Superficial frostbite of left finger(s), initial encounter

This code signifies a first-degree frostbite injury affecting one or more fingers on the patient's left hand. Superficial frostbite involves freezing of the skin and subcutaneous tissue, typically presenting with numbness, white or mottled skin, and a waxy appearance, without blistering or tissue loss at this stage.

Apply this code for patients presenting with initial symptoms of superficial frostbite localized to the left fingers, such as after exposure to extreme cold. This is appropriate when the patient is receiving active treatment for the frostbite for the first time.

• Ensure documentation specifies "superficial" and "left finger(s)" for accurate code assignment.
• The "A" seventh character indicates an initial encounter for active treatment of the injury.
• Do not use this code if blistering, tissue necrosis, or deeper tissue involvement is documented; consider codes for deeper frostbite.
