About the N62 Code Range
ICD-10 code N62 is used to identify various forms of hypertrophy of the breast, which refers to the abnormal enlargement or overdevelopment of breast tissue. This code helps healthcare professionals classify non-cancerous breast conditions where breast size or glandular tissue is increased.
This code covers a wide range of conditions including gynecomastia in males—whether caused by drugs or hormones like human chorionic gonadotrophin—and female breast conditions such as pubertal breast hypertrophy, gigantomastia, and overdeveloped breasts. It also applies to less common diagnoses like infantile breast hypertrophy and atypical hyperplasias of breast ducts or lobules. By using the ICD-10 code for hypertrophy of breast, medical coders can accurately capture diagnostic details related to breast size abnormalities and developmental breast findings, aiding in precise treatment planning and insurance documentation.
