About Z13.4

Z13.4 is the ICD-10-CM diagnosis code for encounter for screening for certain developmental disorders in childhood. It belongs to category Z13 (encounter for screening for other diseases and disorders), block Z00-Z13 (persons encountering health services for examinations) 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 Z13 (encounter for screening for other diseases and disorders), Z13.4 is specifically for encounter for screening for certain developmental disorders in childhood. Related codes cover screening for diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism (Z13.0), screening for diabetes mellitus (Z13.1), screening for nutritional, metabolic and other endocrine disorders (Z13.2), screening examination for mental health and behavioral disorders (Z13.3), screening for eye and ear disorders (Z13.5), screening for cardiovascular disorders (Z13.6), screening for genetic and chromosomal anomalies (Z13.7), screening for other specified diseases and disorders (Z13.8) and 1 more.

To report this condition, pick the subcode that matches the documentation: Z13.40 (delays), Z13.41 (screening), Z13.42 ((milestones)) and Z13.49 (delays).

The conditions in its Excludes2 note aren't part of Z13.4, but may be coded alongside it if the patient has both: encounter for routine child health examination (Z00.12-).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2019 (expanded into subcodes).

Before ICD-10, this condition was coded in ICD-9-CM as V79.2 (special screening for intellectual disabilities), V79.3 (screening for developmental handicaps in early childhood) and V79.8 (screening for other specified mental disorders and developmental handicaps).
