AAPC COC Certification Sample Questions

The AAPC Certified Outpatient Coder Certification Sample Question Set on this page is designed to familiarize you with the actual AAPC COC 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 Outpatient Coder (COC) 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 outpatient medical coders, facility coding professionals, ambulatory surgery center coders and related roles working in settings such as outpatient hospital departments, ambulatory surgery centers, hospital facility coding environments.

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 Outpatient Coder exam, particularly in areas such as outpatient facility coding, CPT®/HCPCS Level II/ICD-10-CM code assignment, payment methodology and compliance. You can use these sample questions as a starting point, then progress to the AAPC COC 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 COC Sample Questions:

01. A patient undergoes hospital outpatient hysteroscopy for postmenopausal bleeding. The operative report documents hysteroscopic visualization of the uterine cavity, removal of a small endometrial polyp with forceps, and endometrial sampling sent to pathology. The postoperative diagnosis is endometrial polyp with postmenopausal bleeding.

Refer to the outpatient surgery note above to answer question. Which coding approach best captures the encounter?
a) Report only the pathology examination because the final diagnosis depends on tissue review
b) Report abdominal hysterectomy because the uterus was evaluated and tissue was removed
c) Report diagnostic hysteroscopy only because forceps removal through the hysteroscope is not a therapeutic procedure
d) Report hysteroscopy with removal of the endometrial polyp and diagnosis coding for endometrial polyp and postmenopausal bleeding as supported by documentation

02. A 72-year-old Medicare patient presents for a scheduled diagnostic colonoscopy because of a positive fecal occult blood test. During the procedure, the physician advances the scope to the cecum, identifies a 6 mm sessile polyp in the transverse colon, and removes it completely by cold snare technique. The pathology report confirms a benign adenomatous polyp.

Refer to the hospital outpatient encounter note above to answer question. Which coding approach best captures the encounter?
a) Report a screening colonoscopy only because all Medicare colonoscopies begin as preventive services
b) Report the colonoscopy with snare removal and diagnosis coding for the positive fecal occult blood test and benign colon polyp as supported by documentation
c) Report a diagnostic colonoscopy without removal because cold snare removal does not count as polypectomy
d) Report only the pathology code because the final diagnosis came from the pathology report

03. An outpatient orthopedic note documents injection of the subacromial bursa for shoulder pain. Which anatomic location is most relevant to accurate code selection?
a) Lumbar spine
b) Wrist joint
c) Shoulder region
d) Hip region

04. An outpatient gastroenterology note documents ulcerative pancolitis without complications. The patient reports diarrhea related to the condition. Which ICD-10-CM coding approach is most appropriate?
a) Report ulcerative colitis with intestinal obstruction because diarrhea implies obstruction
b) Report ulcerative pancolitis without complications and do not separately report diarrhea when it is integral to the condition
c) Report diarrhea only because inflammatory bowel disease cannot be coded without inpatient admission
d) Report Crohn’s disease because all inflammatory bowel disease is coded the same way

05. A patient is treated in a hospital outpatient department for wound care. The facility claim is being prepared on a UB-04, and the physician’s professional service is billed separately. Which payment concept best explains why the hospital and physician may both bill for the same encounter?
a) The hospital outpatient department reports the facility resources, while the physician reports the professional work
b) The hospital and physician must combine all charges onto a single CMS-1500 claim
c) The UB-04 is used only for inpatient claims and cannot be used for outpatient services
d) The physician claim is prohibited whenever a hospital outpatient facility claim exists

06. A hospital outpatient operative note documents radiofrequency ablation of a liver tumor under imaging guidance. The report states that one hepatic lesion was ablated percutaneously, with no open incision. Which coding concept is most important?
a) Report only the malignancy diagnosis because ablation procedures are not coded
b) Code selection should reflect percutaneous tumor ablation, organ site, imaging guidance rules, and number of lesions when required
c) Report diagnostic liver biopsy because imaging guidance was used
d) Report open liver resection because tumor tissue was treated

07. A hospital outpatient department provides a service that is denied because prior authorization was required by the patient’s payer but was not obtained. Which payment-methodology concept is most relevant?
a) Payer-specific authorization requirements can affect claim payment even when the service is documented
b) Prior authorization is never required for hospital outpatient procedures
c) Prior authorization allows unsupported diagnoses to be added to the claim
d) Prior authorization changes an outpatient service into an inpatient admission

08. A hospital outpatient audiology report documents comprehensive audiometry threshold evaluation and speech recognition testing performed on the same date. Which documentation element most directly supports CPT® code selection?
a) The number of magazines in the waiting room
b) The patient’s preferred brand of hearing aid battery
c) The patient’s insurance deductible amount only
d) The specific audiologic tests performed and documented

09. A patient undergoes hospital outpatient percutaneous vertebral augmentation for a painful osteoporotic compression fracture of L2. The physician documents bilateral transpedicular needle access, cavity creation, cement injection into the L2 vertebral body, and fluoroscopic guidance. The postoperative diagnosis is age-related osteoporosis with current pathological fracture of the lumbar vertebra.

Refer to the outpatient operative note above to answer question. Which coding approach best captures the encounter?
a) Report routine epidural steroid injection because needles were placed near the spine
b) Report the percutaneous vertebral augmentation procedure for the lumbar vertebral level according to CPT® guidance and assign diagnosis coding for osteoporosis with current pathological lumbar fracture as documented
c) Report only low back pain because vertebral fracture coding requires inpatient admission
d) Report open spinal fusion because cement was injected into a vertebral body

10. A hospital outpatient radiology procedure note documents myelography to evaluate suspected spinal canal pathology. Which interpretation of myelography is most accurate for coding review?
a) Surgical removal of bone marrow from the pelvis
b) Visual examination of the urinary bladder
c) Imaging of the spinal cord or spinal canal after contrast introduction
d) Repair of a peripheral blood vessel
