Z01Encounter for other special examination without complaint, suspected or reported diagnosis

Z01 is the ICD-10-CM diagnosis code for encounter for other special examination without complaint, suspected or reported diagnosis. It belongs to 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 6 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: Z01.0 (vision), Z01.1 (hearing), Z01.2 (cleaning), Z01.3 (pressure), Z01.4 (examination) and Z01.8 (examinations).

Don't report Z01 together with the conditions in its Excludes1 note: encounter for examination for administrative purposes (Z02.-), encounter for examination for suspected conditions, proven not to exist (Z03.-) and encounter for laboratory, radiologic and imaging examinations for sign(s) and symptom(s) - code to the sign(s) or symptom(s).

The conditions in its Excludes2 note aren't part of Z01, but may be coded alongside it if the patient has both: encounter for laboratory and radiologic examinations as a component of general medical examinations (Z00.0-) and screening examinations (Z11-Z13).

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