Corrosion of first degree of left foot, initial encounter

This code signifies a superficial chemical burn affecting the left foot, characterized by redness and mild pain without blistering or skin loss. The injury is limited to the epidermis, indicating a first-degree corrosion.

Apply this code when documenting a patient's initial presentation for a chemical burn to the left foot that presents as a first-degree injury. This is appropriate for acute exposures where the patient is seeking initial treatment.

• Ensure the documentation specifies "corrosion" (chemical burn) rather than a thermal burn.
• Verify the laterality is explicitly stated as "left foot."
• Confirm this is the initial encounter for this specific injury.
