Benign mammary dysplasia (N60)

ICD-10 code N60 covers benign mammary dysplasia, a group of noncancerous breast conditions. This section includes codes for various cysts, fibrocystic changes, fibroadenosis, and other benign changes in breast tissue, specified by the affected breast.

This set of codes is used to classify benign breast changes such as solitary cysts (N60.0 series), which are fluid-filled sacs in one or both breasts. Terms like cysts of the right or left breast and complex or simple cysts correspond to codes N60.01, N60.02, and N60.09 respectively. Diffuse cystic mastopathy (N60.1 series) refers to widespread cystic changes, often called "fibrocystic disease," detailed by right, left, or unspecified breast. Fibroadenosis (N60.2 series) involves fibrous and glandular tissue changes, sometimes known as "benign mammary dysplasia" or "sclerosing adenosis." Fibrosclerosis (N60.3 series) and mammary duct ectasia (N60.4 series) define fibrotic and ductal changes, with synonyms like induration or plasma cell mastitis. Codes in N60.8 and N60.9 cover other and unspecified benign dysplasias, including atypical hyperplasia and sebaceous cysts. These codes help healthcare professionals document nonmalignant breast conditions accurately and monitor their management.
