Z34.8Encounter for supervision of other normal pregnancy

Z34.8 is the ICD-10-CM diagnosis code for encounter for supervision of other normal 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, choose Z34.8 (other normal pregnancy) only when documentation doesn't support a more specific option: normal first pregnancy (Z34.0) and unspecified (Z34.9).

To report this condition, pick the subcode that matches the documentation: Z34.80 (unspecified trimester), Z34.81 (first trimester), Z34.82 (second trimester) and Z34.83 (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.
