Z01 vs Z02

Z01 (Encounter for other special examination without complaint, suspected or reported diagnosis) compared with Z02 (Encounter for administrative examination), from the official CMS tabular data. Do not report these codes together: the official tabular list marks them Excludes1.

Can these codes be reported together?

No — do not report together. Z01 carries an Excludes1 note covering Z02: “encounter for examination for administrative purposes (Z02.-)”

Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
