Breast engorgement of newborn

This code signifies the physiological swelling and tenderness of the breast tissue in a newborn, typically due to the influence of maternal hormones. It is a benign, self-limiting condition that can affect both male and female infants.

Assign this code when documentation explicitly states breast engorgement in a newborn. This condition is often observed within the first few weeks of life and is usually noted during a well-baby check or a visit for other newborn concerns.

• Ensure documentation specifies "newborn" to differentiate from maternal breast engorgement (O92.70-O92.79).
• This code is typically a secondary diagnosis, as the newborn is often seen for routine care or other primary issues.
• Do not confuse with mastitis (P39.0), which involves infection and inflammation.
