E29 vs N46.0

E29 (Testicular dysfunction) compared with N46.0 (Azoospermia), 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. E29 carries an Excludes1 note covering N46.0: “azoospermia or oligospermia NOS (N46.0-N46.1)”

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