Telepsychiatry across state lines: licenses, DEA and controlled substances

Licenses: the patient's state decides

For telehealth, HHS says a clinician must be licensed or legally permitted to practice in the state where the patient is located. A psychiatrist in Texas seeing a patient who is in Colorado needs a Colorado license, whatever state the practice is based in.

The Interstate Medical Licensure Compact speeds this up but does not merge it. The Compact is a voluntary, expedited pathway: a physician who qualifies through a state of principal license receives a separate license from each participating state, and each one renews on that state's own schedule and rules. There is no single "Compact license." The Letter of Qualification is valid for 365 days, and the Commission charges $700 plus each state's license fee. Participating states are listed on the Commission's official site, imlcc.com ↗.

PSYPACT is for psychologists. It authorizes eligible psychologists to practice telepsychology across member states; it does not cover psychiatrists or psychiatric nurse practitioners (HHS ↗).

DEA registration: one in each state where you prescribe

DEA regulations require a separate registration for each principal place of business or professional practice (21 CFR 1301.12 ↗). DEA's telemedicine guidance applies that to telehealth: asked whether a practitioner needs a separate DEA registration in the state where patients are located, DEA answers yes, with certain limited exceptions (DEA Q&A ↗).

The COVID-era exception that let practitioners prescribe into other states on one registration applied for the duration of the public health emergency. The telemedicine extensions since then cover the in-person visit requirement, not per-state registration, so plan on a DEA registration in each state where you prescribe controlled substances. Each one runs on its own 3-year cycle.

Many states also issue their own controlled-substance registration on top of DEA, on their own cycles. Check each state's board of pharmacy, board of medicine or health department.

Prescribing controlled substances without an in-person visit

The Ryan Haight Act makes a prescription for a controlled substance delivered by means of the Internet valid only if the prescriber has conducted at least one in-person medical evaluation, unless an exception such as the "practice of telemedicine" applies (21 U.S.C. 829(e) ↗). Where things stand on September 27, 2026:

• Through Dec 31, 2026
  The Fourth Temporary Extension

  DEA and HHS extended the COVID-19 telemedicine flexibilities through December 31, 2026. Until then, a DEA-registered practitioner may prescribe Schedule II–V controlled substances by telemedicine without a prior in-person evaluation, for a legitimate medical purpose, through an interactive telecommunications system, and otherwise consistent with DEA rules.

  42 CFR 12.1 ↗
• Proposed only
  Special registration for telemedicine

  DEA proposed a special registration for telemedicine on January 17, 2025. As of September 27, 2026 it had not been finalized. What replaces the flexibilities after December 31, 2026 depends on DEA's next action; check before January 1, 2027.

  Federal Register ↗
• In effect
  Buprenorphine for opioid use disorder

  A separate DEA final rule permitting buprenorphine for opioid use disorder via telemedicine, with its own conditions, took effect on December 31, 2025, alongside a rule for VA continuity of care.

  Federal Register ↗

Medicare tele-mental health

For Medicare patients, the patient's home counts as a site of care for mental and behavioral health permanently, and audio-only mental health visits are permanently allowed. The in-person visit Medicare would otherwise require within 6 months before an initial tele-mental health service, and yearly after, is not required through December 31, 2027 (HHS ↗; CMS FAQ, Feb 2026 ↗).

Commercial payers and state Medicaid programs set their own telehealth rules.

A per-clinician checklist for a telepsychiatry group

• Each patient state
  A medical (or APRN) license

  In every state where patients are located during visits, each on its own renewal cycle and CME rules.

  CME requirements by state
• Each prescribing state
  A DEA registration

  In every state where the clinician prescribes controlled substances, each renewing every 3 years.

• Where required
  A state controlled-substance registration

  Many states issue their own, with their own renewal dates, separate from DEA.

• Each renewal
  State-mandated CME

  Including opioid and controlled-substance prescribing CME in the states that require it; a few states accept only board-approved courses.

  Opioid & controlled-substance CME by state
• Before Jan 1, 2027
  The DEA telemedicine rule that replaces the extension

  Plan for whatever DEA publishes before the current flexibilities end on December 31, 2026.

Frequently asked questions

Which state license do I need to see a patient by telehealth?

A license in the state where the patient is located at the time of the visit. HHS states that clinicians must be licensed or legally permitted to practice in the state where the patient is located; a license where the clinician sits is not enough.

Can I prescribe controlled substances by telemedicine without an in-person visit in 2026?

Yes, through December 31, 2026, under the DEA and HHS Fourth Temporary Extension of the COVID-19 telemedicine flexibilities (42 CFR 12.1), if the prescription is for a legitimate medical purpose, is issued through an interactive telecommunications system, and is otherwise consistent with DEA rules. DEA's proposed special registration rule for telemedicine had not been finalized as of September 27, 2026, so check for DEA action before January 1, 2027.

Do I need a DEA registration in every state where my patients are?

Generally yes. DEA's telemedicine guidance says a practitioner needs a separate DEA registration in the state where the patient is located, with limited exceptions, and its regulations require a separate registration for each principal place of professional practice. The COVID-era cross-state exception applied only for the duration of the public health emergency.

Does the Interstate Medical Licensure Compact give me one license for every state?

No. The Compact is an expedited pathway: each participating state still issues its own separate license, which renews under that state's rules. Physicians do not receive a single Compact license. The Letter of Qualification is valid for 365 days, and the Commission's fee is $700 plus each state's license fee.

Does PSYPACT cover psychiatrists?

No. PSYPACT authorizes eligible psychologists to practice telepsychology across member states. Psychiatrists are physicians and need a medical license in each patient's state, which the Interstate Medical Licensure Compact can speed up.

Does Medicare still require an in-person visit before tele-mental health?

Not through December 31, 2027. CMS says the in-person visit within 6 months before an initial tele-mental health service, and annually after, is not required until then. The patient's home as the site of care and audio-only services for mental health are permanent.
