N62 vs O92

N62 (Hypertrophy of breast) compared with O92 (Other disorders of breast and disorders of lactation associated with pregnancy and the puerperium), 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. N62 carries an Excludes1 note covering O92: “disorders of breast associated with childbirth (O91-O92)”

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