E35 vs N62
E35 (Disorders of endocrine glands in diseases classified elsewhere) compared with N62 (Hypertrophy of breast), 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 N62: “gynecomastia (N62)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
