Hypertrophy of breast

This code describes an abnormal enlargement of one or both breasts due to an increase in breast tissue. It can manifest as macromastia or gigantomastia, causing physical discomfort, pain, and psychosocial distress.

Use this code for documented cases of breast hypertrophy, often presenting with symptoms like back pain, shoulder pain, grooving from bra straps, or difficulty with physical activity. Supporting documentation includes physician notes detailing breast size, patient complaints related to breast size, and physical examination findings.

• Differentiate from gynecomastia (enlargement of male breast tissue), which has separate codes.
• Do not use for breast enlargement due to pregnancy, lactation, or obesity without true glandular hypertrophy.
• Consider laterality if specified in the documentation (e.g., unilateral vs. bilateral).
