Inclusion terms
Alternative wording in documentation that is classified to N62.
- Gynecomastia
- Hypertrophy of breast NOS
- Massive pubertal hypertrophy of breast
Excludes1 — never code together — inherited from N60-N65
The conditions below can never be reported together with N62 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- disorders of breast associated with childbirth (O91-O92)
Excludes2 — not included here — inherited from Chapter 14
The conditions below are not part of N62, but a patient may have both at the same time. When documentation supports it, N62 and the excluded code may both be reported.

- certain infectious and parasitic diseases (A00-B99)
- complications of pregnancy, childbirth and the puerperium (O00-O9A)

How long has N62 existed?
N62 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
Which codes are confused with N62?
ICD-10-CM declares these codes mutually exclusive with N62 — exactly one of each pair can be correct for a given encounter.
