CDEO exam-day guide
CDEO · Prepare for the day ahead.
Your checklist
Government-issued photo ID
Bring the exact name-matching photo ID the provider requires. Name on the ID should match the name on your registration; if it does not, contact the provider before test day to correct it.
Exam appointment confirmation / authorization to test
Print or save the confirmation email or scheduling notice with your test date, time, location or online proctoring link, and any candidate ID number.
Approved code manuals (if the exam is open-book)
CDEO-style exams are commonly open-book with current ICD-10-CM, CPT, and HCPCS Level II manuals permitted, but binding, tabbing, and annotation rules vary. Confirm the exact open-book and manual-allowed policy with the provider and follow it precisely (needs_review).
Short, tabbed reference notes inside permitted manuals only
Use index tabs and handwritten or highlighted notes only if the provider permits annotations. Loose papers, sticky notes with writing, and separate study sheets are usually prohibited; verify (needs_review).
Two or more No. 2 pencils and a soft eraser (paper-based sitting)
Some sittings are paper-and-pencil and require pencils; others are computer-based and provide scratch materials. Confirm which format applies to you (needs_review).
Simple, silent items only - no smart devices
Leave smartwatches, fitness bands, phones, and earbuds at home or in the provided locker. Many providers prohibit these in the testing room entirely.
Comfort items permitted by the provider
Layers, water in a clear container, and tissues are often allowed but rules differ by site. Ask in advance rather than assuming (needs_review).
Plan for food, medication, and restroom needs
Eat a normal meal beforehand, bring any necessary medication in its original container (declare it to the proctor), and plan around scheduled breaks. Confirm the break policy in advance.
Directions, parking, and arrival buffer
Confirm the address or proctoring link the day before and arrive with a buffer well beyond the provider's stated check-in time. For remote proctoring, test your camera, microphone, and internet connection ahead of time.
Pace plan written down and memorized
Divide the total question count by the total minutes to get a per-question target, and note the halfway checkpoint time so you can adjust speed during the exam.
Scratch-paper strategy (if permitted)
Plan to jot only key facts for long documentation scenarios - setting, provider type, diagnoses, procedures, and query opportunity. Use only the materials the proctor supplies (needs_review).
Questions to ask the provider before test day
Write out anything unresolved - open-book policy, break rules, scoring and retake policy, score report timing - and get written answers before you sit.
Plan the day
Stop learning new content. Review high-yield frameworks instead: documentation elements required for E/M level selection, medical necessity linkage between diagnosis and service, query-writing best practices, and the compliance and auditing concepts you consistently miss. Re-read your own error log.
Confirm logistics in writing: test location or proctoring link, start time, arrival or check-in window, what is allowed in the room, and ID requirements. Resolve any open questions with the provider now, not on test day.
Do one timed practice set under exam conditions - full silence, no pauses, permitted references only - so you can validate your pacing plan and identify time sinks.
Do a light review only: tab placement in permitted manuals (if open-book), a short pass over guideline highlights, and your pacing plan. No new question banks and no cramming after early evening.
Pack your bag: ID, confirmation, permitted manuals and approved tabs, pencils if required, comfort items, and any medication. Lay out clothing and confirm transportation or test your remote setup end to end.
Protect sleep. Set two alarms, avoid alcohol, and get to bed at your normal time. Fatigue costs more points than one extra hour of review gains.
Eat a normal meal and hydrate moderately. Arrive with a large buffer - aim to be at the site or logged in well before the check-in window opens. Rushing is the most common cause of a bad start.
Answer every question you can decide confidently, flag the rest, and move on. Never leave a question blank. Use the documentation scenario to locate the key facts before looking at the answer options.
Check your halfway checkpoint against the expected time. If you are behind, shorten time on short recall items and protect time for long documentation scenarios, which carry the same point value.
Return to flagged items and work them by elimination. For documentation questions, ask: is the element documented, is it linkable to medical necessity, and does the code choice match what the record actually supports?
If breaks are permitted, take them at planned points rather than mid-scenario. Stand, stretch, and reset your attention; confirm whether the clock stops during breaks before you decide how long to take (needs_review).
Note what felt difficult while it is fresh, then stop reviewing content. Confirm with the provider how and when results are released and what the retake policy is, in case you need it.
Rules to check
Bring valid, unexpired photo ID with a name that matches your registration exactly. If your legal name differs from your registration, fix it with the provider before test day - do not expect a site-level exception.
Follow the provider's permitted-materials policy literally. Assume nothing is allowed into the testing room except what is explicitly listed; unapproved notes, loose papers, or devices can void your sitting.
All electronic devices must be off, out of reach, and preferably left at home or in the provided storage. A device that vibrates or lights up during the exam can be treated as a conduct violation.
Do not communicate with other candidates during the exam - no talking, gesturing, or sharing materials. Read the confidentiality and non-disclosure agreement carefully; reproducing exam content afterward is prohibited.
Answer every question. Unanswered questions are scored as incorrect, and long documentation scenarios are worth the same as short recall items, so budget time accordingly.
Use breaks only as the provider permits. Confirm in advance whether the timer pauses, whether you can access notes or manuals during a break, and whether leaving the room ends your session (needs_review).
Scoring, passing thresholds, score reporting timelines, and retake or appeal procedures are set by the certifying body - confirm each of these with the provider before test day rather than relying on secondhand information (needs_review).
If a technical problem, distraction, or proctor instruction conflicts with your plan, stop and notify the proctor immediately and ask for the issue to be documented. Do not attempt to troubleshoot or continue around a disrupted session on your own.
