Corrosion of second degree of unspecified wrist, init encntr

This code signifies a second-degree chemical burn affecting an unspecified wrist. This type of injury involves damage to the epidermis and dermis, characterized by blistering, pain, and redness, but typically without full-thickness skin destruction. The "initial encounter" indicates that the patient is receiving active treatment for this specific injury.

Apply this code when documenting a patient presenting for the first time with a second-degree chemical burn to the wrist, where the specific wrist (left or right) is not documented. This is appropriate for initial evaluations, emergency department visits, or the first instance of treatment for this corrosion.

• Ensure the documentation clearly specifies a second-degree burn and a chemical etiology (corrosion).
• Only use this code if the laterality of the wrist is truly unspecified in the medical record. If left or right is documented, a more specific code should be chosen.
• The "A" suffix indicates an initial encounter; subsequent care for this same injury will require different seventh characters (e.g., D for subsequent, S for sequela).
