The case list advantage.
Built into your workflow from day one.
The oral certifying examination is built from your submitted case list. The physician who documents strategically from July 1 walks in with an edge no review course can replicate. PDI Med is the first scalable oral board infrastructure built for the board-eligible OB/GYN — not a study tool, not a checklist, but a system that reads your cases the way an examiner does, starting the day you commit your first encounter.
The exam is your case list.
Each 1-hour session (OB, GYN, Office) is divided into two halves. The first 30 minutes: standardized scenarios written by ABOG examiners — same for every candidate. The second 30 minutes: questions built exclusively from your submitted case list. The examiner has read your cases before you walk in. They have selected which ones to probe. Every case you submitted is fair game.
Three sections. Three sets of rules. Zero ambiguity.
These are the case requirements per the 2027 ABOG Specialty Certifying Examination Bulletin. They are separate from the category lists, which ABOG publishes on its website rather than in the bulletin. PDI Med monitors ABOG bulletins and updates this page when requirements change — you don't have to track it separately.
- Gestational age at admission (not at delivery)
- Delivery type
- Complication documented
- Nights in hospital
- Pre-operative and post-operative diagnosis
- Procedure(s) performed and surgical route
- Uterine weight in grams (all hysterectomies)
- Cyst diameter in cm (all ovarian cases)
- Number of office visits for this case
- Primary diagnosis
- Management plan summary
Every deadline is hard. There are no extensions.
Dates below are the 2027 certifying examination cycle. PDI Med tracks ABOG deadline changes — this page is updated when the bulletin changes. Missing the case list submission cutoff means waiting a full year to sit for boards.
The category structure ABOG publishes.
The Specialty Certifying Examination Bulletin sets the case requirements — it does not enumerate the categories. ABOG publishes those separately on its website: currently 30 in Obstetrics, 32 in Gynecology, and 39 in Office Practice. The headings below are drawn from those published lists; ABOG's own posting is authoritative and takes precedence over this page. PDI Med maps every case you commit to a category. No more than two cases per category count toward the minimum. Uncategorized entries do not count at all.

every complicated case · at least 20Gynecology (GYN)
every surgical case · at least 20Office
exactly 40 casesThe 2027 Specialty Certifying Examination Bulletin issued in June 2026 and governs the cycle described on this page. The categories are published separately on ABOG's website and can change between bulletins — some topics currently grouped under a broader heading may become standalone categories, which is worth watching through 2027. When ABOG revises the lists, PDI Med diffs them, updates the platform, and publishes a changelog here.
Where examiners are going.
Synthesized from America's Board Review tip archives (Aug 2024 – Mar 2025) and physician experience reporting. Relative frequency reflects examiner emphasis, not pass/fail risk.
The shift examiners are watching — and probing.
Robotic hysterectomy has expanded significantly over the last decade. Vaginal hysterectomy rates have declined. Examiners are acutely aware of this shift — route selection justification is one of the most reliably probed decision points in the GYN session. [ABR Mar 2025]
The 8 most common case list mistakes — and how PDI Med catches them.
Synthesized from the ABOG Specialty Certifying Examination Bulletin (2027 edition, issued June 2026), America's Board Review archives (2024–2025), and physician experience from SDN and ABOG forums.
ABOG requires uterine weight in grams from the pathology report for every hysterectomy case — no exceptions. Physicians discover this missing field months after the operation when the chart is difficult to retrieve and pathology results may have been archived. ABOG rejects the case without it.
Office must be exactly 40 cases. Not 38 — not 42. Physicians consistently over- or under-submit here, discovering the error during the export attempt in the days before the August 31 cutoff.
Cases accumulate naturally — you see what you see. End up with 3 preeclampsia cases, 3 hysterectomies, 3 LEEPs. Only two per category count toward the section minimum, so the physician submits thinking they have 80 credited cases when ABOG credits 77. Listing all of them is still correct: ABOG requires every GYN surgical patient and every complicated OB patient you primarily cared for to be listed, and omitting one is the far more serious error.
Uncomplicated vaginal deliveries and routine repeat cesareans are explicitly ineligible for OB. New attendings frequently assume any delivery counts. Every OB case must document the specific complication — preeclampsia, shoulder dystocia, fetal distress, abruption, etc.
GA at admission is required — distinct from gestational age at delivery. This field is commonly omitted when logging and nearly impossible to retrieve retroactively from an 8-month-old operative or delivery note. It is a required ABOG field, not optional.
Cases documented as "c-section" or "hysterectomy" without specifics invite aggressive examiner follow-up on areas the physician may not be prepared to defend. The examiner reads exactly what you wrote. Vague entries signal incomplete reasoning — not safety. "Case construction is a painful process — the ABOG is very vague." [SDN]
Physicians collect what they happen to see in their practice. Without strategic awareness, they end up with no urogyn cases, no vaginal hysterectomy, no oncology management — all high-yield examiner topics. If those case types are absent, prepare to defend why with the cases you do have. [ABR Mar 2025]
Memory degrades. Required fields become impossible to retrieve from operative notes 6 months later. Physicians who batch-log in February face unrecoverable deficits and chart review weekends that don't actually recover what they've lost. Missing the August 31 cutoff means waiting a full year.
Common misconceptions — and what's actually true.
What PDI Med builds for you — automatically.
Every feature below exists because a physician somewhere lost a year to a preventable mistake. PDI Med is the system that prevents it.
Where PDI Med fits — and where it's going.
If you are collecting cases, the qualifying exam is already behind you. By the time you are an attending documenting your first clinical year, that prerequisite is done. FLS or EMIGS — either one satisfies it — is documented with your ABOG application, and eligibility is ABOG's determination, not ours; PDI Med gates nothing on it. What isn't done — and what nothing else adequately addresses — is everything below.
The first 30 minutes of each oral board session uses ABOG-written structured cases — not your case list. Preparing for that half still requires a dedicated board review course: America's Board Review, ExamPro, or an equivalent. PDI Med covers the documentation layer and the compliance layer today; the case-specific prep layer arrives with the AI Board Examiner, expected December–January. The structured case half is where a board review course remains essential today, and we say so plainly.
The structured case library is on the roadmap. Until it is built, the combination that produces the best outcome is PDI Med for everything case-list-related, paired with a structured case course for the remaining half.
PDI Med eliminates the documentation burden — hours per week reduced to minutes per case — and ensures compliance. With the AI Board Examiner, expected December–January, it will prepare you for exactly half the oral board examination. That half is the one built from your cases. That half is the one most physicians are least prepared for.
The physician who walks into the exam with a bulletproof case list and a rehearsed defense of every case on it has done the work that PDI Med exists to make possible. Add a structured case course for the first half, and the preparation is complete. The documentation is handled. The compliance is handled. The case-specific intelligence is on the way. What's left is studying — and that is a much better problem to have.
We don't replace the board review course.
We make everything you bring to it count.
