Corrosion of second degree back of left hand, init encntr

This code signifies a second-degree chemical burn affecting the back of the left hand. It indicates damage extending through the epidermis and into the dermis, characterized by blistering, pain, and redness, resulting from exposure to a corrosive substance.

Apply this code for initial encounters where a patient presents with a second-degree corrosion injury specifically located on the dorsal aspect of their left hand. This is appropriate for the first time the patient is seen for this particular injury.

• Ensure the documentation specifies "corrosion" (chemical burn) rather than a thermal burn.
• Verify the exact location is the "back of the left hand" and the depth is "second degree."
• Confirm this is the initial encounter for this specific injury to use the "A" seventh character.
