Superficial frostbite of unspecified wrist, init encntr

This code signifies a superficial cold-induced injury to an unspecified wrist, characterized by numbness, tingling, and possibly white or pale skin, without blistering or tissue loss. It indicates the initial presentation and treatment of this type of frostbite.

Apply this code for patients presenting with a first-time diagnosis of mild frostbite affecting the wrist, where the specific left or right wrist is not documented. This is appropriate when the injury is limited to the skin surface without deeper tissue involvement.

• Ensure documentation specifies "superficial" and "wrist" and does not indicate blistering or deeper tissue damage.
• Only use the "A" seventh character for the initial encounter for treatment of this condition.
• If the laterality (left or right) of the wrist is documented, a more specific code should be selected.
