Cellulitis of left finger

This code signifies an acute bacterial infection of the skin and subcutaneous tissue affecting a finger on the patient's left hand. It presents with localized redness, swelling, warmth, and tenderness, often without a clearly defined border. The infection can spread rapidly if left untreated.

Use this code when documentation explicitly states cellulitis affecting any digit of the left hand. This typically arises from a break in the skin, such as a cut, abrasion, insect bite, or fungal infection. Supporting documentation should detail the location of the infection as the left finger.

• Ensure laterality is clearly documented as "left finger" to support this specific code.
• Distinguish from abscess (L02.-) or erysipelas (A46), which have distinct clinical presentations and coding.
• If an underlying wound or injury is the source, code the wound first, followed by the cellulitis.
