Medical licensing boards are state agencies that decide who can legally practice medicine within their borders, set the standards doctors must meet to keep practicing, and investigate and discipline those who fall short. Every state, along with the District of Columbia and the U.S. territories, runs at least one such board. Their authority comes from each state’s Medical Practice Act, and they operate as the primary checkpoint between physicians and the patients they treat.
A few states run separate boards for MDs and DOs; most combine them. Either way, the board’s role is the same: issue licenses, keep a public record of who holds one, and act when something goes wrong.
Who Sits on a Medical Board
A typical board is made up of licensed physicians along with public members, appointed by the governor and often drawn from nominations submitted by the state medical association. Most boards include at least a few consumer representatives alongside practicing doctors. Members serve fixed terms and are responsible for setting policy, reviewing disciplinary cases, and approving or denying license applications.
Each board operates independently under its own state’s law, but they are not isolated from one another. The Federation of State Medical Boards (FSMB) coordinates across jurisdictions and maintains the Physician Data Center, one of the largest repositories of physician licensure, disciplinary, and demographic data in the country, covering more than one million practitioners.1Federation of State Medical Boards.

The Legal Authority Behind a Board
The Medical Practice Act in each state defines what counts as the practice of medicine, who is allowed to do it, and what happens when someone violates its terms. These statutes give boards broad administrative power: they interpret regulations, set standards for professional conduct, run hearings through administrative law processes, and impose discipline that can range from fines to permanent license revocation.2Federation of State Medical Boards. About Physician Discipline
One place that authority gets complicated is telehealth. The prevailing rule across all states is that the practice of medicine happens where the patient is located, not where the physician sits. Treating a patient by video in another state generally requires a license in that patient’s state, though some boards maintain special telehealth registries as a streamlined alternative to full licensure.
What Boards Require to Issue a License
Before a board will grant a license, an applicant has to put together a substantial file. The core requirements are consistent across jurisdictions:
- An MD or DO degree from an accredited program.3Federation of State Medical Boards. About Physician Licensure
- Passing scores on the USMLE (for MDs) or COMLEX-USA (for DOs).3Federation of State Medical Boards. About Physician Licensure
- Postgraduate residency training, usually one to three years in an ACGME- or AOA-accredited program.
- Full disclosure of hospital affiliations, prior employment, malpractice claims or settlements, and any criminal convictions.3Federation of State Medical Boards. About Physician Licensure
- A fingerprint-based FBI criminal background check.
Boards verify the important documents directly with the source. Medical schools send transcripts to the board, and exam scores arrive from the testing organization. Copies submitted by the applicant are not accepted. Physicians trained outside the United States or Canada must also have their credentials certified by the Educational Commission for Foreign Medical Graduates (ECFMG) before any state board will consider the application.4Intealth ECFMG. Requirements for ECFMG Certification
Many boards participate in the FSMB’s Uniform Application, a standardized form that reduces redundant paperwork for physicians applying in multiple states.5Federation of State Medical Boards. UA Participating Boards Each state still reviews and approves licenses on its own. Initial application fees vary widely, from as little as $35 to over $1,400 depending on the state.6Federation of State Medical Boards. Licensure Fees and Requirements Processing commonly takes one to four months once the board has every document in hand.
Practicing Across State Lines
Because every state licenses independently, a physician who wants to practice in multiple states has historically had to apply to each one separately. The Interstate Medical Licensure Compact (IMLC) was built to shorten that process. As of early 2026, 43 states and two U.S. territories participate.7Interstate Medical Licensure Compact.

Information for Physicians
The eligibility bar is higher than for a standard license. A physician needs a full, unrestricted license in a state of principal license, current board certification from an ABMS or AOABOS board, no history of disciplinary actions or criminal convictions, and must have passed each USMLE or COMLEX-USA component in no more than three attempts.8Interstate Medical Licensure Compact. Information for Physicians The initial Compact fee is $700, on top of whatever the destination state charges.9Interstate Medical Licensure Compact. What Does it Cost?
Keeping a License Active
A medical license is not permanent. Most states require renewal every one to three years, with two-year cycles being the most common. Renewal fees generally run several hundred dollars.
Every renewal cycle requires proof of completed continuing medical education. Hours vary: some states ask for as few as 30 per two-year cycle, others for 100, with 40 to 50 the most common range. As of 2026, 55 of 67 medical boards also require specific mandatory topics within those CME hours.10Federation of State Medical Boards. Continuing Medical Education by State Common mandated topics include opioid prescribing and pain management, medical ethics, implicit bias, patient safety, and recognition of child abuse or domestic violence.
Federal rules add another layer. The MATE Act requires every DEA-registered practitioner to complete a one-time, eight-hour training on treating patients with opioid or other substance use disorders as a condition of DEA registration.11DEA Diversion Control Division. Opioid Use Disorder – MATE Act This requirement is separate from state-level CME.
Missing a renewal deadline or letting CME lapse makes the license inactive or expired, which means no legally seeing patients until the physician is reinstated. Reinstatement usually involves back fees, overdue CME, and sometimes a board appearance.
How Boards Investigate and Discipline Doctors
Oversight continues after a license is issued. Boards investigate allegations of negligence, substance abuse, fraud, and unprofessional conduct. When a complaint prompts a formal investigation, board committees or administrative law judges review the evidence to decide whether the physician violated the Medical Practice Act.
Discipline is scaled to the finding:
- A letter of concern is the lightest response, a formal warning that does not restrict practice.
- Probation or mandatory remediation lets the physician keep practicing under conditions such as added education, monitoring, or treatment for substance abuse.
- Suspension prevents practice for a set period or until the physician meets specific board requirements.2Federation of State Medical Boards. About Physician Discipline
- Revocation terminates the license entirely.2Federation of State Medical Boards. About Physician Discipline
Reinstatement after revocation is not guaranteed and varies by state. Some jurisdictions allow a petition for reinstatement only if the original revocation order authorized it. Others permit a new application after a waiting period. Either way, the physician has to prove the underlying problem has been corrected.
National and Federal Reach
State action does not stay in state. Licensing authorities must report adverse actions to the National Practitioner Data Bank within 30 days. Reportable actions include revocation, suspension, reprimand, censure, probation, and any license surrender while under investigation. Hospitals with formal peer review processes must also report restrictions of clinical privileges lasting more than 30 days when based on professional competence or conduct.12National Practitioner Data Bank. What You Must Report to the NPDB The NPDB is not open to the public, but hospitals, health plans, and licensing boards query it during credentialing. Physicians can run a self-query to see what has been reported.13National Practitioner Data Bank. Self-Query Basics
Serious state discipline can also trigger federal exclusion. The Office of Inspector General at the U.S. Department of Health and Human Services can exclude physicians from all federally funded healthcare programs, including Medicare and Medicaid, when a state board has revoked, suspended, or accepted the surrender of a license for reasons related to professional competence, performance, or financial integrity. Probation, letters of censure, and conditions short of suspension do not trigger exclusion on their own.14Office of Inspector General. Working with State Health Care Professional Licensing Authorities For most physicians, losing the ability to bill federal programs is career-ending even if they hold a license somewhere else.
How the Public Uses a Medical Board
State boards maintain public databases where anyone can verify a physician’s license status, education, specialty certifications, and formal disciplinary history. The FSMB operates DocInfo.org, a national search tool that aggregates licensure and board action data across states.1Federation of State Medical Boards. Member Resources When a physician has been the subject of a board order, the details of the violation and the resulting discipline are typically posted on the state board’s website.
Boards also take complaints from the public. Filing one usually means completing a form that identifies the physician, the date of the incident, and a detailed description of what happened. Medical records or witness statements strengthen the submission. Investigative staff then evaluate whether there is enough evidence to open a formal case. Not every complaint results in discipline, but every complaint is reviewed, and a pattern of complaints against the same physician can trigger an investigation even when any single incident might not.
