Z00.0Encounter for general adult medical examination

Z00.0 is the ICD-10-CM diagnosis code for encounter for general adult medical 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 (encounter for general examination without complaint, suspected or reported diagnosis), Z00.0 is specifically for encounter for general adult medical examination. Related codes cover newborn, infant and child health examinations (Z00.1), examination for period of rapid growth in childhood (Z00.2), examination for adolescent development state (Z00.3), examination of potential donor of organ and tissue (Z00.5), examination for normal comparison and control in clinical research program (Z00.6), examination for period of delayed growth in childhood (Z00.7) and other general examination (Z00.8).

To report this condition, pick the subcode that matches the documentation: Z00.00 (without abnormal findings) and Z00.01 (with abnormal findings).

Don't report Z00.0 together with the conditions in its Excludes1 note: encounter for examination of sign or symptom- code to sign or symptom and general health check-up of infant or child (Z00.12.-).

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