A clinician who treats a patient by video has not necessarily cleared the legal bar to write that patient a prescription. Telehealth removes the need to be in the same room as a patient. It does not remove the requirement that a physician hold the license the patient's own state requires, or that a nurse practitioner or physician assistant hold the equivalent authorization their own licensing board requires, before treating that patient at all. A prescriber who writes for a patient in a state where they hold no license, no registration, and no compact privilege can face a board inquiry for the unlicensed practice of their profession, regardless of where the prescriber was sitting when the prescription was written. Clinicians searching for one national answer are really asking three separate questions, and each has its own answer.
Patient Location Sets the Prescribing Rule
State medical and nursing boards locate the practice of medicine where the patient is, not where the prescriber is. The Federation of State Medical Boards states the rule directly: a physician must be licensed, or specifically authorized, by the board of the state where the patient is located, because the practice of medicine occurs where the patient is located when telemedicine technology is used. Check a state medical board's own telehealth guidance for the same standard, and confirm the equivalent rule with a nurse practitioner's or physician assistant's own licensing board, since the licensing path differs by profession. A prescriber licensed only in a home state who treats a new patient physically located in a different state is practicing in that second state for licensing purposes. FSMB's model telemedicine policy recognizes a narrow exception for an existing patient who is only temporarily traveling, subject to conditions each state may or may not adopt. Before writing any prescription, the operative question is not where the prescriber is. It is where the patient is.
Interstate Compacts Do Not Replace a State License
A small number of interstate compacts exist to make multistate licensure faster, not to erase the underlying state-by-state requirement. The Interstate Medical Licensure Compact gives eligible physicians an expedited path to a full license in each participating state, not one license valid everywhere. The Nurse Licensure Compact lets a nurse with a multistate license practice in other compact states without a separate application, but membership is not universal and some states have not joined. A newer compact extends a similar privilege to physician assistants in the states that have enacted it. Before relying on any compact, a prescriber has to confirm, state by state, that the patient's state actually participates and that the prescriber's specific license or privilege is active there. The compact shortens the process. It does not substitute for checking the patient's state board.
Controlled Substances Add a Federal Layer
An ordinary, non-controlled prescription turns on state licensure alone. A controlled substance prescription adds a federal layer governed by the DEA, on top of whatever the patient's state separately requires for controlled substance authority. The DEA has kept its COVID-era telemedicine flexibilities for controlled substance prescribing in place through a series of temporary extensions, most recently through December 31, 2026, while a permanent special-registration framework remains unfinished. Because that framework is still in motion, a prescriber should confirm the rule in effect on the day of treatment rather than relying on what applied a year earlier. Prescribing Controlled Substances via Telehealth: The Current Rules covers that federal layer and the related state registration questions in depth.
The location of the patient, not the location of the prescriber, decides whose licensing law governs an ordinary telehealth prescription.
Why Early Legal Counsel Is Critical
It is critical that physicians, nurse practitioners, and physician assistants retain experienced healthcare defense counsel promptly once a multistate prescribing pattern is in question, whether the concern comes from a patient's travel, a compact gap, or a controlled substance prescription written across a state line. Early legal review can confirm which state's licensing rule actually governs a specific encounter, correct a prescribing pattern before a board frames it as unlicensed practice, and communicate with a board or state agency on the prescriber's behalf. Delaying legal review can turn a licensing question into a disciplinary proceeding with far fewer options.
How Health Law Alliance Can Help
Health Law Alliance has represented 2,500+ clients nationwide. The firm represents telehealth physicians and other prescribers who need a multistate prescribing practice reviewed before a board raises a question, and who need defense counsel once one has.
