COBGC Evaluation and Management Coding 1 — Questions and Answers
Question 1: What are the key components of E/M coding for OB/GYN visits?
- History, examination, and medical decision-making complexity (Correct answer)
- Only the diagnosis
- Only the time spent
- Only the procedures performed
Correct answer: History, examination, and medical decision-making complexity
E/M code selection is based on the extent of history taken, examination performed, and complexity of medical decision-making.
Question 2: How is time-based E/M coding used in OB/GYN?
- When counseling or coordination of care dominates the visit, total time determines the code level (Correct answer)
- Time is never a factor
- Only surgical time counts
- Time-based coding is not allowed in OB/GYN
Correct answer: When counseling or coordination of care dominates the visit, total time determines the code level
When more than 50% of the visit involves counseling/coordination, time can determine the E/M level instead of the three key components.
Question 3: What is the difference between new and established patient E/M codes?
- New patients have not been seen by the practice within 3 years; established patients have (Correct answer)
- All patients are new
- Only the first visit is a new patient visit
- The distinction does not affect coding
Correct answer: New patients have not been seen by the practice within 3 years; established patients have
New patient codes (99201-99205) have higher values than established patient codes (99211-99215) because they require more comprehensive evaluation.
Question 4: What documentation supports medical necessity for E/M services?
- Chief complaint, history of present illness, review of systems, and clinical findings supporting the diagnosis (Correct answer)
- Only the diagnosis code
- Only the patient's name
- A brief note is sufficient
Correct answer: Chief complaint, history of present illness, review of systems, and clinical findings supporting the diagnosis
Thorough documentation of the clinical encounter supports the medical necessity of the service level billed.
Question 5: How are preventive visit codes used in gynecology?
- For annual well-woman exams including breast and pelvic examinations, separate from problem-oriented visits (Correct answer)
- They replace all other codes
- Preventive codes are not used in gynecology
- Only for patients under 40
Correct answer: For annual well-woman exams including breast and pelvic examinations, separate from problem-oriented visits
Preventive visit codes cover routine wellness exams; if a problem is also addressed, a separate E/M code with modifier 25 may be added.
Question 6: What is modifier 25 and when is it used?
- A significant, separately identifiable E/M service on the same day as a procedure (Correct answer)
- A discount modifier
- Used for follow-up visits only
- Applied to all E/M codes automatically
Correct answer: A significant, separately identifiable E/M service on the same day as a procedure
Modifier 25 indicates that a separate E/M service beyond the procedure was necessary and documented on the same day.
