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.
