    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group N62 includes diagnoses of benign enlargement of breast tissue such as hypertrophy and macromastia that affect breast size and function. These ICD-10-CM diagnosis codes are used to document clinical scenarios involving breast overgrowth, associated symptoms like pain or functional impairment, and preoperative evaluation for reduction procedures. Accurate coding within the ICD-10-CM N62 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    Typical Clinical Scenarios

    • A 16-year-old adolescent female presents to primary care with progressive, bilateral enlargement of the breasts over the past year causing back pain and difficulty with physical activity; exam confirms symmetric excessive breast tissue without signs of infection or malignancy. She seeks evaluation for symptomatic breast hypertrophy and possible referral for conservative management or surgical consultation, so a hypertrophy diagnosis is assigned. Typical codes: N62
    • A 35-year-old pregnant woman in the second trimester reports marked breast enlargement beyond expected gestational changes, causing skin irritation and discomfort that interfere with daily activities; obstetric evaluation rules out mastitis or neoplasm. Because the presentation represents noninflammatory overgrowth of breast tissue during pregnancy as the primary issue, a hypertrophy diagnosis is used. Typical codes: N62
    • A 55-year-old woman with long-standing macromastia presents to a surgical clinic for preoperative assessment of chronic shoulder and neck pain attributed to excessive breast size; prior conservative measures have failed and she is being evaluated as a comorbidity impacting functional status and surgical risk assessment. The chronic nature of excessive breast tissue leading to functional impairment warrants coding for hypertrophy of the breast. Typical codes: N62
