Hypertrophy of breast

This code represents an abnormal enlargement or overgrowth of breast tissue in an adult, which can affect one or both breasts. It is a benign condition characterized by an increase in the size and volume of the mammary glands.

Use this code when documentation clearly indicates a diagnosis of breast hypertrophy, often presenting with symptoms such as breast pain, back pain, or aesthetic concerns due to excessive breast size. Supporting documentation should specify the diagnosis from a physician.

• Differentiate from breast engorgement in newborns (P83.4) and disproportion of reconstructed breast (N65.1), as these are "Excludes1" conditions.
• Ensure the documentation specifies "hypertrophy" and not simply "large breasts" unless further clinical context supports the pathological enlargement.
• Consider laterality if specified in the clinical notes (e.g., unilateral vs. bilateral).
