Corrosion of second degree of right foot, initial encounter

This code signifies a second-degree chemical burn affecting the right foot. This type of injury involves damage to the epidermis and dermis, characterized by blistering, redness, and significant pain, resulting from exposure to a corrosive substance.

Apply this code when documentation clearly indicates a chemical burn of the second degree on the patient's right foot. This is appropriate for the initial visit or encounter for this specific injury, where active treatment is being rendered.

• Confirm the laterality (right foot) and the degree of the corrosion (second degree) from the physician's documentation.
• Ensure the encounter is indeed the "initial encounter" for this specific injury; subsequent encounters will require a different seventh character.
• Always code the external cause of the corrosion (e.g., exposure to acid, alkali) in addition to this diagnosis code.
