O91.12 Abscess of breast associated with the puerperium

Name of the Condition

• Abscess of Breast Associated with the Puerperium (O91.12)

Summary

This condition involves a localized collection of pus within the breast tissue during the puerperium (postpartum period). It typically results from a bacterial infection and may present as a painful, swollen mass. Prompt medical evaluation is necessary to manage symptoms and prevent complications.

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 the puerperium 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, either through needle aspiration or surgical incision, combined with antibiotic therapy. Pain management and continued breastfeeding (if appropriate) may be recommended to maintain milk flow and prevent further complications.

Prognosis and Follow-Up

With prompt treatment, most abscesses resolve without long-term issues. Follow-up care ensures complete healing and monitors for recurrence. Patients should be advised to continue monitoring for symptoms and attend scheduled appointments.

Complications

• Spread of infection to surrounding tissue or bloodstream.
• Recurrent abscesses.
• Mastitis or other breast infections.
• Delayed wound healing.

Lifestyle & Prevention

• Maintain good breast hygiene, especially if breastfeeding.
• Ensure proper milk drainage to prevent engorgement.
• Treat cracked nipples promptly to avoid bacterial entry.
• Wear loose-fitting, breathable clothing to reduce irritation.

When to Seek Professional Help

Seek immediate medical attention if symptoms worsen, such as increasing pain, fever, or signs of spreading infection. Persistent or recurrent symptoms also warrant evaluation.

Tips for Medical Coders

Document the presence of an abscess during the puerperium, including clinical findings (e.g., fluctuance, drainage) and any associated treatments. Ensure the code O91.12 is used when the abscess is specifically linked to the postpartum period, distinguishing it from other breast abscess scenarios.
