Fissure of nipple

This code represents a linear ulcer or crack in the skin of the nipple. It is often associated with breastfeeding, trauma, or dermatological conditions affecting the breast. The fissure can cause pain, tenderness, and sometimes bleeding.

Use this code when documentation specifically identifies a fissure of the nipple. This diagnosis is commonly seen in postpartum patients experiencing breastfeeding difficulties or individuals with skin conditions affecting the areola. Documentation should clearly state "nipple fissure" or describe a crack/split in the nipple.

• Differentiate from other nipple conditions like mastitis or dermatitis, which have distinct codes.
• Consider an external cause code if the fissure is due to trauma (e.g., improper latch during breastfeeding).
• Review documentation for laterality if specified, though this code does not allow for laterality.
