O00 vs O20
O00 (Ectopic pregnancy) compared with O20 (Hemorrhage in early 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. O20 carries an Excludes1 note covering O00: “pregnancy with abortive outcome (O00-O08)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
