ICD-10: L02.622

Furuncle, commonly known as a boil, is a painful infection that forms around a hair follicle or oil gland. The ICD-10-CM code L02.622 specifically refers to a furuncle located on the left foot. Below is a detailed clinical description and relevant information regarding this condition.

Clinical Description of Furuncle (L02.622)

Definition

A furuncle is a deep follicular infection that typically results from the bacteria Staphylococcus aureus. It manifests as a red, swollen, and painful lump filled with pus. The infection can occur anywhere on the body but is particularly common in areas where friction or sweating occurs, such as the feet.

Symptoms

• Localized Pain: The area around the furuncle is often tender and painful.
• Swelling and Redness: The skin surrounding the boil becomes inflamed and red.
• Pus Formation: A central core of pus may develop, leading to the formation of a head on the boil.
• Fever: In some cases, systemic symptoms like fever may occur, especially if the infection spreads.

Causes

Furuncles are primarily caused by bacterial infections, with Staphylococcus aureus being the most common pathogen. Factors that may contribute to the development of a furuncle include:
- Poor Hygiene: Inadequate cleaning of the skin can lead to bacterial overgrowth.
- Skin Irritation: Friction from clothing or footwear can irritate hair follicles.
- Underlying Conditions: Conditions such as diabetes or immunosuppression can increase susceptibility to skin infections.

Diagnosis

Diagnosis of a furuncle is typically clinical, based on the appearance of the lesion and associated symptoms. In some cases, a culture of the pus may be taken to identify the causative organism, especially if the infection is recurrent or severe.

Treatment

Treatment options for a furuncle include:
- Incision and Drainage (I&D): This is often the first-line treatment for larger or more painful boils. The procedure involves making a small incision to allow the pus to drain, which can relieve pain and promote healing[2][5].
- Antibiotics: If the infection is severe or if there are signs of systemic involvement, antibiotics may be prescribed. The choice of antibiotic may depend on the culture results[2][5].
- Warm Compresses: Applying warm compresses can help promote drainage and alleviate discomfort.

Coding and Billing

The ICD-10-CM code L02.622 is used for billing and coding purposes to specify a furuncle located on the left foot. Accurate coding is essential for proper documentation and reimbursement in healthcare settings. This code falls under the broader category of skin and subcutaneous tissue infections, specifically those classified as furuncles[1][10].

Conclusion

Furuncle of the left foot, designated by ICD-10 code L02.622, is a localized skin infection that can cause significant discomfort. Understanding its clinical presentation, causes, and treatment options is crucial for effective management. If you suspect a furuncle, especially if it is recurrent or accompanied by systemic symptoms, it is advisable to seek medical attention for appropriate care and intervention.

Understanding the clinical presentation, signs, symptoms, and patient characteristics associated with this condition is essential for accurate diagnosis and treatment.

Clinical Presentation

Definition and Pathophysiology

A furuncle is an infection of a hair follicle that leads to the formation of a painful, swollen lump filled with pus. It can occur anywhere on the body but is particularly common in areas where friction or sweating occurs. The infection can arise from a variety of factors, including skin trauma, poor hygiene, or underlying health conditions that compromise the immune system.

Signs and Symptoms

Patients with a furuncle of the left foot may exhibit the following signs and symptoms:

• Localized Pain and Tenderness: The area around the furuncle is often painful to touch, and the pain may increase as the infection progresses.
• Swelling and Redness: The skin surrounding the furuncle typically appears red and swollen, indicating inflammation.
• Pus Formation: As the furuncle matures, it fills with pus, which may eventually drain if the boil ruptures.
• Warmth: The affected area may feel warm to the touch due to increased blood flow and inflammation.
• Fever: In some cases, patients may develop a low-grade fever as the body responds to the infection.
• Systemic Symptoms: If the infection spreads, patients may experience fatigue, malaise, or other systemic symptoms.

Patient Characteristics

Certain patient characteristics may predispose individuals to develop furuncles, including:

• Age: While furuncles can occur at any age, they are more common in adolescents and young adults.
• Skin Type: Individuals with oily skin or those who sweat excessively may be more prone to developing furuncles.
• Underlying Health Conditions: Conditions such as diabetes, obesity, or immunosuppression (e.g., due to HIV/AIDS or chemotherapy) can increase the risk of skin infections.
• Hygiene Practices: Poor hygiene or skin care practices can contribute to the development of furuncles.
• Recent Skin Trauma: Any recent cuts, abrasions, or insect bites on the foot can serve as entry points for bacteria.

Diagnosis and Management

Diagnosis of a furuncle typically involves a physical examination and a review of the patient's medical history. In some cases, a culture of the pus may be taken to identify the causative organism and determine appropriate antibiotic treatment.

Treatment Options

• Incision and Drainage: If the furuncle is large or painful, a healthcare provider may perform an incision and drainage procedure to relieve pressure and promote healing.
• Antibiotics: Depending on the severity of the infection and the patient's overall health, antibiotics may be prescribed to combat the bacterial infection.
• Pain Management: Over-the-counter pain relievers, such as ibuprofen or acetaminophen, can help alleviate discomfort.
