Cellulitis of unspecified finger

This code signifies a bacterial skin infection characterized by inflammation, redness, warmth, and swelling affecting the subcutaneous tissue of an unspecified finger. It indicates a non-necrotizing infection that has not progressed to abscess formation or gangrene.

Apply this code when documentation clearly states "cellulitis of finger" without specifying which digit is affected. It is appropriate for cases where the physician's assessment identifies cellulitis but the exact finger (e.g., thumb, index finger) is not documented.

• Avoid using this code if the specific finger is identified; instead, use a more precise code from the L03.01- series (e.g., L03.011 for right thumb).
• Do not use this code for abscesses, which are coded separately (e.g., L02.41- series).
• Sequence this code as a primary diagnosis when cellulitis is the reason for the encounter.
