ICD Code L03.90

ICD code L03.90 is used to identify a diagnosis of cellulitis that is unspecified. This means that the medical documentation indicates the presence of cellulitis, which is a bacterial skin infection characterized by redness, swelling, and pain, but does not specify the exact location or type of cellulitis. This code is often used when the healthcare provider has not detailed the specific area affected or when the documentation lacks sufficient detail to assign a more specific code.

1. Redness and Swelling: The affected area of the skin exhibits noticeable redness and swelling, often accompanied by warmth.

2. Pain and Tenderness: The patient experiences pain and tenderness in the affected area, which may worsen with touch or movement.

3. Fever: The patient may present with an elevated body temperature, indicating a systemic response to the infection.

4. Skin Lesions: The presence of skin lesions, such as blisters or pustules, may be observed in the affected area.

5. Rapid Onset: Symptoms typically develop quickly, often within a few hours to a couple of days.

6. Lymph Node Enlargement: Swelling of nearby lymph nodes may occur as the body responds to the infection.

7. General Malaise: The patient may report feeling generally unwell, fatigued, or experiencing chills.

8. History of Skin Injury: There may be a recent history of skin injury, such as a cut, abrasion, or insect bite, which could have served as an entry point for bacteria.

9. Underlying Conditions: Consideration of underlying conditions that may predispose the patient to skin infections, such as diabetes or compromised immune function.

10. Exclusion of Other Conditions: Rule out other potential causes of similar symptoms, such as deep vein thrombosis or dermatitis, to confirm the diagnosis.
