate consolidation capture diagnostic referral revenue. The point for this article is narrower: the same aggregator model that generates unlicensed-practice exposure through its staffing choices also operates loyalty programs, bundled-service arrangements, and equipment-placement deals that present the fee-splitting and tying concerns the practice acts reach. The two problems share a root. Both are ways of lowering cost or capturing referral volume that an operation following the rules cannot match.

Why the Conduct Is Dangerous

The danger operates on two levels. The first is to the patient and the pet owner. The licensure system exists to give the public a specific assurance: that the person making a diagnostic determination about an animal has been vetted by a state board, holds a credential that can be checked, and is accountable to that board if the determination is negligent. When a diagnostic interpretation is rendered by a person not licensed where the animal is located — and in the foreign-radiologist case, by a person holding no U.S. veterinary license at all — that assurance is gone. No state board verified the person’s qualifications. No licensure accountability attaches if the read is wrong. The pet owner, and very often the referring veterinarian, has no way of knowing any of this. They are relying on a diagnosis the regulatory system never stood behind.

The second danger is to the market itself, and this is where the article’s title stops being rhetorical. A veterinary teleradiology provider that staffs every interpretation with an appropriately licensed veterinarian, holds licensure where its reads are delivered, and declines to route work to U.S.-unlicensed foreign radiologists carries a higher cost structure than a competitor that does none of those things. Licensure costs money and takes time. Appropriately licensed specialist labor costs more than U.S.-unlicensed labor. A provider that observes the legal lines is, in plain terms, penalized in the marketplace for compliance — and a provider that crosses them is rewarded with lower costs and fatter margins. That is a market in which cheating is not a deviation from the competitive strategy. It is the competitive strategy. And it punishes precisely the providers the public would, if it knew, most want to win.

How It Can Be Enforced

The enforcement pathways exist and are not exotic. State veterinary medical boards have disciplinary authority over the veterinarians they license, and in most states have authority to pursue the unlicensed practice of veterinary medicine directly — through cease-and-desist orders and through referral for prosecution. A board does not need new legislation to act; the unlicensed-practice prohibition is already in the practice act. State attorneys general have authority under unfair-and-deceptive-practices statutes that can reach undisclosed financial arrangements and the misrepresentation of who actually rendered a diagnostic service. Where interstate conduct is involved — and the corporate aggregator model is inherently interstate — additional federal hooks become available, as this publication has documented in its kickbacks investigation.

The honest current picture is that this enforcement authority has barely been used. A comprehensive review of state board actions over the past decade found essentially no public case of cross-border unlicensed-practice discipline in veterinary teleradiology — a near-empty docket. But the emptiness reflects a detection-and-resource gap, not a legal safe harbor, and the profession itself has said so: a state veterinary medical society wrote to its own board in late 2023 warning that out-of-state providers were operating into the state without licensure and without an enforcement response. The authority is real. The infrastructure exists. What has been missing is activity — and the conditions that have kept the docket empty are not guaranteed to persist. This publication’s analysis of the enforcement gap documents why the first wave of enforcement is more likely a question of when than whether.

What the Penalties Are

For the unlicensed practice of veterinary medicine, the exposure is serious. Four states — Florida, Michigan, Nevada, and New York — make unlicensed practice a felony. Other states treat it as a misdemeanor carrying fines and potential incarceration, layered with administrative penalties: cease-and-desist orders, monetary penalties per violation, and bars on future licensure. For a corporate operation, the per-violation structure matters — each interpretation rendered unlawfully is potentially a separate violation, and a national operation generates interpretations in volume. For fee-splitting and kickback violations, the penalties run through the veterinary practice act and the board’s disciplinary authority, and in states with explicit statutory prohibitions the conduct is a direct disciplinary ground; the licensed veterinarians who participate — including the in-state veterinarians who sign reports generated by the model — carry their own individual exposure.

That last point deserves emphasis. The corporate entity is exposed, but so is every individual licensed veterinarian whose name is attached to the arrangement. A licensed veterinarian who signs, adopts, or relies upon an interpretation rendered by a U.S.-unlicensed radiologist, presenting it as a proper diagnostic read, is not a bystander to the unlicensed-practice problem. The veterinarian is potentially aiding it — and aiding the unlicensed practice of veterinary medicine is itself a disciplinary ground in most states. The model does not just expose the corporation that built it. It exposes the licensees it depends on to function.

The Two Fields, Side by Side

The table’s final row is the heart of the matter. In human teleradiology, the legal structure is enforced uniformly enough that every competitor carries roughly the same regulatory cost — licensure where the patient sits, no kickbacks, no tying — and competition therefore happens on service, quality, and genuine efficiency. In veterinary teleradiology, the same legal structure exists on paper but is enforced so rarely that a provider willing to ignore it can operate at a structurally lower cost than a provider that follows it. That is not a level field with some cheaters on it. It is a field tilted, by the absence of enforcement, against the providers who comply.
