L02.32 Furuncle of buttock

Name of the Condition

• Furuncle of Buttock

Summary

A furuncle of the buttock is a localized, painful infection of a hair follicle and surrounding skin tissue, resulting in a pus-filled lesion. It typically presents as a tender, red, and swollen nodule that may develop a central core of pus. This condition arises from bacterial invasion, most commonly Staphylococcus aureus, and can cause discomfort or complications if left untreated.

Causes

The primary cause is a bacterial infection, typically Staphylococcus aureus. Infections occur when bacteria enter the skin through breaks, such as minor cuts, blocked hair follicles, or friction. The buttock area, due to its skin folds and potential for moisture, may be more susceptible to such entry points.

Risk Factors

• Poor personal hygiene
• Compromised immune system (e.g., diabetes, HIV)
• Skin conditions (e.g., acne, eczema)
• Friction or irritation from tight clothing
• Recent skin trauma or surgery in the buttock area

Symptoms

• Red, swollen, and painful lump on the buttock
• Warmth around the affected area
• Pus-filled center (may drain spontaneously)
• Fever or chills (in severe cases)
• Swollen nearby lymph nodes

Diagnosis

Diagnosis is typically made through a physical examination by a healthcare provider, who assesses the lesion’s appearance, location, and associated symptoms. In some cases, a sample of pus may be collected for culture to identify the causative bacteria and guide treatment.

Treatment Options

Treatment may include warm compresses to promote drainage, topical or oral antibiotics to address infection, and pain management. For larger or persistent furuncles, incision and drainage by a healthcare provider may be necessary. Proper hygiene and wound care are also recommended.

Prognosis and Follow-Up

With appropriate treatment, most furuncles resolve within 1–2 weeks. Follow-up may be advised to ensure healing and monitor for recurrence. If symptoms worsen or persist, further evaluation may be needed to rule out complications.

Complications

Potential complications include the spread of infection to deeper tissues (cellulitis), formation of a larger abscess, or systemic infection (sepsis) in severe cases. Scarring may occur after drainage or healing.

Lifestyle & Prevention

• Maintain good personal hygiene, especially in the buttock area.
• Wear loose-fitting clothing to reduce friction and moisture.
• Avoid sharing personal items (e.g., towels) to prevent bacterial spread.
• Keep the skin clean and dry, particularly after exercise or sweating.

When to Seek Professional Help

Seek medical attention if the furuncle is large, worsening, or accompanied by fever, chills, or increasing pain. Prompt care is recommended if the lesion does not improve with home care or shows signs of spreading.

Tips for Medical Coders

Document the location (buttock) and clinical findings (e.g., presence of pus, tenderness) to support coding. Ensure the diagnosis aligns with the specific characteristics of a furuncle, as opposed to other skin infections. Verify that the code L02.32 is used for isolated buttock involvement, with no additional codes for complications unless present.
