N60.8Other benign mammary dysplasias

N60.8 is the ICD-10-CM diagnosis code for other benign mammary dysplasias. It belongs to category N60 (benign mammary dysplasia), 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 3 subcodes must be used instead.

Within N60, choose N60.8 (Other benign mammary dysplasias) only when documentation doesn't support a more specific option: Solitary cyst of breast (N60.0), diffuse cystic mastopathy (N60.1), Fibroadenosis of breast (N60.2), fibrosclerosis of breast (N60.3), mammary duct ectasia (N60.4) and unspecified benign mammary dysplasia (N60.9).

To report this condition, pick the subcode that matches the documentation: N60.81 (of right breast), N60.82 (of left breast) and N60.89 (of unspecified breast).

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