In general, under 21 U.S.C. 829(e), a prescription for a controlled substance is valid only if the practitioner has conducted at least one in-person medical evaluation of the patient. An exception to this in-person visit requirement was enacted during the COVID-19 public health emergency. This exception, known as "telemedicine flexibilities," has been extended multiple times to allow for continuity of care as new regulations are developed.
For 2026, the Fourth Temporary Extension of COVID-19 Telemedicine Flexibilities for Prescription of Controlled Medications permits all controlled substances to be prescribed via telemedicine without an in-person medical evaluation until December 31, 2026. Most telemedicine controlled substance prescriptions are expected to be written pursuant to this fourth extension or 21 U.S.C 829(e).
However, the DEA and HHS have recently proposed and promulgated new telemedicine rules to replace the COVID-19 flexibilities and create new exceptions to 21 U.S.C. 829(e):
Expansion of Buprenorphine Treatment via Telemedicine Encounter went into effect on December 31, 2025. More information is available below. For 2026, unless a practitioner explicitly states a prescription was issued under this specific rule, buprenorphine prescriptions can be assumed to fall under the Fourth Temporary Extension of COVID-19 Telemedicine Flexibilities for Prescription of Controlled Medications, delaying the need to implement the additional requirements in the buprenorphine-specific rule.
Special Registrations for Telemedicine and Limited State Telemedicine Registrations is a proposed rule that would apply to all controlled substances. Until a rule is finalized by the DEA, the rule in effect continues to be the Fourth Temporary Extension of COVID-19 Telemedicine Flexibilities for Prescription of Controlled Medications.
