Corrosion of first degree of left forearm, initial encounter

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

Apply this code when documenting a patient's initial presentation for a first-degree chemical burn affecting their left forearm. This includes situations where the patient is being evaluated and treated for the acute injury.

• Ensure the documentation specifies "corrosion" or "chemical burn" and not a thermal burn.
• Verify the burn degree is explicitly stated as "first degree."
• Confirm the anatomical site is the "left forearm" and this is the "initial encounter" for this specific injury.
