A prenatal visit for a patient with a normal pregnancy in the second trimester would be coded as which ICD-10-CM code?

• A. Z34.01
• B. Z34.02
• C. Z34.3
• D. Z34.00

Answer: (B)

For prenatal visits when the pregnancy is normal, use the Z34 category that indicates supervision of a normal pregnancy, with the trimester specified by the ending digits. The digits after Z34 denote the trimester: .01 for first trimester, .02 for second, .03 for third, and .00 when the trimester isn’t specified. Since this visit occurs in the second trimester, the correct code is Z34.02. Other endings would point to first trimester or unspecified/other scenarios, which don’t match a second-trimester normal-pregnancy encounter. This approach applies specifically to routine prenatal care with no complications; different codes are used if there are complications or high-risk factors.
