AAPC CDEO Certification Sample Questions

The AAPC Certified Documentation Expert Outpatient Certification Sample Question Set on this page is designed to familiarize you with the actual AAPC CDEO exam format and question types. These sample questions help you understand how questions are structured and what to expect on test day. While they provide a useful starting point, they represent only a limited preview of the real exam experience.

These sample questions are intended for evaluation and familiarization only. To understand exam style, pacing, and reasoning patterns more clearly, we recommend trying our online sample practice environment. If you are preparing for the AAPC Certified Documentation Expert Outpatient (CDEO) and want to assess your readiness more rigorously, structured, timed, scenario-based practice is recommended. This approach aligns with the cognitive demands and professional expectations typically associated with clinical documentation professionals, medical coding professionals, coding auditors and related roles working in settings such as outpatient provider practices, ambulatory care organizations, healthcare revenue cycle departments and related settings.

The demo introduces core concepts, while full-length premium simulations provide deeper, scenario-based coverage that more closely reflects the actual cognitive demands of the AAPC Certified Documentation Expert Outpatient exam, particularly in areas such as outpatient documentation review, documentation improvement communication, CPT®/ICD-10-CM/HCPCS Level II coding accuracy. You can use these sample questions as a starting point, then progress to the AAPC CDEO Certification Practice Exam for stronger readiness. Our premium simulations are designed to mirror real exam conditions, helping you refine reasoning, pacing, and decision-making before your official exam attempt.

AAPC CDEO Sample Questions:

01. A CDI specialist notices that a provider frequently responds to queries by copying the CDI specialist’s wording into the note without adding clinical reasoning. Which follow-up is most appropriate?
a) Educate the provider that the final documentation should reflect the provider’s own clinical assessment and supported diagnosis
b) Continue the practice because copied CDI language is efficient and creates consistent wording
c) Ask CDI staff to write longer suggested diagnoses so providers can copy them more completely
d) Tell coders to treat copied CDI wording as invalid even when the provider signs the note

02. An established patient presents with stable hypothyroidism and new chest discomfort. The provider reviews prior cardiology records, orders an ECG and troponin, discusses emergency precautions, and refers the patient for same-day cardiology evaluation. Which E/M element is most relevant to risk?
a) Stable hypothyroidism alone because it is a chronic condition
b) Decision-making related to possible serious cardiac symptoms and urgent referral precautions
c) The fact that the patient is established rather than new
d) The patient’s normal thyroid medication refill history

03. A 64-year-old patient is seen in a wound clinic for a right medial ankle ulcer. The provider documents: “Chronic leg wound, improving. Compression continued. Measurements 2.1 cm × 1.4 cm. Fat layer visible.” The vascular study from the prior month showed venous reflux, but the provider does not document venous stasis ulcer, pressure ulcer, diabetic ulcer, laterality in the assessment, or ulcer severity.
Refer to the shared case documentation above. Which CDI action is most appropriate before final coding?
a) Assign the most severe ulcer code because fat layer is visible
b) Report only venous reflux because the provider did not use the word ulcer
c) Code bilateral leg ulcers because venous disease commonly affects both legs
d) Query the provider using the documented wound location, measurements, visible fat layer, venous reflux history, and compression treatment

04. A physician practice is transitioning from a primarily fee-for-service model to a value-based contract that includes quality performance and risk adjustment. Which documentation change is most important for CDI to support?
a) Clear documentation of active conditions, severity, treatment status, and quality-measure elements
b) Copying all historical diagnoses forward so the payer sees the patient as complex
c) Shorter notes that list only the procedure performed to reduce audit exposure
d) Documentation focused only on services with the highest CPT® payment rate

05. An EHR problem list includes “heart failure, CKD, COPD, diabetes, anemia, depression, obesity, and peripheral vascular disease.” In today’s note, the provider addresses only diabetes medication adjustment and foot numbness. Which CDI concern is most appropriate?
a) None of the problem-list diagnoses can ever be coded because they are not in the chief complaint
b) All problem-list diagnoses should be coded because the provider opened the chart
c) The coder should select only the diagnosis with the highest risk score from the problem list
d) The problem list may create note bloat if conditions are carried forward without current relevance or management

06. An outpatient cardiology group begins a CDI initiative after discovering frequent nonspecific diagnosis reporting on claims and inconsistent documentation of disease severity. A physician says, “If the coder can see what I meant, the note should be enough.” Which CDI goal is most appropriate to emphasize?
a) Complete documentation should clearly support the clinical condition, severity, and services reported
b) Documentation improvement should be limited to procedures with high reimbursement value
c) CDI should focus only on claims that have already been denied by the payer
d) Coder interpretation should replace provider clarification when the clinical picture seems obvious

07. A 61-year-old patient is seen in an outpatient oncology clinic. The provider documents: “Colon cancer status post colectomy 2 years ago. Completed chemotherapy 18 months ago. New CT shows two liver lesions suspicious for metastases. Biopsy scheduled. Patient anxious. Continue surveillance.” The assessment lists “history of colon cancer” and “liver lesions.” No metastatic disease is diagnosed.
Refer to the shared case documentation above. Which diagnosis coding approach is most appropriate based on the current documentation?
a) Report metastatic colon cancer because the CT describes suspicious liver lesions
b) Omit all oncology-related diagnoses because biopsy has not yet been performed
c) Report active colon cancer because chemotherapy was completed 18 months ago
d) Report the documented history of colon cancer and liver lesions or findings as supported, but do not report metastases unless diagnosed by the provider

08. A pediatric note documents “heart murmur, likely congenital” after a newborn exam. No echocardiogram has been completed, and the provider orders cardiology evaluation. Which CDI concern is most appropriate?
a) The murmur should be ignored because congenital conditions cannot be coded in outpatient visits
b) The coder should report an acquired valvular disorder because all murmurs are acquired after birth
c) The record should clarify whether a congenital condition has been confirmed or whether the murmur is still under evaluation
d) The coder should report a congenital heart defect because the provider used the word likely

09. A cardiology note states: “Atrial fibrillation, paroxysmal, on apixaban. No palpitations today. Continue anticoagulation.” Which diagnosis coding principle is most appropriate?
a) Report history of atrial fibrillation because the rhythm is not symptomatic today
b) Report paroxysmal atrial fibrillation as an active condition because it is documented and managed
c) Report chronic atrial fibrillation because anticoagulation is continued
d) Omit atrial fibrillation because the patient has no palpitations today

10. A neurology note states: “Seizure disorder controlled on levetiracetam. No seizures in 18 months. Continue medication; no driving restrictions changed.” Which documentation feature best supports reporting epilepsy as an active condition?
a) The fact that the patient has no current neurologic symptoms
b) The absence of a seizure during today’s visit
c) Ongoing provider assessment and continued antiepileptic medication management
d) A childhood febrile seizure listed in family history
