In most cases, doctors can see patients out of state only if they hold a medical license in the state where the patient is physically located at the time of the visit. Medical licensing in the United States is state-based, so a physician’s authority to practice stops at the border of the state that issued the license. A few pathways make cross-state care easier, and a narrow set of exceptions exists for emergencies, federal providers, and some follow-up situations, but the default rule is firm: the license has to match where you are sitting when care is delivered.
The Rule Follows the Patient, Not the Doctor
Every state runs its own medical board and sets its own licensing requirements. A doctor licensed in one state has no automatic authority to treat patients in another. What matters legally is where the patient is physically located when care happens, not where the doctor is or what state issued the patient’s insurance card.1Telehealth.HHS.gov. Licensing Across State Lines
That principle applies whether the doctor gets on a plane, picks up the phone, or opens a video visit. A surgeon in New York who flies to another state to perform a procedure needs a license in that second state. A psychiatrist in California conducting a video therapy session with a patient sitting in an apartment in Illinois is practicing medicine in Illinois and needs an Illinois license to do it legally.2Federation of State Medical Boards.

Telemedicine Doesn’t Change the Location Rule
Telemedicine follows the same licensing logic as in-person care. During the COVID-19 public health emergency, most states temporarily waived their requirements so out-of-state providers could help with surging demand. Those waivers have largely expired.
In their place, a handful of states now offer telemedicine-specific registrations that let out-of-state doctors deliver virtual care without going through full licensure. These registrations come with restrictions, such as caps on the number of patients or prohibitions on opening a physical office in the state, but they are faster and cheaper for physicians than obtaining a full license. Whether one of these registrations is available depends on the specific state where you are located.
The Interstate Medical Licensure Compact
The Interstate Medical Licensure Compact (IMLC) is the main reason it has become easier for doctors to hold licenses in several states at once. Rather than filing a separate application with each state, an eligible physician submits a single application through the compact’s central system, which verifies credentials and facilitates the issuance of full individual licenses by each member state the physician selects.3Interstate Medical Licensure Compact. Information for Physicians
Since its 2015 launch, the compact has grown to more than 40 member jurisdictions, including the District of Columbia and Guam. Once a doctor is qualified through the compact, individual state licenses typically issue within 7 to 10 days, compared with months under the traditional application route. For patients, the practical takeaway is that a doctor who says they can see you in your state through the compact should still hold an actual license issued by your state; the compact is a shortcut to that license, not a substitute for it.
VA and Military Doctors Are a Federal Exception
Physicians employed by the Department of Veterans Affairs can practice in any state regardless of where they hold their license, as long as they are acting within the scope of their VA employment. Federal law explicitly preempts conflicting state licensing requirements for these providers, so a VA physician licensed only in Maryland can treat a veteran in Texas through a VA telehealth program without a Texas license.4Federal Register. Authority of VA Professionals to Practice Health Care
This preemption covers physicians, nurses, and other health care professionals appointed under VA hiring authorities. It does not extend to contractors working in VA facilities or to community care providers the VA partners with. Similar federal authority covers active-duty military medical personnel treating service members and their families.
Emergencies and Established-Patient Follow-Up
Most states recognize a narrow exception for genuine medical emergencies. If a doctor encounters a patient in immediate danger of death or serious harm, providing life-saving treatment does not require a license in that state. The exception is meant for true emergencies and does not authorize any ongoing treatment once the crisis has passed.
A smaller number of states also allow limited follow-up care across state lines for established patients. The typical scenario is a patient who moves temporarily, such as a college student studying out of state or a retiree who spends winters elsewhere, and needs continuity with their existing doctor. These provisions vary widely: some states set tight time limits, others restrict the types of care allowed, and many have no such exception at all.5FSMB. States with Episodic and Follow Up Care Licensure Exceptions If you plan to rely on continuity with your regular doctor while you are out of state, ask directly whether the state you are traveling to permits it and under what conditions.
Controlled Substance Prescriptions Add a Federal Layer
Even when a doctor has the right state medical license, prescribing controlled substances across state lines involves separate federal rules. The DEA requires practitioners to hold a separate registration in each state where they dispense or prescribe controlled substances.6U.S. Department of Justice, Drug Enforcement Administration. DEA State Reciprocity So a doctor licensed and DEA-registered in Pennsylvania who picks up a New Jersey license through the IMLC still needs a separate New Jersey DEA registration before writing controlled-substance prescriptions for patients there.
Federal law also normally requires an in-person medical evaluation before a doctor can prescribe controlled substances by telemedicine, under the Ryan Haight Online Pharmacy Consumer Protection Act. A pandemic-era flexibility allows DEA-registered practitioners to prescribe Schedule II through V controlled substances via telemedicine without a prior in-person visit. That flexibility currently runs through December 31, 2026.7Federal Register. Fourth Temporary Extension of COVID-19 Telemedicine Flexibilities for Prescription of Controlled Medications If the DEA does not extend it again or finalize a permanent rule, the in-person requirement returns in 2027.
Insurance and Medicare Coverage Are Separate Questions
A doctor being legally allowed to see you across state lines does not automatically mean the visit is covered. Your health plan may treat an out-of-state provider as out-of-network even when that provider holds a valid license in your state, and out-of-network cost-sharing can run considerably higher. Check with your insurer before scheduling.
Medicare beneficiaries have broader telehealth access for now. Current rules allow Medicare patients to receive telehealth services from home with no geographic restrictions for non-behavioral care through December 31, 2027.8Telehealth.HHS.gov. Telehealth Policy Updates For behavioral and mental health telehealth, those geographic and location restrictions have been permanently removed, so Medicare patients can receive therapy or psychiatric care by video from anywhere in the country indefinitely.9CMS. Telehealth FAQ After 2027, non-behavioral Medicare telehealth is expected to revert to requiring the patient to be in a medical facility in a rural area, which would narrow access significantly.
What to Check Before an Out-of-State Visit
A few checks will save you real headaches, especially with telemedicine. Confirm your doctor holds a valid license in the state where you will physically be during the visit. Every state medical board runs a free online license verification tool. The location that counts is where you are sitting at the time of the appointment, not your permanent address.
Providers are expected to verify your location at the start of each telehealth appointment. If you travel frequently or split time between states, mention it when scheduling. A doctor licensed in your home state but not the state you are visiting cannot legally treat you during that trip, even if you have an established relationship. Scheduling appointments for when you are back in your home state avoids putting both you and your doctor in a difficult position.
Finally, if the visit is likely to involve a prescription for a controlled substance, ask whether the doctor is registered with the DEA in your state. A valid medical license alone is not enough for those medications.
