Telehealth Across State Lines

Telehealth erases distance — but not state borders. The rules that govern where a provider can legally practice medicine are set at the state level, and they follow the patient, not the screen. Understanding these rules helps you anticipate when cross-state care will work, when it will not, and how ongoing regulatory changes may affect your options.

The patient-location rule: where you are is what matters

The foundational rule in U.S. medical licensing is that a provider must be licensed in the state where the patient is physically located at the time of the visit. Not where the provider’s office is. Not where the patient is normally a resident. Where the patient is sitting during the appointment.

This means a physician licensed only in California cannot legally conduct a telehealth visit with a patient who is in Texas — even if the patient is a California resident just visiting. It also means a New York psychiatrist cannot treat a patient who has moved to Florida without a Florida license, regardless of how long the therapeutic relationship has been established.

The reason for this rule is that state medical boards license, regulate, and discipline providers within their jurisdiction. A state can only enforce its standards on providers who hold its license. When the patient is in a state, that state’s standards should apply.

What the Interstate Medical Licensure Compact does

The IMLC was created to reduce the friction of multi-state licensing without eliminating state authority over practitioners. Here is how it works:

1. A physician establishes a state of principal licensure — typically the state where they live, practice most, or pay taxes.
2. The physician applies through the IMLC portal, designating additional participating states where they want to practice.
3. Those states can issue a license — through a streamlined process — based on the physician’s established qualifications, rather than requiring a full independent application to each state.

The result is that a physician with a principal license in Ohio can, through the IMLC, obtain licenses in dozens of other member states much more quickly than through individual state applications. This has expanded the pool of providers who can legally offer telehealth to patients in multiple states.

Important: the IMLC is for physicians (MDs and DOs). Other professions — nurse practitioners, therapists, psychologists, physician assistants — have their own separate compact agreements, each with different membership and rules. The Nurse Licensure Compact (NLC) covers RNs and LPNs across participating states, allowing nurses to practice under a multi-state license. Other compacts for psychologists (Psychology Interjurisdictional Compact, PSYPACT), counselors, and physical therapists are expanding but at varying stages of adoption.

How to find out if your provider can see you

If you are moving to a new state, traveling, or starting with a new telehealth provider, ask these questions directly:

Question	Why it matters
Are you licensed in [my state]?	The basic legal requirement
Are you licensed through the IMLC?	May speed up or already cover your state
Does your practice accept patients in my state?	Licensure is necessary but not sufficient; the practice must also be administratively set up to bill and operate in your state
Will my insurance cover this visit?	Your plan’s network may not include out-of-state providers even if they are licensed in your state

Asking these questions before booking — not during or after — prevents the situation where a visit is completed but a prescription cannot be sent or a claim cannot be filed.

Controlled substances and the Ryan Haight Act

Prescribing controlled substances via telemedicine involves a separate set of federal rules layered on top of state licensing requirements. The Ryan Haight Online Pharmacy Consumer Protection Act of 2008 made it illegal to prescribe a Schedule II–V controlled substance via the internet without a prior in-person medical evaluation — meaning the provider saw the patient physically before the remote relationship was established.

This rule has significant practical consequences for:

• Patients seeking ADHD medications (Schedule II stimulants like amphetamines)
• Patients receiving opioid prescriptions remotely
• Mental health patients whose treatment includes benzodiazepines or other scheduled drugs

COVID-19 waivers: In March 2020, the DEA used its emergency authority to allow providers to prescribe controlled substances via telemedicine without a prior in-person visit, effectively waiving the Ryan Haight Act’s in-person requirement during the public health emergency. These waivers allowed telehealth mental health and addiction medicine services to scale dramatically.

Status as of 2026: The DEA has been developing a permanent telemedicine special registration program that would allow providers who complete a specific registration process to prescribe controlled substances via telemedicine without a prior in-person visit, subject to conditions. Final rules were not settled as of September 2026. The DEA’s own website and the HHS telehealth policy portal are the authoritative sources for current status — the rules in this area have changed multiple times since 2020, and they may change again.

Documents and terms you’ll see

When researching cross-state telehealth, you will encounter these terms in regulatory and provider communications:

• Interstate Medical Licensure Compact (IMLC) — the multi-state physician licensing agreement; check whether your provider and your state participate
• Ryan Haigh Act — the federal law requiring in-person evaluation before controlled substance prescribing via telemedicine; check current DEA rules for the latest exemptions
• State medical board — the licensing authority for physicians in each state; can verify whether a provider holds a valid license in your state
• Nurse Licensure Compact (NLC) — the compact for RNs and LPNs; similar in purpose to the IMLC but for nursing professionals

Practical steps if you need cross-state telehealth care

1. Verify licensure before the visit. You can look up a provider’s license status through your state’s medical board website. Most boards have a public license lookup tool.
2. Contact your insurer. Confirm the out-of-state provider is in-network, or understand your cost-sharing if they are out-of-network.
3. Ask about controlled substance policies. If you need a prescription for a scheduled medication, confirm upfront whether the provider can legally prescribe it to you via telemedicine under current federal rules.
4. Plan ahead for moves. Contact your current providers before you relocate. Multi-state licensed providers may be able to continue care; others may need a transition period.
5. Consider IMLC-savvy telehealth platforms. Many national telehealth services have built their provider networks specifically to hold licenses across multiple states, making cross-state care easier.
