Every bowler knows the lane has boundaries. Staying in your lane is not a limitation — it is the condition that makes the game possible.
Clinicians decide what care to recommend. Payers decide what they will cover. These are different lanes. A common argument is that when a payer conducts utilization management, it is crossing into the clinician’s lane — that it is, in effect, practicing medicine.
It is not. And the law, with some important nuance, has largely agreed.
Why UM is not practicing medicine
Every state has a medical practice act. The details vary, but the core idea is familiar: Practicing medicine generally means diagnosing, treating, prescribing for, or otherwise directing the clinical care of a patient. In the ordinary malpractice setting, that judgment occurs within a physician–patient relationship, with a duty of care owed to the patient and accountability if the physician’s judgment falls below the applicable standard.
Utilization management has almost none of that structure. The reviewer has no treating relationship with the member. The reviewer is not diagnosing the condition, prescribing the treatment, or directing the clinician’s care. The reviewer applies pre-established coverage criteria to a documented request — asking whether the facts presented satisfy the plan’s conditions for payment. The output is a coverage determination. It is not a prescription, not a clinical order, and does not require a clinician to change a treatment recommendation. A clinician may pragmatically adjust a recommendation in response to a coverage determination — but that is a clinical decision, not a coverage decision.
The confusion is understandable because UM often involves medical judgment. Reviewers evaluate clinical information, apply evidence-based criteria, and make consequential decisions. But using medical judgment is not the same as practicing medicine. A hospital administrator reviewing readmission rates is working with clinical data. An actuary who prices coverage for oncology drugs is making assumptions about disease progression and treatment patterns. Neither is practicing medicine. The question is not whether medical knowledge informs the act. The question is whether the act itself directs the clinical care of a patient. UM does not.
This is where the argument often goes sideways. Those who say UM is practicing medicine are often less concerned with the definition than with the consequences: Bad UM can cause real harm, and the frustration that follows is legitimate. But frustration with how UM is performed in not evidence of what UM is. That distinction — between medical content and medical practice — is also the distinction the courts have generally preserved.
What the courts have said
The legal record on this question is not new. Two California cases from the 1980s set the framework that courts and regulators have worked within ever since.
In Sarchett v. Blue Shield of California (1987), the California Supreme Court recognized that an insurer may dispute whether a service is medically necessary for coverage purposes, even when the treating physician recommended it. The case also underscores the procedural obligation that comes with that authority: The plan must apply discernible standards and honor the member’s contractual review rights.
Wickline v. State of California (1986) introduces more complexity. A concurrent review decision by Medi-Cal shortened a patient’s hospital stay; complications followed, and the question of liability arose. The court emphasized the treating physicians’ responsibility, noting that they had not appealed the coverage decision despite disagreeing with it. The ruling drew a meaningful distinction: A retrospective denial withholds payment, while an erroneous prospective decision can effectively withhold care. The court did not classify the coverage determination as medical practice. Wickline placed substantial weight on the treating physician’s continuing duty to advocate for the patient, including through available appeal mechanisms. But it also remains important because it recognized that payers may face exposure when cost-containment decisions foreseeably affect care.
The federal courts added another layer in Corcoran v. United Healthcare (5th Cir. 1992). A utilization review organization denied hospital admission for a high-risk pregnancy and authorized home nursing care instead. The fetus died, and the family sued under state tort law. The Fifth Circuit did not pretend the decision lacked medical content. It said the opposite: United gave medical advice. But it gave that advice in the course of deciding what benefits were available under the plan, which brought the claim within ERISA’s framework. The court was candid about the tradeoff: ERISA preemption, it acknowledged, removes an important check on UM. United prevailed. Even where UM has medical content, the act being performed may still be benefits administration.
Taken together, these cases establish a durable, if imperfect, framework: Coverage determinations and treatment decisions are legally distinct acts, even when coverage review requires medical judgment. That distinction does not make UM harmless, and it does not excuse arbitrary denials. It means the legal question is more specific: whether the plan properly applied its coverage criteria, complied with required procedures, and gave the member a meaningful path to review.
What legislatures have done
With courts largely preserving that distinction, the policy fight has shifted to legislatures — and the picture there is more mixed, though not in the way the “UM is practicing medicine” advocates might hope.
That constraint has shaped what legislatures can actually do. For self-funded employer plans governed by ERISA — which cover roughly two thirds of workers with employer-sponsored coverage — federal preemption has largely closed the state tort liability route. States generally cannot allow members to sue those plans for malpractice arising from coverage decisions. That helps explain why the reforms gaining traction are procedural rather than liability-based: response time requirements, gold-carding, continuity provisions, clinician-reviewer requirements, and external review. They address how UM is conducted, not who can be sued when it goes wrong.
Response-time requirements set mandatory windows within which plans must act on prior-authorization requests — a recognition that delay can be as consequential as denial. Gold-carding programs exempt clinicians with strong approval track records from routine prior authorization requirements. Continuity provisions prevent plans from relitigating prior authorizations for members mid-treatment, protecting patients with ongoing needs from disruption during coverage transitions. Clinician-reviewer requirements mandate that the reviewer evaluating a request hold the same or similar credentials as the clinician who submitted it. External review gives members the right to have a coverage denial evaluated by an independent organization outside the plan. These are meaningful reforms — and they treat UM as a coverage function.
Texas shows how states can hold UM accountable without reclassifying it as the practice of medicine. The state has subjected UM to sustained legislative scrutiny over many sessions, requiring utilization review to be conducted under the direction of a clinician licensed to practice medicine in Texas and tightening who may serve in that role. That is meaningful clinical accountability.
The argument that UM constitutes medical practice has found some legislative sympathy in a small number of states, but it has not produced a durable statutory rule treating the two as the same. The more common outcome — across states with very different political dispositions toward payers — has been procedural reform aimed at making UM more transparent, more timely, and more clinically grounded. That addresses the legitimate critique without collapsing coverage review into medical practice.
Frustration is not a good reason to mischaracterize UM
UM can be done badly. But the answer to bad UM is better UM — qualified reviewers, evidence-based criteria, robust appeals, and genuine accountability when the process fails. Frustration with UM should not harden into the claim that it is “the practice of medicine.” Every lane has boundaries. The clinician’s lane and the payer’s lane are different. The honest and productive work is holding each accountable within its own domain — not erasing the line between them.
