Corrosion of second degree of left foot, initial encounter

This code signifies a partial-thickness skin injury to the left foot caused by a corrosive substance, such as a strong acid or alkali. The damage extends beyond the epidermis into the dermis, characterized by blistering, significant pain, and often a red or mottled appearance.

Apply this code when documenting a patient presenting with a second-degree chemical burn to their left foot. This is appropriate for the initial visit or encounter for this specific injury, indicating the active phase of treatment.

• Confirm the laterality (left foot) and the degree of corrosion (second degree) from the physician's documentation.
• Ensure the encounter is the initial treatment for this specific injury; subsequent care would use a different seventh character.
• Distinguish corrosion from thermal burns; this code is specifically for chemical-induced injuries.
