ICD-10: L02.62

Furuncle, commonly known as a boil, is a painful, pus-filled bump that forms under the skin due to a bacterial infection, typically caused by Staphylococcus aureus. The ICD-10 code L02.62 specifically refers to a furuncle located on the foot, which is classified under the broader category of cutaneous abscesses, furuncles, and carbuncles.

Clinical Description

Definition

A furuncle is an acute, localized infection of the hair follicle that leads to the formation of a painful, swollen area filled with pus. When multiple hair follicles are involved, the condition may escalate to a carbuncle, which is a cluster of interconnected furuncles.

Symptoms

The symptoms associated with a furuncle of the foot include:
- Pain and Tenderness: The affected area is often painful to touch and may be tender.
- Swelling and Redness: There is typically noticeable swelling and redness surrounding the infected hair follicle.
- Pus Formation: A central point of pus may develop, which can eventually rupture and drain.
- Fever: In some cases, systemic symptoms such as fever may occur, indicating a more severe infection.

Risk Factors

Several factors can increase the likelihood of developing a furuncle, including:
- Poor Hygiene: Inadequate cleaning of the skin can lead to bacterial growth.
- Diabetes: Individuals with diabetes are at a higher risk due to compromised immune function.
- Skin Conditions: Conditions like eczema or acne can predispose individuals to furuncles.
- Close Contact: Sharing personal items or close skin-to-skin contact with an infected person can facilitate the spread of bacteria.

Diagnosis

Diagnosis of a furuncle is primarily clinical, based on the appearance of the lesion and associated symptoms. In some cases, a healthcare provider may perform a culture of the pus to identify the causative bacteria, especially if the infection is recurrent or severe.

Treatment

Treatment options for a furuncle of the foot may include:
- Incision and Drainage (I&D): This is often the first-line treatment for larger or more painful furuncles, allowing for the release of pus and pressure relief.
- Antibiotics: If the infection is severe or if there are signs of systemic involvement, antibiotics may be prescribed to combat the bacterial infection.
- Warm Compresses: Applying warm compresses can help promote drainage and alleviate pain.

Coding Information

The ICD-10-CM code for a furuncle of the foot is L02.62, which falls under the category of cutaneous abscesses, furuncles, and carbuncles (L02.6). This code is essential for accurate medical billing and documentation, ensuring that healthcare providers can effectively communicate the diagnosis for treatment and insurance purposes[1][2][3].

In summary, a furuncle of the foot is a localized skin infection that requires prompt attention to prevent complications. Proper diagnosis and treatment are crucial for effective management and recovery.

Furuncle of the foot, classified under ICD-10 code L02.62, is a type of skin infection that presents with specific clinical features and patient characteristics. Understanding these aspects is crucial for accurate diagnosis and effective treatment.

Clinical Presentation

Furuncles, commonly known as boils, are painful, pus-filled bumps that form under the skin due to bacterial infection, typically caused by Staphylococcus aureus. When located on the foot, they can significantly impact mobility and quality of life.

Signs and Symptoms

1. Localized Swelling: The affected area on the foot will exhibit noticeable swelling, which may be tender to the touch.

The diagnosis of a furuncle, specifically coded as ICD-10 code L02.62, which refers to a furuncle of the foot, involves several clinical criteria and considerations. Here’s a detailed overview of the diagnostic criteria and relevant information regarding this condition.

Understanding Furuncles

A furuncle, commonly known as a boil, is a painful, pus-filled bump that forms under the skin due to an infection of a hair follicle. The infection is typically caused by Staphylococcus aureus, a type of bacteria that can enter the body through small cuts or abrasions.

Diagnostic Criteria for Furuncle of the Foot (ICD-10 L02.62)

1. Clinical Presentation

• Localized Swelling: The presence of a painful, swollen area on the foot, often red and warm to the touch.
• Pus Formation: The formation of a central pustule or abscess that may eventually drain.
• Pain and Tenderness: Increased sensitivity in the affected area, which may worsen with pressure.

2. History Taking

• Recent Trauma: Inquiry about any recent injuries or skin breaks on the foot that could have allowed bacteria to enter.
• Previous Episodes: A history of recurrent furuncles or skin infections may be relevant.
• Underlying Conditions: Assessment for conditions such as diabetes or immunosuppression that could predispose the patient to infections.

3. Physical Examination

• Inspection: A thorough examination of the foot to identify the location and extent of the furuncle.
• Palpation: Checking for tenderness, fluctuation (indicating pus), and surrounding cellulitis (inflammation of the skin).

4. Laboratory Tests (if necessary)

• Culture and Sensitivity: In cases of severe infection or recurrent furuncles, a culture of the pus may be taken to identify the causative organism and determine antibiotic sensitivity.
• Blood Tests: Complete blood count (CBC) may be performed to check for signs of systemic infection, such as elevated white blood cell count.

5. Differential Diagnosis

• Abscess: Distinguishing between a furuncle and other types of skin abscesses.
• Other Skin Conditions: Considering other dermatological conditions that may mimic a furuncle, such as hidradenitis suppurativa or folliculitis.
