Corrosion of second degree of left forearm, init encntr

This diagnosis code signifies a second-degree chemical burn affecting the left forearm. It indicates damage to the epidermis and dermis, characterized by blistering, pain, and redness, resulting from exposure to a corrosive substance. This specific code is used for the initial treatment of such an injury.

Apply this code when documenting the first encounter for a patient presenting with a second-degree chemical burn on their left forearm. This includes initial assessment, treatment, and management of the acute injury. It is appropriate for cases where the corrosive agent has caused significant skin damage beyond superficial irritation.

• Ensure the documentation clearly specifies "corrosion" or "chemical burn" and the degree as "second."
• Verify the laterality is explicitly stated as "left forearm" in the medical record.
• The "A" seventh character indicates an initial encounter for active treatment of the injury.
