Corrosion of second degree of unspecified ankle, init encntr

This code signifies a second-degree burn, specifically a corrosion injury, affecting an unspecified ankle. A second-degree burn involves damage to the epidermis and dermis, characterized by blistering, pain, and redness. Corrosion injuries are caused by contact with corrosive substances like strong acids or alkalis.

Use this code for a patient presenting with a second-degree chemical burn to the ankle, where the specific ankle (left or right) is not documented. This code is appropriate for the initial treatment of such an injury.

• Ensure documentation clearly states "corrosion" or "chemical burn" and specifies the ankle as the affected site.
• Verify the burn depth is explicitly noted as "second degree."
• Confirm this is the first time the patient is being treated for this specific injury to use the "A" (initial encounter) seventh character.
