O36.4 vs Z33.2
O36.4 (Maternal care for intrauterine death) compared with Z33.2 (Encounter for elective termination of pregnancy), 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. Z33.2 carries an Excludes1 note covering O36.4: “late fetal death (O36.4)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
