AAPC Obstetrics/Gynecology (COBGC) Examination Practice Test
Obstetrics and gynecology coding practice draws on reproductive anatomy, pregnancy care, and conditions affecting the female urinary and reproductive systems. The available questions sample clinical terms such as cervical intraepithelial neoplasia, endometriosis, urinary incontinence, preterm birth, and placenta previa, alongside diagnostic and treatment procedures used in gynecologic care.
Exam overview
About the AAPC Obstetrics/Gynecology (COBGC) Examination Exam
Strong coding decisions depend on distinguishing conditions with similar presentations and connecting clinical documentation to the correct diagnosis or procedure concept. Scenarios may ask you to identify urge incontinence from its symptom pattern, recognize a Bartholin gland infection by location, or distinguish placenta previa from other causes of bleeding during pregnancy. Procedure terminology also matters: colposcopy, cervical cone biopsy, and hysterosalpingography describe different examination or diagnostic purposes. Pregnancy questions can require interpreting gestational timing, while menopause questions may test the clinical rationale for adding progestogen to systemic estrogen when the uterus is intact. Practice these distinctions by identifying the decisive detail in each case—such as tissue location, cervical change, or the structure examined—before selecting an answer.
Sample Practice Questions
Review a selection from this exam's published US Practice Tests practice bank.
A cervical screening result shows abnormal cervical cells, and a biopsy confirms cervical intraepithelial neoplasia grade 3. Which description best characterizes this finding?
Show answer
Correct answer: BCIN 3 is a high-grade squamous intraepithelial lesion involving severe dysplasia or carcinoma in situ. By definition, it has not invaded the underlying cervical stroma.
A patient with an ovarian mass undergoes surgery, and pathology identifies endometrial-like tissue growing outside the uterus on the ovary. Which condition is characterized by endometrial tissue located outside the uterine cavity?
Show answer
Correct answer: BEndometriosis is the presence of endometrial-like tissue outside the uterine cavity. Adenomyosis, by contrast, involves endometrial tissue within the uterine muscle.
A patient reports leakage of small amounts of urine immediately after a sudden, compelling urge to void and before reaching the restroom. Which type of urinary incontinence best describes this pattern?
Show answer
Correct answer: BUrge incontinence is involuntary urine loss associated with a sudden, difficult-to-defer urge to urinate. Overflow incontinence is associated with incomplete bladder emptying, functional incontinence with barriers to reaching or using a toilet, and continuous incontinence involves persistent leakage.
A patient with an intact uterus is prescribed estrogen therapy for menopausal symptoms. Why is a progestogen commonly added to systemic estrogen therapy in this situation?
Show answer
Correct answer: AUnopposed systemic estrogen can stimulate the endometrium and increase the risk of endometrial hyperplasia and cancer. A progestogen is commonly used to provide endometrial protection when the uterus is present.
A patient develops a painful, fluctuant swelling near the vaginal opening at the lower posterior aspect of the labia. The clinician identifies an infected gland in this area. Which gland is most likely involved?
Show answer
Correct answer: BBartholin glands are located near the vaginal opening and can become obstructed or infected, producing a tender cyst or abscess. Skene glands are located near the urethral opening.
A pregnant patient at 34 weeks has regular contractions and cervical change. The newborn is delivered before 37 completed weeks of gestation. How is this birth classified by timing?
Show answer
Correct answer: BA birth occurring before 37 completed weeks of gestation is classified as preterm. Term begins at 37 completed weeks; post-term begins at 42 completed weeks.
A clinician performs an examination of the vagina and cervix using a speculum and a lighted magnifying instrument to evaluate an abnormal cervical screening result. What is this examination called?
Show answer
Correct answer: AColposcopy uses magnification and illumination to examine the cervix and vagina, often after an abnormal cervical screening result. Hysteroscopy examines the uterine cavity, while laparoscopy examines the abdominal and pelvic cavity.
How to use this practice test
The free practice bank contains 50 questions. Each session presents up to 20 questions selected at random and shows your results afterward. Use a session to check how well you distinguish gynecologic conditions, pregnancy findings, and procedure terms, then revisit any missed concepts in clinical references.
Preparation tips
- Compare urinary symptom patterns, especially urgency-related leakage versus leakage associated with physical exertion.
- Review cervical evaluation terminology, including colposcopy, biopsy, and excisional cone procedures; note each procedure’s purpose.
- Practice identifying pregnancy complications from the documented finding, such as placental position relative to the internal cervical os.
- Study reproductive anatomy and condition locations, including the Bartholin glands, ovaries, uterus, and fallopian tubes.
- Review how gestational age and cervical change distinguish preterm labor and birth from other pregnancy events.
