The Interstate Medical Licensure Compact: Faster Multi-State Licensure for Telehealth
How the IMLC works, who qualifies, what it costs in time, and where it helps — plus the nurse and psychology compacts that cover other clinicians.
Telehealth made multi-state licensure a routine operational problem rather than an edge case. A physician seeing patients in six states needs a license in all six, because licensure follows the patient's location, not the clinician's. The Interstate Medical Licensure Compact exists to make that a manageable process instead of six separate ordeals.
What the compact actually does
The IMLC is not a national license. It is an expedited pathway: one state acts as your State of Principal Licensure and verifies your eligibility once, after which participating member boards issue full, unrestricted licenses in their states without repeating the whole review. You end up holding several ordinary state licenses, each renewable and each subject to that state's board — you just obtain them far faster.
Eligibility is stricter than a normal application
- A full, unrestricted license in a member state that qualifies as your State of Principal Licensure
- Graduation from an accredited medical school and completion of accredited graduate medical education
- Current specialty certification or time-unlimited certification by an ABMS or AOA board
- No history of discipline on any license and no disciplinary action pending
- No criminal history and no current investigation by a licensing or law enforcement body
- A clear controlled-substance record with the DEA
A single past disciplinary action, however minor or old, generally removes the compact route. Those physicians apply to each state board directly, which is slower but still available.
How the process runs
- Designate your State of Principal Licensure — usually where you live, work the majority of your practice, or file taxes.
- Apply through the compact commission and pay the application fee.
- Your SPL board verifies eligibility and issues a Letter of Qualification, generally valid for a limited period.
- Select the member states you want licenses in and pay each state's licensing fee.
- Member boards issue the licenses, commonly within days to a few weeks rather than months.
Licensure is not credentialing
A compact license gets you legally permitted to practice in a state. It does not enroll you with that state's Medicaid program, add you to a commercial panel, or grant hospital privileges. Each new state still needs its own payer enrollment, and that work runs on its own 60-to-120-day clock. Telehealth groups that expand quickly usually sequence licensure and payer credentialing in parallel from the first day, rather than waiting for licenses to land before opening applications.
Compacts for other clinicians
- Nurse Licensure Compact — a multi-state privilege for RNs and LPN/VNs based on a single home-state license.
- APRN Compact — a separate, more recent framework for advanced practice registered nurses.
- PSYPACT — interjurisdictional telepsychology and temporary in-person practice for psychologists.
- PT, OT, counseling, and EMS compacts — each with its own membership list and privilege mechanics.
Ongoing obligations
Every compact license renews on its issuing state's schedule and its own fee. Continuing education requirements vary by state, and discipline in any one state can cascade to the others. Track renewals per state in whatever system holds your expirables, and reconfirm the current member-state list before planning an expansion — membership changes as legislatures act.
The compact compresses months of licensure into weeks. It does nothing to compress payer enrollment — so start both on the same day.
Frequently asked questions
- Is the Interstate Medical Licensure Compact a national medical license?
- No. It is an expedited application pathway. You receive separate full licenses from each participating state, each with its own renewal, fees, and board oversight.
- How fast is a compact license compared with a standard application?
- Once your Letter of Qualification is issued, member states commonly issue licenses within days to a few weeks, against several months for a conventional state-by-state application.
- Who is not eligible for the IMLC?
- Physicians with any history of license discipline, pending investigations, criminal history, or controlled-substance actions generally cannot use the compact and must apply to each board directly.
- Does a compact license let me bill payers in that state?
- No. Licensure and payer enrollment are separate. Each state still requires its own Medicaid enrollment and commercial payer credentialing, which typically takes 60 to 120 days.
