About coding prenatal care only pregnancy
The ICD-10-CM code for prenatal care only pregnancy is Z34.9 (Encounter for supervision of normal pregnancy, unspecified). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on Z34.9.
Within Z34, choose Z34.9 (unspecified) only when documentation doesn't support a more specific option: normal first pregnancy (Z34.0) and other normal pregnancy (Z34.8).
To report this condition, pick the subcode that matches the documentation: Z34.90 (unspecified trimester), Z34.91 (first trimester), Z34.92 (second trimester) and Z34.93 (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.
