O91.13 Abscess of breast associated with lactation

Name of the Condition

• Abscess of Breast Associated with Lactation (O91.13)

Summary

This condition involves a localized collection of pus within breast tissue during lactation. It typically results from a bacterial infection and may present as a painful, swollen mass. Prompt medical evaluation is necessary to prevent complications and guide appropriate treatment.

Causes

Abscesses usually develop when bacteria, such as Staphylococcus aureus, enter the breast tissue through a break in the skin or milk ducts. This can occur due to cracked nipples, blocked milk ducts, or inadequate milk drainage. Hormonal changes during lactation may also increase susceptibility to infection.

Risk Factors

• Cracked or damaged nipples during breastfeeding.
• Inadequate milk removal or engorgement.
• Previous breast infections or abscesses.
• Poor hygiene practices.
• Weakened immune system.

Symptoms

• Localized breast pain, swelling, or redness.
• Palpable, tender lump with fluctuance.
• Fever or chills.
• Nipple discharge or pus.
• Skin warmth or discoloration over the affected area.

Diagnosis

Diagnosis is based on clinical evaluation, including physical examination for signs of abscess formation. Ultrasound may be used to confirm the presence and extent of the abscess. Cultures of discharge or aspirated fluid may identify the causative organism.

Treatment Options

Treatment typically involves drainage of the abscess, often with ultrasound guidance, and antibiotic therapy to address the underlying infection. Pain management and continued breastfeeding support may also be provided.

Prognosis and Follow-Up

With appropriate treatment, most abscesses resolve without long-term complications. Follow-up care ensures complete healing and monitors for recurrence. Breastfeeding can usually continue with proper guidance.

Complications

• Spread of infection to surrounding tissue or bloodstream.
• Recurrent abscesses.
• Scarring or tissue damage.
• Interrupted lactation.

Lifestyle & Prevention

• Maintain good nipple hygiene during breastfeeding.
• Ensure proper milk drainage to prevent engorgement.
• Address cracked nipples promptly to avoid infection entry points.
• Use proper breastfeeding techniques to reduce trauma.

When to Seek Professional Help

Seek medical attention if symptoms worsen, fever persists, or the abscess does not improve with initial care. Immediate evaluation is needed for signs of systemic infection or severe pain.

Tips for Medical Coders

Document the association with lactation clearly, as this distinguishes the condition from other breast abscess codes. Include details on clinical presentation, diagnostic methods, and treatment to support accurate coding.
