Cellulitis of right finger

This code signifies a bacterial infection of the skin and subcutaneous tissue affecting the right finger. It presents as a localized area of redness, swelling, warmth, and tenderness, often with poorly defined borders. The infection can spread rapidly if left untreated.

Apply this code when documentation clearly indicates cellulitis localized to any digit of the right hand. Supporting documentation should include physical exam findings consistent with cellulitis and specify the affected side (right) and body part (finger). This code is appropriate for both initial and subsequent encounters for this condition.

• Ensure the documentation specifies "right" finger; if left or unspecified, a different code is required.
• Distinguish from abscess (L02.-) or erysipelas (A46), which have distinct clinical presentations and coding.
• Code any associated open wound or injury separately, following sequencing guidelines for primary and secondary diagnoses.
