Corrosion of first degree of left ankle, initial encounter

This code signifies a superficial burn injury to the left 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 substances.

Apply this code for patients presenting with a first-degree chemical burn to the left ankle, such as from contact with a mild acid or alkali. This code is appropriate for the initial treatment of the injury.

• Ensure documentation specifies "left ankle" and "first degree" for accurate coding.
• Verify the cause is a "corrosion" (chemical burn) rather than a thermal burn.
• Confirm this is the initial encounter for treatment of this specific injury.
