2025 ICD-10-CM code P39.0
Neonatal infective mastitis. This is an infection of the breast tissue in newborns.
Medical necessity for treating neonatal infective mastitis stems from the potential for the infection to spread and cause more serious complications, such as sepsis. Prompt diagnosis and treatment are essential to prevent these adverse outcomes and ensure the infant's well-being.
Diagnosis and treatment of neonatal infective mastitis typically fall under the purview of pediatricians or neonatologists. They are responsible for assessing the infant, determining the cause of the infection, and prescribing appropriate treatment, which may include antibiotics.They also provide guidance on supportive care, such as pain management and ensuring adequate feeding.

In simple words: A newborn baby's breast tissue has become infected and inflamed. This can cause redness, swelling, pain, and sometimes fever.
Neonatal infective mastitis is an infection of the breast tissue that occurs in newborns, typically within the first 28 days of life. It's characterized by inflammation of the mammary gland due to bacterial penetration.Symptoms can include redness, swelling, warmth in the affected area, pain, and possibly fever.
Example 1: A 5-day-old female newborn presents with redness, swelling, and tenderness in her right breast. The area is warm to the touch, and she has a low-grade fever. After examination and possibly lab tests, she is diagnosed with neonatal infective mastitis., A 10-day-old male newborn exhibits signs of breast infection, including redness and swelling. The pediatrician diagnoses neonatal infective mastitis and prescribes antibiotics to address the infection., A 2-week-old newborn develops a localized breast abscess.This is a more severe form of neonatal infective mastitis that may require additional interventions, such as drainage of the abscess.
Documentation should include a detailed description of the physical findings, including the location and extent of the inflammation, presence of any discharge, and associated symptoms like fever. Any laboratory tests performed (e.g., cultures) and their results should also be documented.The infant's response to treatment should be noted as well.
** Excludes1: breast engorgement of newborn (P83.4) and noninfective mastitis of newborn (P83.4). Parent Code Notes: P39 – Use additional code to identify organism or specific infection.
