Licensure follows the patient
The location that matters for telehealth is generally the patient’s, not yours. Sitting in one state and caring for a patient in Oklahoma generally means you need authority to practice in Oklahoma — via compact privilege or an Oklahoma license. See telehealth: patient in another state.
The law that governs this in Oklahoma
Caring for a patient located in Oklahoma is practice in Oklahoma, so it is Oklahoma’s own nurse practice act that defines what you may do and the Oklahoma Board of Nursing that applies it. That act is 59 O.S. § 567.31 et seq. (Oklahoma Nursing Practice Act).
The compact itself is separate law. Oklahoma adopted it at 59 O.S. § 567.21 (Enhanced Nurse Licensure Compact), within the Oklahoma Nursing Practice Act at 59 O.S. § 567.1 et seq., which is what allows a multistate license issued elsewhere to reach Oklahoma at all — the practice act still decides what you may do once it does.
Compact status is not the only consideration
Even where a multistate license reaches Oklahoma, your employer and the Oklahoma Board of Nursing may impose additional requirements, and some roles carry their own rules. Compact status answers one question — it is not a blanket authorization to practice remotely.
APRN telehealth is separate
The compact covers RN and LPN/LVN licenses only. If you work as an APRN, your advanced-practice authority is granted state by state and is not carried by a multistate RN license — a point that catches out a lot of remote NP roles.
Since when has a compact license worked in Oklahoma?
Nurses holding another state’s multistate license have been able to practice in Oklahoma since January 19, 2018. It has been a member long enough that most guidance you find will be accurate on this point.
