E23.0 vs E29
E23.0 (Hypopituitarism) compared with E29 (Testicular dysfunction), 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 E23.0: “isolated gonadotropin deficiency (E23.0)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
