Which ICD-10-CM code describes supervision of a normal first pregnancy in the second trimester?

• A. Z34.02
• B. Z34.00
• C. Z33.2
• D. Z34.9

Answer: (A)

Supervision of a normal pregnancy uses the Z34 category, with the decimal digit indicating the trimester. The second-trimester code is the one that matches a routine prenatal visit during the second trimester, regardless of whether it’s a first pregnancy. In this case, the patient is a normal pregnancy in the second trimester, so the appropriate code is the second-trimester supervision code. That’s why this option is correct: it specifies supervision of a normal pregnancy in the second trimester. The other codes either refer to different trimesters (first or third, or unspecified) or to a pregnancy state that isn’t routine supervision. The notion of the pregnancy being the first one is captured in clinical notes (gravida) but not encoded in this Z34 code itself.
