About N60.0
N60.0 is the ICD-10-CM diagnosis code for Solitary cyst of breast. 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.

Related codes cover diffuse cystic mastopathy (N60.1), Fibroadenosis of breast (N60.2), fibrosclerosis of breast (N60.3), mammary duct ectasia (N60.4), other benign mammary dysplasias (N60.8) and unspecified benign mammary dysplasia (N60.9).
