About Z36.8

Z36.8 is the ICD-10-CM diagnosis code for encounter for other antenatal screening. It belongs to category Z36 (encounter for antenatal screening of mother), 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 10 subcodes must be used instead.

Within Z36, choose Z36.8 (other antenatal screening) only when documentation doesn't support a more specific option: antenatal screening for chromosomal anomalies (Z36.0), antenatal screening for raised alphafetoprotein level (Z36.1), other antenatal screening follow-up (Z36.2), antenatal screening for malformations (Z36.3), antenatal screening for fetal growth retardation (Z36.4), antenatal screening for isoimmunization (Z36.5) and antenatal screening, unspecified (Z36.9).

To report this condition, pick the subcode that matches the documentation: Z36.81 (fetalis), Z36.82 (translucency), Z36.83 (abnormalities), Z36.84 (maturity), Z36.85 (B), Z36.86 (length), Z36.87 (dates), Z36.88 (macrosomia) and 2 more.

It was added in FY2018, effective October 1, 2017.
