Z34.0Encounter for supervision of normal first pregnancy

Z34.0 is the ICD-10-CM diagnosis code for encounter for supervision of normal first pregnancy. It belongs to category Z34 (encounter for supervision of normal pregnancy), block Z30-Z39 (persons encountering health services in circumstances related to reproduction) and chapter 21 (factors influencing health status and contact with health services). It is a header code, so it can't be reported by itself; one of its 4 subcodes must be used instead.

Within Z34 (encounter for supervision of normal pregnancy), Z34.0 is specifically for encounter for supervision of normal first pregnancy. Related codes cover other normal pregnancy (Z34.8) and unspecified (Z34.9).

To report this condition, pick the subcode that matches the documentation: Z34.00 (unspecified trimester), Z34.01 (first trimester), Z34.02 (second trimester) and Z34.03 (third trimester).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
