O91.019 Infection of nipple associated with pregnancy, unspecified trimester

Name of the Condition

• Infection of Nipple Associated with Pregnancy, Unspecified Trimester (O91.019)

Summary

Infection of the nipple associated with pregnancy, unspecified trimester, is a localized infection occurring during pregnancy when the specific trimester is not documented. It may involve bacterial or fungal pathogens and can present with symptoms like pain, redness, or discharge. Prompt evaluation and treatment are important to manage symptoms and prevent progression.

Causes

The condition is typically caused by bacterial organisms, such as Staphylococcus aureus or Streptococcus species, which enter through damaged nipple skin. Fungal infections, like Candida, may also occur. Contributing factors include cracked nipples, poor hygiene, or trauma to the nipple area.

Risk Factors

• Cracked or damaged nipples from hormonal changes or breastfeeding.
• Poor hygiene practices.
• History of previous breast or nipple infections.
• Use of tight or non-breathable clothing.
• Weakened immune system during pregnancy.

Symptoms

• Pain, tenderness, or swelling of the nipple.
• Redness or warmth in the affected area.
• Discharge (pus or fluid) from the nipple.
• Itching or burning sensation, especially with fungal infections.
• Fever or systemic symptoms in severe cases.

Diagnosis

Diagnosis is based on clinical evaluation, including physical examination of the nipple for signs of infection. Cultures of nipple discharge may be taken to identify the causative organism. Further testing is rarely needed unless deeper tissue involvement is suspected.

Treatment Options

Treatment typically involves topical or oral antibiotics for bacterial infections, antifungal medications for fungal cases, and pain management. Proper hygiene and nipple care are also recommended to support healing.

Prognosis and Follow-Up

With appropriate treatment, most infections resolve without complications. Follow-up may be needed to ensure symptoms improve and to address any underlying issues, such as persistent nipple damage.

Complications

Untreated infections may progress to mastitis, abscess formation, or systemic infection. Severe cases can disrupt breastfeeding or require additional interventions.

Lifestyle & Prevention

• Maintain good nipple hygiene during pregnancy.
• Use lanolin or moisturizers to prevent cracking.
• Wear loose, breathable clothing.
• Avoid harsh soaps or lotions on the nipple area.
• Seek prompt care for any signs of infection.

When to Seek Professional Help

Consult a healthcare provider if symptoms worsen, persist, or include fever, severe pain, or discharge that does not improve with home care.

Tips for Medical Coders

Document the trimester when known, as this affects code specificity. For unspecified trimester, use O91.019. Ensure clinical documentation supports the diagnosis, including symptoms and any cultures or treatments provided.
