A medical license in the United States typically lasts two years. Most state medical boards use a biennial renewal cycle, a smaller group renews annually, and New Mexico is the outlier with a three-year term. No medical license is permanent anywhere in the country, and the exact length depends entirely on which state issued it.
License Length by State
The two-year cycle is the norm. California, Texas, Florida, New York, Ohio, and Illinois all issue licenses that expire every two years, and most other state medical boards do the same. Annual renewal is less common but not rare: Kansas renews every year and requires 50 CME hours annually, and certain osteopathic boards, including Nevada’s and Oklahoma’s, also operate on a one-year cycle. New Mexico stands alone with a triennial cycle.
The length of your license matters beyond the calendar. It sets how often you pay the renewal fee and how your continuing education hours are counted. A physician in a biennial state banks CME across two years; a physician in Kansas has to hit the number every single year. If you hold licenses in more than one state, you are managing separate expiration dates and separate CME totals at the same time.1Federation of State Medical Boards. Continuing Medical Education Board-by-Board Overview
What Renewal Requires
Continuing Medical Education
Nearly every board conditions renewal on continuing education. Of 67 licensing boards tracked by the Federation of State Medical Boards, 63 require substantial CME, meaning at least 15 hours per year.1Federation of State Medical Boards. Continuing Medical Education Board-by-Board Overview Totals vary widely. States on the lower end, like Arizona and Idaho, require 40 hours every two years. New Hampshire and New Jersey require 100 hours over the same two-year period. Most biennial states fall somewhere between those figures.
Many boards also require coursework on specific subjects. Pain management, opioid prescribing, and controlled substance practices show up in Alabama, Alaska, California, and elsewhere. Some states mandate one-time training on end-of-life care or human trafficking recognition. Separately, the federal MATE Act requires all DEA-registered practitioners to complete at least eight hours of training on opioid and substance use disorders when applying for a new or renewed DEA registration.2SAMHSA. Training Requirements (MATE Act) Resources The DEA training is a federal requirement tied to registration, not to state licensure, though some states allow it to count toward the CME total.
Renewal Fees
Fees vary enormously from one state to another. Wisconsin charges $60 per renewal period. California charges $1,151 and Rhode Island charges $1,090. Most states sit between $150 and $600 per cycle.3Federation of State Medical Boards. Licensure Fees and Requirements A $400 biennial fee works out to $200 a year; in the higher-fee states, you are paying more than $500 a year just to stay licensed.
Disclosures and Attestations
Renewal applications ask for current practice information, an attestation of good standing, and disclosures covering any disciplinary actions or criminal convictions since your last renewal. A handful of states require fingerprint-based background checks at renewal or at set intervals. A small number of states require proof of malpractice insurance as a condition of licensure; most do not. Hospitals generally require coverage as a condition of privileges, which creates a practical requirement even where the board itself does not impose one.
Missing the Deadline
What happens after the expiration date depends on the state. Some boards allow a grace period, often 30 days, during which you can renew by paying a late fee on top of the standard fee. Others treat the license as lapsed the moment it expires, with no cushion. There is no national rule.
The financial penalty is not the main concern. During any period when your license is lapsed, you cannot legally see patients, bill insurers, or prescribe medications. Practicing on an expired license is illegal in every state and can bring disciplinary action, fines, and criminal charges. Even a short gap tends to create credentialing problems with hospitals and insurance panels that outlast the renewal itself.
Inactive Status if You Stop Practicing
If you plan to step away from practice temporarily or permanently, most states offer an inactive or retired license status. It keeps you in the board’s system without active CME compliance, and the fees are typically lower than a full renewal. The trade is that you cannot practice, prescribe, or hold yourself out as an active physician while inactive.
Coming back from inactive status is generally much easier than reinstating a fully expired license. For short absences, many boards ask only for the standard renewal fee and current-period CME. Longer gaps bring more. Some states require physicians who have been inactive for three or more years to complete a re-entry program that includes supervised clinical practice.4Federation of State Medical Boards. Reentry to Practice Requirements for Physicians A few states treat anyone inactive beyond five years as a new applicant subject to current licensing requirements. If you know you will want to return, choosing inactive status instead of letting the license lapse saves substantial trouble later.
Reinstating an Expired License
Reinstatement after a full lapse is a separate process from renewal, and the hurdles rise with the length of the gap. For short lapses, boards typically allow reinstatement with additional CME and a penalty fee. Beyond two or three years, many states require a formal clinical skills assessment or a supervised practice period.
Some boards require physicians who have been out of practice for an extended period to pass the Special Purpose Examination, known as SPEX, administered by the Federation of State Medical Boards.5Federation of State Medical Boards. SPEX and PLAS SPEX is a one-day, computer-based exam with approximately 200 questions across five blocks, designed to test whether a physician’s core medical knowledge is still current.6Federation of State Medical Boards. SPEX Information Bulletin Osteopathic physicians may instead be directed to COMVEX, administered by the National Board of Osteopathic Medical Examiners. Each state board sets its own threshold for when these exams apply.
At the far end, Idaho treats a license canceled for more than five years as void, and the physician has to apply as a completely new applicant meeting current licensing requirements.4Federation of State Medical Boards. Reentry to Practice Requirements for Physicians A lapse on your record can also affect credentialing and malpractice coverage for years after you have been reinstated.
Multi-State Practice and the Compact
If you hold or want licenses in more than one state, the Interstate Medical Licensure Compact is worth knowing about, but it does not change how long any single license lasts. As of 2025, more than 40 states and territories participate, with 38 as full member states.7Interstate Medical Licensure Compact. IMLCC Member States The compact creates an expedited pathway to obtain licenses in multiple states through a single application. You pay a $700 fee to the compact, your home state verifies your credentials and issues a Letter of Qualification valid for 365 days, and you then pay each additional state’s standard licensing fee.8Interstate Medical Licensure Compact. Application Cost
Once you hold those licenses, each one renews on its own state’s schedule with its own CME requirements and its own fee. The compact speeds up initial licensure. It does not consolidate renewal, and it does not extend how long any one license runs.
