Infection of nipple associated w pregnancy, first trimester

This code signifies an inflammatory or infectious process affecting the nipple area that arises during the first trimester of a pregnancy. It typically involves bacterial or fungal infections causing symptoms such as redness, swelling, pain, or discharge from the nipple. This condition is distinct from mastitis, which involves the breast tissue itself.

Apply this code when documentation clearly indicates an infection of the nipple occurring in a pregnant patient during her first trimester (up to the end of the 13th week). Supporting documentation should specify the anatomical site (nipple), the presence of infection, and the gestational period.

• Ensure the documentation explicitly states "nipple" infection, not general breast infection.
• Verify the trimester of pregnancy; this code is specific to the first trimester.
• Do not confuse with codes for non-puerperal mastitis or other breast infections not localized to the nipple.
