ICD-10: L03.90

Cellulitis is a common and potentially serious bacterial skin infection characterized by inflammation of the skin and underlying tissues. The ICD-10-CM code L03.90 specifically refers to cellulitis, unspecified, indicating that the exact site of the infection is not specified in the diagnosis.

Clinical Description of Cellulitis

Definition

Cellulitis is an acute infection that typically affects the dermis and subcutaneous fat. It is most often caused by bacteria, primarily Staphylococcus aureus and Streptococcus pyogenes. The infection can occur anywhere on the body but is most frequently seen on the legs and face.

Symptoms

Patients with cellulitis may present with a variety of symptoms, including:
- Redness and swelling: The affected area appears red and swollen, often with a well-defined border.
- Pain and tenderness: The area may be painful to touch and can feel warm.
- Fever: Systemic symptoms such as fever and chills may accompany the localized infection.
- Blisters or pustules: In some cases, blisters may form on the skin surface.

Risk Factors

Several factors can increase the risk of developing cellulitis, including:
- Skin injuries: Cuts, insect bites, or surgical wounds can provide an entry point for bacteria.
- Chronic skin conditions: Conditions like eczema or athlete's foot can compromise the skin barrier.
- Immunocompromised states: Individuals with weakened immune systems, such as those with diabetes or HIV, are at higher risk.
- Obesity: Excess body weight can contribute to skin fold infections.

Diagnosis

The diagnosis of cellulitis is primarily clinical, based on the appearance of the skin and the patient's symptoms. In some cases, laboratory tests may be performed to identify the causative organism or to rule out other conditions. Imaging studies are generally not required unless there is suspicion of an abscess or deeper tissue involvement.

Treatment

Treatment for cellulitis typically involves:
- Antibiotics: Oral or intravenous antibiotics are prescribed based on the severity of the infection and the patient's overall health. Common choices include cephalexin, dicloxacillin, or clindamycin.
- Supportive care: Elevating the affected limb and applying cool compresses can help reduce swelling and discomfort.
- Monitoring: Patients are monitored for signs of systemic infection or complications, such as abscess formation.

Coding and Billing

The ICD-10-CM code L03.90 is used when the specific site of cellulitis is not documented. It is essential for healthcare providers to accurately document the condition to ensure appropriate coding and billing practices. If the site becomes specified later, a more specific code from the L03 category may be used.
