What Gynecomastia ICD-10 codes can I use?

If you’re looking for Gynecomastia ICD codes, please note there are no ICD-10 codes that mention Gynecomastia in their names. That doesn’t mean there aren’t any, though! They just go by different terms.

The two ICD-10 codes that you can use are the following:

  • N62 - Hypertrophy of breast

This ICD-10 code is meant to be used on a patient confirmed to have hypertrophy of the breast. Hypertrophy is the term used for enlarged organs or tissues. Gynecomastia is the enlargement or overdevelopment of breast tissue in men, so this ICD-10 code applies.

  • P83.4 - Breast engorgement of newborn

This ICD-10 code is meant to be used on a newborn patient confirmed to have breast engorgement. Breast engorgement is the swelling, tightening, and size increase of the breasts. Gynecomastia counts.

Are both these Gynecomastia ICD-10 codes billable?

Yes. Both these ICD-10 codes for Gynecomastia are valid and billable.

Clinical Information About Gynecomastia:

Gynecomastia is the term that medical professionals use to refer to the enlargement or overdevelopment of breast tissue in males. When breast tissue becomes larger or overdevelops, the breast increases in size. An imbalance of testosterone and estrogen hormones usually causes this.

Sometimes, Gynecomastia is a side effect of taking certain medications that treat anxiety, depression, male infertility, high blood pressure, and more. It can also be caused by taking anabolic steroids, opioids, amphetamines, skin care products, and even herbal supplements.

Certain conditions can also cause it, such as kidney disease, thyroid disease, liver disease, and alcoholism.
