Z00.12Encounter for routine child health examination

Z00.12 is the ICD-10-CM diagnosis code for encounter for routine child health examination. It belongs to category Z00 (encounter for general examination without complaint, suspected or reported diagnosis), 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 2 subcodes must be used instead.

Within Z00.1 (encounter for newborn, infant and child health examinations), Z00.12 is specifically for encounter for routine child health examination. Related codes cover newborn health examination (Z00.11).

To report this condition, pick the subcode that matches the documentation: Z00.121 (with abnormal findings) and Z00.129 (without abnormal findings).

Don't report Z00.12 together with the conditions in its Excludes1 note: health check for child under 29 days old (Z00.11-), health supervision of foundling or other healthy infant or child (Z76.1-Z76.2) and newborn health examination (Z00.11-).

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