About coding Fibroadenosis
The ICD-10-CM code for Fibroadenosis is N60.2 (Fibroadenosis of breast).

Related codes cover Solitary cyst of breast (N60.0), diffuse cystic mastopathy (N60.1), fibrosclerosis of breast (N60.3), mammary duct ectasia (N60.4), other benign mammary dysplasias (N60.8) and unspecified benign mammary dysplasia (N60.9).
