Corrosion of third degree of unspecified wrist, init encntr

This code signifies a full-thickness chemical burn (corrosion) affecting the entire skin layers and underlying tissue of an unspecified wrist. This type of injury results in significant tissue destruction, often appearing leathery or charred, and typically involves nerve damage, leading to a lack of sensation in the affected area.

Apply this code for a patient presenting with a third-degree chemical burn to the wrist, where the specific laterality (left or right) of the wrist is not documented. This code is appropriate for the initial treatment of such an injury, including emergency department visits or initial hospital admissions.

• Ensure documentation clearly specifies "corrosion" or "chemical burn" and "third degree."
• Only use this code when the laterality of the wrist is truly unspecified in the medical record.
• The "A" seventh character indicates an initial encounter for active treatment of the injury.
