Sample Certified Obstetrics Gynecology Coder Practice Questions
Try these questions from our free Certified Obstetrics Gynecology Coder practice tests. The correct answer and an explanation follow each question.
A gynecology coder queries a physician about an unspecified diagnosis code. Which element is required for a compliant physician query?
- A. The coder must suggest the preferred diagnosis to the physician
- B. The query must present all clinically reasonable options including 'clinically undetermined'
- C. Queries are only allowed before the claim is submitted
- D. The physician must respond within 24 hours or the code is dropped
Answer: B. The query must present all clinically reasonable options including 'clinically undetermined'
AHIMA and ACDIS guidelines require that queries offer all reasonable clinical options, including 'clinically undetermined,' to avoid leading the physician.
When a patient presents with a condition that is both an Excludes1 condition and integral to the reported condition, the coder should:
- A. Report both codes regardless of the Excludes1 instruction
- B. Report only the integral condition code
- C. Query the provider to confirm both conditions are distinct and documented, then follow the guideline
- D. Report only the Excludes1 code
Answer: C. Query the provider to confirm both conditions are distinct and documented, then follow the guideline
An Excludes1 note means the two conditions cannot occur together; if documentation suggests both are present, the coder should query the provider to clarify before coding.
Under CMS guidelines, which time threshold must be met to bill a 99215 office visit based on total time on the date of the encounter for an established gynecology patient?
- A. 30β39 minutes
- B. 40β54 minutes
- C. 55β69 minutes
- D. 20β29 minutes
Answer: B. 40β54 minutes
For 2021 and later E/M guidelines, 99215 requires 40β54 minutes of total time on the date of the encounter for an established patient.
A gynecologic surgical note states the surgeon 'explored the pelvis and found findings consistent with endometriosis.' A coder should:
- A. Code endometriosis as confirmed based on the surgeon's intraoperative description
- B. Query the physician because 'findings consistent with' is not a definitive diagnosis
- C. Code 'abnormal pelvic findings' only
- D. Leave the diagnosis code blank until pathology returns
Answer: A. Code endometriosis as confirmed based on the surgeon's intraoperative description
Intraoperative findings described by the surgeon during a procedure may be coded as confirmed diagnoses even before pathology confirmation, unlike outpatient suspected conditions.
