O02 vs O31.0
O02 (Other abnormal products of conception) compared with O31.0 (Papyraceous fetus), 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. O02 carries an Excludes1 note covering O31.0: “papyraceous fetus (O31.0-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
