ABIM MOC and Continuing Education: Requirements for Internal Medicine Certification
ABIM MOC requires internists to complete continuing education and knowledge assessments to maintain board certification. Learn what the requirements involve.

The American Board of Internal Medicine (ABIM) Maintenance of Certification (MOC) program requires board-certified internists to engage in ongoing continuing education, medical knowledge activities, and periodic assessments to maintain their board certification. MOC is a structured framework for demonstrating that a physician's medical knowledge and clinical skills remain current throughout their career. Understanding MOC requirements is essential for any ABIM-certified internist planning their ongoing professional development.
ABIM MOC — Maintenance of Certification — is the program through which internists who have earned ABIM board certification maintain that credential over time. Initial ABIM certification, earned by passing the Internal Medicine Board Exam, demonstrates competency at the time of examination. MOC is the ongoing mechanism that ensures certified physicians continue to demonstrate currency in their knowledge and practice. The program has evolved significantly over the years, with ABIM updating requirements in response to feedback from internists and changes in how continuing medical education is delivered and assessed.
ABIM certification in internal medicine and its subspecialties was originally time-limited — certificates expired after ten years, requiring physicians to pass a recertification examination to maintain their credential. The MOC program replaced this strictly examination-based model with a continuous ongoing engagement framework. Physicians earn MOC points by completing medical knowledge activities, participating in practice improvement modules, and passing knowledge assessments. The shift from a decennial high-stakes examination to continuous engagement has been controversial among some internists, but the current MOC framework is the standard that all ABIM-certified physicians must meet to maintain certification.
The practical importance of maintaining ABIM certification affects physicians at multiple levels. Hospital credentialing committees, insurance payers, and state medical licensing boards may reference board certification status when making credentialing and privileging decisions. Physicians whose ABIM certification lapses may face complications at credential renewal, even if their actual clinical competency remains high. Understanding the MOC requirements and staying current with them is part of the administrative infrastructure of a practicing physician's career, not just a credential maintenance exercise.
The controversy around ABIM MOC among internists centers largely on concerns about the relevance and burden of the requirements relative to their clinical value. Some physicians argue that the time and cost of MOC activities diverts resources from patient care without meaningfully improving physician competency.
ABIM has responded to these concerns by revising the program over successive years, reducing assessment frequency and expanding the types of activities that count toward requirements. Regardless of where individual physicians fall in this debate, the practical reality is that MOC requirements exist and must be met to maintain board certification and the credentialing status that flows from it.
Physicians who are approaching the midpoint of their MOC cycle or nearing a knowledge assessment deadline often experience a time-compressed preparation challenge that differs from initial board certification preparation. The initial ABIM board examination is a defined event that candidates typically prepare for intensively over months. MOC requirements, by contrast, are spread across years and can be easy to defer until they become urgent. Building an annual review habit -- whether through conference attendance, journal CME, or dedicated self-assessment programs -- prevents the accumulation of a deferred MOC burden that must be resolved in a compressed timeframe.

ABIM MOC is the American Board of Internal Medicine's framework for ensuring that board-certified internists maintain medical knowledge and professional standards over the course of their careers. The program replaced the original time-limited certification model with a system of continuous engagement, requiring physicians to participate in medical knowledge activities, demonstrate clinical competency, and pass knowledge assessments on an ongoing basis rather than just at a single decennial examination.
MOC applies to physicians certified in internal medicine and in ABIM-certified subspecialties including cardiology, gastroenterology, infectious disease, pulmonary disease, nephrology, rheumatology, endocrinology, hematology and oncology, and many others. Each subspecialty certification has its own MOC pathway with subject-specific knowledge requirements, though the overall framework of activities, points, and assessments is consistent across ABIM's certification programs. Physicians certified in both general internal medicine and a subspecialty maintain separate MOC requirements for each certification.
ABIM has made significant changes to the MOC program in recent years, partly in response to physician feedback about the burden and relevance of certain requirements. The organization has sought to make MOC activities more directly relevant to clinical practice and less administratively burdensome. Physicians who last engaged with ABIM MOC requirements several years ago should check for updated requirements through ABIM directly, as the specific activities, point values, and assessment formats may have changed since their last review.
The relationship between ABIM MOC and hospital credentialing is worth understanding for practicing physicians. Most hospital medical staff offices require physicians to hold current board certification as a condition of privileges -- and some specifically require that certification be in the active MOC pathway, not merely grandfathered certification from before MOC requirements were implemented.
Physicians who are in MOC but behind on requirements may face complications at credential renewal even if their certification technically hasn't lapsed. Staying current with MOC requirements -- not just technically enrolled but actively earning points and completing assessments on schedule -- prevents credentialing issues that can arise from being behind on requirements. Physicians who are uncertain about their current MOC status can check the ABIM certification portal at any time to see their enrollment status, point totals, and any upcoming deadlines for assessments or attestations.
ABIM has updated MOC requirements multiple times in recent years. Requirements for medical knowledge activities, points thresholds, and knowledge assessment formats have changed. The information in this guide reflects the general framework; for current, specific requirements, always verify with ABIM directly at abim.org or through your certification portal. Requirements for subspecialty certifications may differ from general internal medicine MOC requirements.
ABIM MOC requirements are organized around several components that physicians must meet on an ongoing basis. The core requirements involve earning MOC points through approved medical knowledge activities, maintaining good standing as a physician (including an attestation process), and completing knowledge assessments that test current medical knowledge in the physician's certification area. The specific numbers of points required and the assessment formats have varied over time as ABIM has updated the program.
Physicians enrolled in ABIM MOC must earn a specified number of points over each rolling period through approved activities. These activities span multiple categories — medical knowledge activities, assessment, and practice assessment (previously called practice improvement). Points are tracked in the ABIM certification portal, allowing physicians to monitor their progress toward the required total throughout the cycle. The portal also identifies which activity categories still need points and what approved activities are available in each category.
The medical knowledge assessment component of MOC requires physicians to demonstrate current knowledge through a structured assessment. ABIM has offered several formats for this requirement over the years — from traditional high-stakes two-day examinations at Prometric testing centers to longitudinal knowledge check formats available online. The current assessment format available to MOC participants is an important practical consideration for physicians planning their MOC cycle, as the format affects preparation approach, scheduling, and the type of study that's most useful.
Professional standing requirements are also part of MOC. Physicians must attest to meeting professional standards, including having a valid medical license and no disciplinary actions. Physicians who have had state medical board actions may face additional review from ABIM regarding their MOC status. Maintaining professional standing is not just a MOC requirement but a prerequisite for the medical practice activities that MOC is designed to ensure remain competent.
The cost of ABIM MOC is a practical consideration for physicians. ABIM charges annual enrollment fees for MOC participation, and many MOC-approved educational activities also carry their own registration fees. The total annual cost of maintaining MOC enrollment varies based on which activities a physician chooses, but it represents a meaningful ongoing expense for practicing physicians particularly when combined with the time cost of completing activities.
Some physicians manage this cost by prioritizing free or low-cost MOC-designated activities such as journal CME and ABIM's own self-assessment modules over more expensive conference-based CME, though the optimal mix depends on a physician's practice context and learning preferences.
Physicians who hold ABIM certification in general internal medicine and one or more subspecialties face a multiplicative MOC requirement -- each active certification requires its own ongoing MOC engagement. A hospitalist physician certified in internal medicine and critical care medicine, for example, maintains two separate MOC pathways with separate point requirements, separate knowledge assessments, and separate professional standing attestations.
While there is some overlap in approved activities (an activity approved for both certifications counts toward both), the management of multiple MOC pathways adds administrative complexity. Some physicians choose not to maintain certification in subspecialties they no longer actively practice to reduce the ongoing MOC burden.

ABIM MOC Program Components
Earn MOC points through approved CME activities, self-assessment modules, journal-based CME, quality improvement projects, and other educational activities accepted by ABIM.
Demonstrate current medical knowledge through ABIM's assessment format — either a longitudinal knowledge check or a traditional examination, depending on the current MOC program structure.
Attest to maintaining a valid medical license, no disciplinary sanctions, and compliance with ABIM's professional standards throughout the MOC cycle.
Monitor MOC points, activity completions, and assessment status through the ABIM certification portal, which tracks progress toward requirements across all active certifications.
Medical knowledge activities are the primary way physicians earn MOC points. ABIM accepts a wide range of educational activities for MOC credit, including traditional continuing medical education (CME) activities, self-assessment programs, journal-based CME, online educational modules, and quality improvement activities with educational components. Many CME activities offered by medical societies, academic medical centers, hospital systems, and commercial medical education providers are ABIM-approved and include MOC credit designation in their activity listings.
The most efficient approach to accumulating MOC points is integrating MOC-eligible activities into ongoing professional development rather than trying to acquire all required points in a compressed period near a deadline. Physicians who attend major internal medicine conferences, participate in their specialty society's educational programs, and regularly complete journal CME activities as part of normal professional practice typically find that MOC points accumulate naturally over the year. Physicians who don't participate in structured CME regularly may need to more actively plan their MOC activity completion schedule.
ABIM has specifically expanded the types of activities that qualify for MOC points to include activities related to practice-based learning and quality improvement — recognizing that physician learning often occurs in the context of clinical practice improvement rather than solely through formal educational programs. Hospital-based quality improvement projects, peer review participation, and clinical data review activities may qualify for MOC points under certain ABIM-approved frameworks. Physicians in academic settings may also earn MOC points through teaching activities, depending on the specific program structure. The ABIM website maintains a directory of approved MOC activities and activity providers.
The role of medical society membership in MOC activity access is significant. Major internal medicine societies -- the American College of Physicians, the Society of Hospital Medicine, subspecialty societies like the American College of Cardiology or the American Gastroenterological Association -- offer extensive CME programs that include ABIM MOC-designated activities for members.
Physicians who are active in their specialty society and participate in society educational programs as part of ongoing professional development often find that their natural professional activities overlap significantly with MOC requirements, reducing the degree to which MOC feels like a separate administrative burden on top of their normal professional life.
Self-assessment programs deserve specific mention as a MOC activity category. ABIM offers self-assessment modules in various internal medicine and subspecialty content areas that combine educational content with formative assessment questions. These modules earn MOC points and also serve a genuine educational function -- the questions and explanations help physicians identify clinical knowledge gaps in a structured way. Physicians who use self-assessment modules regularly find them more educationally valuable than passive CME activities because the active retrieval practice required by answering questions produces stronger learning retention than passive reading or lecture attendance.

Not all CME activities count for ABIM MOC credit -- only activities that are specifically designated as ABIM MOC-approved. When registering for CME conferences, online modules, or journal CME programs, look for explicit ABIM MOC credit designation. Many providers list MOC credit amounts alongside AMA PRA Category 1 CME credit. Completing CME that isn't MOC-designated won't advance your MOC requirements even if it's educationally valuable.
The knowledge assessment component of ABIM MOC tests physicians on current internal medicine knowledge in their certification area. ABIM has moved away from the traditional two-day examination format that characterized its original board certification examination and recertification model, and now offers assessment formats designed to be more compatible with practicing physicians' schedules. The longitudinal knowledge check format allows physicians to answer questions over an extended period rather than in a single high-pressure examination session.
Preparing for ABIM knowledge assessments benefits from the same approach used for initial board certification preparation: targeted review of clinical medicine content, case-based question practice, and systematic identification of knowledge gaps. Physicians who engage regularly with medical literature and educational activities throughout the year may require less intensive dedicated assessment preparation than those who have been less engaged with structured learning. The assessment is designed to test the kind of current clinical knowledge that practicing internists should have -- not rare esoterica, but the clinical decision-making and diagnostic reasoning that internal medicine practice requires.
ABIM practice questions and question banks are available through several commercial medical education providers and through ABIM's own self-assessment resources. Using these materials specifically calibrated to ABIM content is more efficient than general medical review, because the ABIM assessment tests a specific body of knowledge with a specific clinical reasoning emphasis. Subspecialty physicians taking assessments for a subspecialty certification should focus their preparation on subspecialty-specific content while maintaining a foundation in general internal medicine principles that may also be assessed.
The assessment format changes ABIM has made over the past decade reflect a broader shift in how medical education and competency assessment are understood. The traditional high-stakes, time-limited examination that defined initial board certification has advantages -- it provides a clear, reliable snapshot of knowledge at a point in time -- but it also has limitations as a mechanism for ongoing competency assessment of practicing physicians.
Longitudinal assessment formats that distribute question-answering over time are designed to be more compatible with busy clinical schedules and to assess knowledge retention in a more ecologically valid way. Whether these alternative formats achieve their intended goals is an ongoing area of discussion within the medical education community.
ABIM practice resources are valuable whether you are preparing for an initial board exam or a MOC assessment. Question banks that reflect ABIM testing style, clinical vignette formats, and internal medicine content areas help physicians calibrate their knowledge before the actual assessment. Working through practice questions under timed conditions, reviewing explanations for both correct and incorrect answers, and identifying recurring knowledge gaps creates a targeted preparation process that is more efficient than comprehensive review of medical content without assessment practice.
