Corrosion of second degree of right toe(s) (nail), subs

This code signifies a second-degree chemical burn affecting the toe(s) or toenail(s) on the patient's right foot. This type of injury involves damage to the epidermis and dermis, characterized by blistering, pain, and redness.

This code is appropriate for follow-up visits where a patient is receiving ongoing treatment or monitoring for a previously diagnosed second-degree corrosion of the right toe(s) or nail. It would be used after the initial encounter for the injury.

• Ensure the documentation specifies "corrosion" (chemical burn) rather than a thermal burn.
• Verify the laterality is explicitly "right" and the encounter is "subsequent."
• Confirm the depth of the burn is clearly documented as "second degree."
