Abscess of breast associated with pregnancy, first trimester

This code identifies a localized collection of pus within the breast tissue that develops during the first trimester of pregnancy. It signifies an infectious process requiring medical intervention, distinct from non-infectious breast conditions.

Apply this code when documentation clearly indicates a breast abscess occurring in a pregnant patient during her first trimester. Supporting documentation should include a diagnosis of breast abscess and confirmation of the gestational period.

• Ensure the documentation explicitly states "abscess" and not just mastitis, as an abscess is a more severe form of infection.
• Verify the trimester of pregnancy is clearly documented as the first trimester (weeks 1-12).
• Do not use this code for breast abscesses occurring postpartum or unrelated to pregnancy.
