N83.6 vs O00.1
N83.6 (Hematosalpinx) compared with O00.1 (Tubal 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. N83.6 carries an Excludes1 note covering O00.1: “tubal pregnancy (O00.1-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
