Cutaneous abscess of left upper limb

This code signifies a localized collection of pus within the skin and subcutaneous tissue of the patient's left upper extremity. It indicates an infection that has led to tissue breakdown and abscess formation, specifically affecting the arm, forearm, or hand.

Apply this code when documentation clearly states a diagnosis of a cutaneous or skin abscess located on the left upper limb. Supporting documentation should include physical exam findings describing a fluctuant, tender, erythematous mass, and often a history of infection or trauma to the area.

• Ensure the documentation specifies "cutaneous" or "skin" abscess to differentiate from deeper tissue infections.
• Verify the laterality is explicitly stated as "left upper limb"; avoid assumptions.
• Do not use this code for cellulitis without abscess formation, or for abscesses of deeper structures like muscle or bone.
