Corrosion of second degree of left axilla, initial encounter

This code signifies a second-degree chemical burn affecting the left armpit area. It indicates damage to both the epidermis and dermis, characterized by blistering, pain, and redness, resulting from contact with a corrosive substance.

Apply this code when documenting the initial treatment for a patient presenting with a second-degree chemical burn to their left axilla. This includes situations like chemical spills, industrial accidents, or exposure to strong household cleaning agents that cause this specific type and location of injury.

• Ensure the documentation clearly specifies "corrosion" or "chemical burn" and the second-degree depth.
• Verify the laterality is explicitly "left" and the body site is "axilla."
• The "A" suffix indicates an initial encounter for active treatment of the injury.
