This code signifies a second-degree chemical burn affecting the right ankle. This type of injury involves damage to the epidermis and dermis, characterized by blistering, significant pain, and often a red or mottled appearance.

Apply this code when documenting an initial visit for a patient presenting with a chemical burn to the right ankle that has resulted in partial-thickness tissue damage. This includes scenarios where the patient is first evaluated and treated for this specific injury.

• Ensure documentation clearly specifies the right ankle as the affected site.
• Verify the burn is explicitly described as a "corrosion" or "chemical burn" and of "second degree."
• Confirm this is the patient's first encounter for this specific injury, as indicated by the "A" seventh character.
