Breast engorgement in newborn

This code describes the physiological swelling and tenderness of a newborn's breasts due to the transfer of maternal hormones across the placenta. It is a benign, self-limiting condition typically observed in the first few days or weeks of life.

Use this code when documentation explicitly states breast engorgement in a newborn. This condition is often noted during a routine newborn examination or when a parent expresses concern about the infant's swollen breasts.

• Do not confuse with mastitis (672) or other infectious breast conditions, which are rare in newborns.
• This is a diagnosis code for the newborn, not the mother.
• Typically a secondary diagnosis when the primary reason for encounter is a well-baby check or other newborn care.
