The CDIP is 140 questions in three hours, and only 106 of them count. The other 34 are pretest items AHIMA is trialing for future forms, scattered randomly, and nothing on screen tells you which is which. That is roughly 77 seconds per question, which is comfortable for a recall item and tight for a long clinical vignette followed by four plausible query options.
Most items ask what a CDI professional should do next, or what the record supports. They are not definition checks. You read a scenario, decide whether the documentation is complete, conflicting or clinically unsupported, and pick the compliant response. You can move back and forth and flag items, but only for questions you have already answered.
Detail | What AHIMA publishes |
|---|---|
Questions | 140 (106 scored, 34 pretest) |
Time | 3 hours |
Passing score | 300 (published as a score, not a percentage correct) |
Delivery | Pearson VUE test center, or OnVUE online proctoring for candidates in the United States |
Fee | $259 for AHIMA members, $329 for non-members; retakes cost the same |
Retake wait | 90 days, with a new application |
First-time pass rate | 68% in 2025 (591 candidates), 68% in 2024 (433), 65% in 2023 (412) |
Those pass rates cover first-time candidates only. Roughly one in three people who sit the exam for the first time don't pass, so treat it as a serious exam even though the credential pool is small (2,913 certified professionals at the end of 2025).
The current content outline took effect on June 1, 2023, and it splits the exam into five domains.
Domain | Weight | What it tests in practice |
|---|---|---|
1. Clinical Coding Practice | 15–18% | Principal vs. secondary diagnosis, code sequencing, working vs. final DRG, resolving discrepancies with coders |
2. Education and Leadership Development | 21–26% | Physician champions, CDI policies, query documentation rules, chain of command for unanswered queries, teaching different audiences |
3. Record Review & Document Clarification | 27–33% | Reading the chart, spotting gaps, query development, POA, acuity and chronicity, complications, post-discharge queries |
4. CDI Metrics & Statistics | 8–11% | Dashboards, physician benchmarking, external benchmarks, query response trends, quality audits |
5. Compliance | 18–23% | Ethical practice, clinical validation queries, second-level reviews, non-compliant queries, query retention, technology risk |
Domain 3 alone is more than a quarter of the exam. Domains 2 and 5 together are roughly 39–49%, and most people don't budget that much time for them. If your study plan is mostly coding and DRGs, it doesn't match where the points sit.
Domain 2 is not soft. Nurses and coders both tend to skim it because it sounds like management theory. The tasks are concrete: what belongs in a facility policy on query documentation, who you escalate to when a provider never answers, how you'd teach a hospitalist group differently from a coding team, and how documentation quality reaches research, public health reporting and case management. Expect situational questions where two answers are both sensible and only one follows proper channels.
Compliance is the domain that punishes instinct. Experienced CDI staff often lose points by choosing the answer that would get the diagnosis documented fastest. The exam favors the answer that keeps the query non-leading, supported by clinical indicators and defensible. Know when a clinical validation query is appropriate, when a second-level review is warranted, and what makes a query non-compliant.
The query practice brief has just been rewritten. AHIMA and ACDIS released a 2026 update to Guidelines for Achieving a Compliant Query Practice on September 1, 2026, and it supersedes the 2022 version. The content outline predates it, and I haven't seen AHIMA say how quickly exam items reflect the new text. Read the current brief, which is free on the ACDIS website, and be careful with older study notes that quote the 2022 wording.
Clinical depth hits coders hardest. AHIMA recommends background in medical terminology, anatomy and physiology, pathology and pharmacology, and Domain 3 is where that gap shows. If you code well but can't say why a lactate trend or a drop in ejection fraction changes what a query should ask, that's where you'll lose points.
Coding conventions hit nurses hardest. The mirror-image weakness: strong clinical judgment, but shaky on principal diagnosis selection, sequencing rules and how a working DRG changes to a final one.
Domain 4 looks small and still costs people. At 8–11%, it's tempting to skip. But the tasks include interpreting physician benchmarking data and comparing your institution against outside benchmarks, and a few missed items here matter against a scaled cut score.
The most useful thing you can do after a wrong answer is label why you missed it. For the CDIP, misses tend to fall into three buckets: a clinical gap, a coding-convention gap, or a compliance-judgment gap. Keep a running tally. If most of your misses sit in one bucket, more sets won't fix it; go back to the source for that domain.
A few habits that fit this exam specifically:
Read the scenario before the options. Decide what the record supports, then look for the answer that matches your conclusion. Reading options first invites you to argue for whichever sounds most familiar.
Practice the timing honestly. The 50-question sets here run 50 minutes, about a minute per item, which is a little tighter than the 77 seconds you'll have on exam day. That's useful pressure. Do at least two or three back to back in the last weeks so a three-hour session doesn't feel new.
Explain your wrong choices. For every item you miss, be able to say why the option you picked was non-compliant, unsupported or out of scope, not just why the right one was right.
Don't memorize the bank. With more than 1,000 questions, some repeat recall is inevitable. Space out retries by several days and check that you can defend the answer, not recognize it.
AHIMA doesn't disclose its exam questions, so no practice set reproduces the actual test. Use practice results to find weak domains, not as a prediction of your score.
A miss costs at least the exam fee again plus a 90-day wait, so the avoidable errors are worth knowing.
Preparing for it as a coding exam. Coding is 15–18% of the outline; judgment about records, queries and compliance is the rest.
Choosing the answer that would maximize documentation capture rather than the one that is compliant.
Booking too early. You must schedule within 120 days of eligibility approval, so apply when your study plan is nearly done, not at the start of it.
Spiraling over odd-looking items. About one question in four is unscored, and you can't tell which. Flag it, make your best call and move on.
Relying on older notes. Some earlier guides call the credential "Documentation Improvement Practitioner," and their query guidance may pre-date the 2026 brief.
These are my suggestions, not AHIMA's. Adjust for how many hours a week you have.
Meets the degree or credential requirement but new to CDI (about 12–16 weeks). AHIMA recommends about two years of CDI experience, and without it you're learning the job and the exam at once. Spend the first month on clinical foundations and coding conventions, the middle on record review and queries, and the last four to five weeks on timed sets and compliance.
Working CDI nurse or physician (about 6–8 weeks). Your clinical side is strong. Put early time into coding conventions, DRG logic and the metrics domain, then move quickly to compliance and Domain 2, where clinical people are most often surprised.
Experienced coder moving into CDI (about 8–10 weeks). Coding will feel familiar. Spend your time on clinical indicators, query construction and the compliance guidance.
Retaking (about 4–6 weeks of focused work). Use your score report to find which domains cost you, then rebuild them from source. The 90-day wait gives you room, so don't spend it re-doing the sets you already scored well on.
Two things are worth knowing. The exam's content outline dates from June 2023, following a job task analysis that began in 2022 and a pilot exam in June 2023. And the compliant query guidance was rewritten in September 2026 (covered above). AHIMA may publish a newer outline down the line, so confirm the current version on its CDIP page before finalizing your study plan.Want to test your knowledge on another certification?

Many CDI job postings accept either the AHIMA CDIP or the ACDIS CCDS (and CCDS-O for outpatient). Which one carries more weight varies by employer and region, so check postings in your market before deciding. CDIP is open to nurses, physicians and health information professionals who hold an associate's degree or higher, or a CCS, CCS-P, RHIT or RHIA credential.
This page links to 10 CDIP practice exams with more than 1,000 questions in total. The listed test is 50 questions in 50 minutes, sessions are timed, every question has an explanation, and your results are tracked so you can see which areas are slipping.
