Z01.4 vs Z12.4
Z01.4 (Encounter for gynecological examination) compared with Z12.4 (Encounter for screening for malignant neoplasm of cervix), 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. Z12.4 carries an Excludes1 note covering Z01.4: “when screening is part of general gynecological examination (Z01.4-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
