What’s new for 2023?
- Sleep Medicine diplomates can choose the general Sleep Medicine LKA, or an Obstructive Sleep Apnea (OSA) version that has a greater number of questions on OSA, and also includes questions on bruxism, snoring, GERD and home sleep apnea testing. Overall, this version has an approximately 70% overlap with the general Sleep Medicine blueprint.
- Physicians practicing primarily in a hospital setting may be interested in inpatient-focused versions of the Internal Medicine LKA and traditional, 10-year MOC assessment launching in 2024. Learn more on our blog, including what you’d need to do in 2023 to ensure a seamless transition in the future.
- If you earned your ABIM certificate before 1990, you can try the LKA for MOC. Learn more about your options here.
Making our site accessible to everyone who visits it is an important inclusion effort for ABIM. To assess the current state of the ABIM.org website, we collaborated with the Carroll Center for the Blind (CCB) to determine our level of compliance with the Web Content Accessibility Guidelines (WCAG) 2.1. As part of the process, CCB assessed the full site, including the secure Physician Portal, to see how ABIM could improve in areas such as keyboard-only access, screen reader compatibility and touch access on mobile devices.


During the COVID-19 pandemic, ABIM extended deadlines for Maintenance of Certification (MOC) requirements for all disciplines through 2022; for Critical Care Medicine, Hospital Medicine, Infectious Disease and Pulmonary Disease, that deadline was extended to December 31, 2023. If you are in one of these disciplines you may have requirements to complete by the end of this year to remain certified. To find your specific due dates, please sign into your personalized Physician Portal.
The Longitudinal Knowledge Assessment (LKA®) is an MOC assessment option you may want to explore, with additional flexibility in when and where you can take questions. The first set of questions is available now through March 31, meaning if you’re interested there is still time to enroll and complete the first set of questions before they expire at the end of the quarter. You must be up to date on payments for all of your certificates to access the LKA, even if you are participating in just one discipline. The annual MOC fee is $220 for the first certificate you are maintaining, with a reduced fee of $120 for each additional certificate you are maintaining. You can find out if you owe any fees by signing into your Physician Portal and navigating to the “My Payments” section.- If you choose to take the traditional, 10-year MOC exam, there will be a $700 test center fee in addition to your annual fee. The test center fee is waived for Transplant Hepatology, Adult Congenital Heart Disease, Advanced Heart Failure and Transplant and Clinical Cardiac Electrophysiology because the LKA is not being developed in those specialties.
- When you are initially certified in Internal Medicine you will receive an MOC fee waiver automatically applied to your account for one year. Upon notification that you have successfully completed a year of an eligible fellowship program, ABIM will forgive one year of program/per certification fees.
In collaboration with practicing physicians, ABIM creates and administers at least 50 initial certification and traditional 10-year MOC assessments across nearly two dozen disciplines each year, and 15 Longitudinal Knowledge Assessments (LKA®) quarterly. This number continues to grow with the development of the LKA in additional specialty areas. For every assessment, each question is developed, reviewed, revised, approved, pre-tested and then discarded (if shown to not be working properly) or revised and tested again before finally appearing on an assessment as a scored question.

Each question is carefully considered from every angle: should every physician in this specialty area be able to answer the question without a reference? Is it relevant to the practice in that specialty? Is it a fair question? Is there more than one correct response? Is it biased? Does it require some thought and analysis? One question can take many revisions to get through the approval process and become a scored assessment question.
“It is critically important that question writers are trained to write fair and valid questions and that the process ABIM uses to develop and vet these questions is rigorous and thorough,” said Rebecca Lipner, Ph.D., Senior Vice President, Assessment and Research at ABIM. “By so doing, we can be assured that test takers are scored only on questions that have been put through the process and have been approved by experts in the field.”
