Corrosion of second degree of left toe(s) (nail), init

This code signifies a second-degree chemical burn affecting the toes or toenail of the left foot. This type of injury involves damage to the epidermis and dermis, typically presenting with blistering, significant pain, and redness.

Apply this code when documenting a patient's initial presentation for a second-degree corrosion injury to the left toe(s) or toenail. This includes cases where the patient is first seen for evaluation and treatment of the chemical burn.

• Ensure the documentation clearly specifies "corrosion" (chemical burn) rather than a thermal burn.
• Verify the laterality is explicitly stated as "left" and the degree of burn is "second degree."
• Confirm this is the patient's first encounter for this specific injury to use the "A" (initial encounter) seventh character.
