Cellulitis and abscess of trunk

This code signifies an acute bacterial infection of the skin and subcutaneous tissue (cellulitis) or a localized collection of pus (abscess) affecting the torso, including the chest, abdomen, back, and pelvis. These conditions are characterized by inflammation, pain, redness, swelling, and sometimes fever.

Use this code when documentation clearly indicates cellulitis or an abscess located anywhere on the trunk. This includes infections of the abdominal wall, back, chest wall, or gluteal region. Supporting documentation should specify the anatomical site within the trunk.

• Differentiate from superficial skin infections like impetigo or folliculitis, which have different codes.
• Ensure the documentation specifies "trunk" or a specific anatomical site within the trunk (e.g., "abdominal cellulitis").
• If an infectious organism is identified, code it as an additional diagnosis.
