N70 vs O23

N70 (Salpingitis and oophoritis) compared with O23 (Infections of genitourinary tract in 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. N70 carries an Excludes1 note covering O23: “pregnancy, childbirth and the puerperium (O23.-, O75.3, O85, O86.-)”

Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
