Written on Z01 — Encounter for other special examination without complaint, suspected or reported diagnosis

encounter for examination for administrative purposes (Z02.-)
encounter for examination for suspected conditions, proven not to exist (Z03.-)
encounter for laboratory, radiologic and imaging examinations for sign(s) and symptom(s) - code to the sign(s) or symptom(s)

Excludes2 inherited from the categories above Z01.1

Also inherited, and the opposite of Excludes1: these conditions are not part of Z01.1, but a patient can have both, so you may code both.

screening examinations (Z11-Z13)

Z01.1 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Z01.1 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
