About N60

N60 is the ICD-10-CM diagnosis code for benign mammary dysplasia. It belongs to block N60-N65 (disorders of breast) and chapter 14 (diseases of the genitourinary system). It is a header code, so it can't be reported by itself; one of its 7 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: N60.0 (breast), N60.1 (mastopathy), N60.2 (breast), N60.3 (breast), N60.4 (ectasia), N60.8 (dysplasias) and N60.9 (dysplasia).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
