Corrosion of first degree of right ankle, initial encounter

This code signifies a superficial burn injury to the right ankle, characterized by redness and pain without blistering or skin breakage. It indicates damage limited to the outermost layer of the skin (epidermis) due to corrosive chemical exposure.

Use this code for initial encounters involving a chemical burn to the right ankle that presents as a first-degree injury. This applies when the patient is actively receiving treatment for the acute phase of the corrosion.

• Confirm the burn is explicitly stated as "corrosion" and not a thermal burn.
• Verify the anatomical site is the "right ankle" and the degree is "first degree."
• Ensure this is the initial encounter for this specific injury; subsequent care would use a different seventh character.
