Infection of nipple associated with lactation

This code signifies an inflammatory process or infection affecting the nipple specifically during the period of breastfeeding or milk production. It typically presents with localized pain, redness, swelling, and sometimes purulent discharge from the nipple area. This condition is distinct from mastitis, which involves the breast tissue itself.

Assign this code when documentation clearly indicates an infection localized to the nipple in a lactating individual. This includes conditions like nipple candidiasis or bacterial infection of the nipple, directly attributable to the physiological state of lactation. Supporting documentation should specify the nipple as the site of infection and confirm current or recent lactation.

• Do not use for infections of the breast tissue (mastitis); refer to codes in category O91.1- for those conditions.
• Consider an additional code for the specific infectious agent (e.g., B37.0 for candidiasis) if identified.
• Ensure documentation specifies "nipple" and "lactation" to differentiate from non-puerperal nipple infections.
