Cellulitis and abscess of leg, except foot

This code signifies an acute bacterial infection of the skin and subcutaneous tissue of the lower extremity, excluding the foot. It encompasses both diffuse inflammation (cellulitis) and localized collections of pus (abscess) affecting the leg.

Apply this code when documentation clearly indicates cellulitis or an abscess located anywhere on the leg, from the knee to the ankle, but not involving the foot. Supporting documentation would include physician notes detailing erythema, warmth, swelling, tenderness, and/or purulent drainage in the specified anatomical area.

• Differentiate from infections of the foot; if the foot is involved, a more specific code should be used.
• Ensure the documentation specifies "leg" and not a broader lower extremity term if the infection crosses anatomical boundaries.
• Consider an additional code for the causative organism if identified and documented.
