E35 vs N64.3
E35 (Disorders of endocrine glands in diseases classified elsewhere) compared with N64.3 (Galactorrhea not associated with childbirth), 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. E35 carries an Excludes1 note covering N64.3: “galactorrhea (N64.3)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
