O00.11 vs O31.1
O00.11 (Tubal pregnancy with intrauterine pregnancy) compared with O31.1 (Continuing pregnancy after spontaneous abortion of one fetus or more), 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. O00.11 carries an Excludes1 note covering O31.1: “continuing pregnancy in multiple gestation after abortion of one fetus or more (O31.1-, O31.3-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
