Question:
Patient seen for antepartum care but delivered at 38 weeks at a different hospital/physician group. What diagnosis codes should we use?
Answer:
The diagnosis coding for antepartum care would be specific to the patient’s condition at the time care was provided.
If the patient was having a routine pregnancy with no complications, you would choose a diagnosis code from the category Z34.-. If there were other conditions present, you would choose a code from Chapter 15 of the ICD-10 manual.
The American College of Obstetrics and Gynecology (ACOG) has two different guides that you might find helpful for more specific coding guidance in a particular case. Here are the links:
- ACOG Coding Guide: 2020 Diagnostic Coding in Obstetrics and Gynecology
- ACOG 2022 OB/GYN Coding Manual (which incorporates guidance from the 2020 Diagnostic Coding Guide)
