ICD-10: B35.4

Tinea corporis, commonly known as ringworm of the body, is a fungal infection characterized by circular, red, itchy patches on the skin. It is classified under the ICD-10 code B35.4. The management of tinea corporis typically involves antifungal treatments, which can be administered topically or systemically, depending on the severity and extent of the infection.

Standard Treatment Approaches

1. Topical Antifungal Agents

For localized cases of tinea corporis, topical antifungal medications are the first line of treatment. These include:

• Azoles: Clotrimazole, miconazole, and ketoconazole are commonly used. They work by inhibiting the synthesis of ergosterol, a key component of fungal cell membranes.
• Allylamines: Terbinafine and naftifine are effective alternatives that disrupt fungal cell membrane integrity.
• Other Options: Tolnaftate and ciclopirox are also used, though they may be less effective than azoles and allylamines.

Topical treatments are usually applied once or twice daily for 2 to 4 weeks, depending on the product and the severity of the infection[1][5].

2. Systemic Antifungal Therapy

In cases where tinea corporis is extensive, recurrent, or does not respond to topical treatments, systemic antifungal therapy may be necessary. Commonly prescribed oral antifungals include:

• Terbinafine: Typically administered for 4 to 6 weeks, it is effective against a wide range of dermatophytes.
• Itraconazole: Another option, often used for 1 to 2 months, particularly in cases of extensive infection or when tinea corporis is associated with tinea capitis (scalp infection).
• Fluconazole: This may also be used, especially in cases where other treatments are ineffective.

Systemic treatments are particularly important for immunocompromised patients or those with extensive lesions[2][4].

3. Adjunctive Measures

In addition to antifungal medications, several adjunctive measures can help manage tinea corporis:

• Hygiene Practices: Keeping the affected area clean and dry is crucial, as fungi thrive in moist environments. Regular washing and thorough drying of the skin can help prevent the spread of the infection.
• Avoiding Irritants: Patients should avoid tight clothing and synthetic fabrics that can trap moisture and irritate the skin.
• Environmental Control: Fungal spores can survive in the environment, so cleaning and disinfecting shared spaces, such as locker rooms and showers, is important to prevent reinfection[3][6].

4. Monitoring and Follow-Up

Regular follow-up is essential to ensure the effectiveness of the treatment. If symptoms persist or worsen, further evaluation may be necessary to rule out other conditions or to consider alternative treatments. In some cases, a skin scraping or culture may be performed to confirm the diagnosis and identify the specific fungal organism involved[1][5].

Conclusion

The management of tinea corporis (ICD-10 code B35.4) primarily involves the use of topical or systemic antifungal agents, depending on the severity of the infection. Adhering to proper hygiene practices and environmental controls can significantly aid in treatment success and prevent recurrence. Regular monitoring and follow-up are crucial to ensure effective management and address any complications that may arise.

Tinea corporis, commonly known as ringworm, is a dermatological condition characterized by a fungal infection affecting the skin. The ICD-10-CM code for this condition is B35.4. Below is a detailed clinical description and relevant information regarding Tinea corporis.

Clinical Description of Tinea Corporis

Etiology

Tinea corporis is caused by dermatophytes, a group of fungi that thrive on keratin found in the skin, hair, and nails. The most common species responsible for this infection include Trichophyton rubrum, Trichophyton mentagrophytes, and Microsporum canis. These fungi can be transmitted through direct contact with infected individuals, animals, or contaminated surfaces and objects, such as clothing and towels[1][2].

Symptoms

The clinical presentation of Tinea corporis typically includes:
- Rash: The hallmark of Tinea corporis is a circular, red, scaly patch with raised edges. The center of the lesion may appear clearer, giving it a ring-like appearance, hence the name "ringworm."
- Itching: Patients often experience pruritus (itching) in the affected areas, which can lead to scratching and secondary infections.
- Scaling: The skin may exhibit scaling, which can vary in severity depending on the individual and the extent of the infection.

Diagnosis

Diagnosis of Tinea corporis is primarily clinical, based on the characteristic appearance of the rash. However, laboratory tests may be conducted to confirm the diagnosis, including:
- KOH Preparation: A skin scraping can be examined under a microscope after treatment with potassium hydroxide (KOH) to identify fungal elements.
- Fungal Culture: Culturing the skin sample can help identify the specific dermatophyte responsible for the infection.

Treatment

Treatment for Tinea corporis typically involves antifungal medications, which can be administered topically or orally, depending on the severity of the infection:
- Topical Antifungals: Over-the-counter options include clotrimazole, miconazole, and terbinafine. These are usually effective for localized infections.
- Oral Antifungals: In cases of extensive infection or when topical treatments fail, systemic antifungals such as griseofulvin or itraconazole may be prescribed.

Prognosis

With appropriate treatment, Tinea corporis generally has a good prognosis, and symptoms typically resolve within a few weeks. However, recurrence is common, especially in individuals with risk factors such as immunosuppression or those living in warm, humid environments[3][4].

ICD-10-CM Code B35.4

The ICD-10-CM code B35.4 specifically refers to Tinea corporis. This code is part of the broader category of dermatophytosis (B35), which encompasses various fungal infections of the skin. Accurate coding is essential for proper diagnosis, treatment, and billing purposes in clinical settings.
