California CME requirements for radiologists
California sets one CME total for physicians in every specialty: 50 hours every 2 years, with 4 mandated topics. As a radiologist you also keep up ABR Continuing Certification. Below: both, and where one certificate counts for each.
California: the state rule
Checked against the Medical Board of California's rules on October 13, 2026. Citation: Cal. Bus. & Prof. Code ยงยง2190.5, 2190.6.
General CME: 50 hours AMA PRA Category 1 every 2 years.
Opioid / controlled substance
12 hours one-time (by 2nd renewal / within 4 years): pain management and care of the terminally ill, including Schedule II addiction risk. Trigger: all except pathologists & radiologists.
No board pre-approval needed, but the course must reach 12 hours and cover pain + end-of-life; the 8-hour core needs a CA addendum. Content gap, not an approval gap.
Mandated topics, and whether each reaches radiologists
| Topic | Hours | Timing | Who it applies to | For radiologists |
|---|---|---|---|---|
| Pain management and care of the terminally ill (including Schedule II addiction risk for post-2019 licensees) | 12 | one-time (by 2nd renewal / within 4 years) | all except pathology/radiology | Does not apply to radiologists: the page exempts pathologists and radiologists. |
| Geriatric medicine / dementia | At least 20% of hours (about 10) | per cycle while condition applies | IM/FM with >25% pts 65+ | Unlikely: the page limits this to internal medicine and family medicine physicians. |
| Cultural & linguistic competency | embedded course content (no add-on hours) | ongoing (since 7/1/2006) | all courses | Applies to all physicians. |
| Implicit bias | embedded course content (not standalone) | ongoing (since 1/1/2022) | all courses | Applies to all physicians. |
Notes from the California page
- Total is 50 hours (some summaries say 100). Implicit bias and cultural competency are course-content mandates, not extra hours. No standalone recurring opioid CME.
- DOs: the figures above are the Medical Board of California's. Osteopathic requirements now diverge. The OMBC conformed to statute effective October 1, 2025: 50 hours per 2-year cycle with at least 20 AOA Category 1-A, plus new mandated topics. Verify with the Osteopathic Medical Board of California.

Your board: ABR Continuing Certification
Board figures as tracked in the Ledger, last checked October 15, 2026. Confirm in your board portal.
The American Board of Radiology (ABR) asks diagnostic radiologists for at least 75 AMA PRA Category 1 CME credits in any rolling 3-year period. Newly certified diplomates start counting in their fourth year of participation.
You also answer Online Longitudinal Assessment (OLA) questions and meet the passing standard by year 5 of the 5-year cycle (or pass an exam in year 4 or 5), complete one Practice Quality Improvement project or participatory QI activity in each rolling 3 years, and keep a valid, unrestricted license.
DOs certified by the AOBR follow the AOA's Osteopathic Continuous Certification instead: 60 CME credits every 3 years, 15 of them self-assessment.
What usually overlaps
- Opioid course. An accredited opioid course that covers California's required content can count toward the opioid requirement and toward the general 50-hour total at the same time, when the activity awards the credit California accepts.
- Board CME. The ABR counts AMA PRA Category 1 credit. A Category 1 certificate can count toward your ABR total and toward California's hours at the same time; a Category 2 activity can only help on the state side, where the state accepts it. Check what credit each certificate awards.
- Federal MATE Act. If you hold a DEA registration, the one-time 8-hour training is federal and does not replace California's own rules. A MATE-qualifying accredited course will usually still count toward California's general total.
For radiologists in California
- Pain management and care of the terminally ill (including Schedule II addiction risk for post-2019 licensees): 12 hours, one-time (by 2nd renewal / within 4 years). Does not apply to radiologists: the page exempts pathologists and radiologists.
- Geriatric medicine / dementia: At least 20% of hours (about 10), per cycle while condition applies. Unlikely: the page limits this to internal medicine and family medicine physicians.
- Pace: California asks for 50 hours every 2 years, about 25 a year. The ABR asks for 75 credits in any rolling 3 years, about 25 a year. Certificates that carry credit both accept count toward each, so plan to the larger of the two.

Common questions
How many CME hours does California require for radiologists?
California's total is the same for physicians in every specialty: 50 hours every 2 years, plus 4 mandated topics, some limited to certain practices. Checked against the Medical Board of California's rules on October 13, 2026.
Does ABR CME count toward California's CME hours?
The ABR counts AMA PRA Category 1 credit. A Category 1 certificate can count toward your ABR total and toward California's hours at the same time; a Category 2 activity can only help on the state side, where the state accepts it. Check what credit each certificate awards.
