Superficial frostbite of left foot, initial encounter

This code signifies damage to the skin and underlying tissues of the left foot caused by exposure to freezing temperatures, specifically limited to the superficial layers. It indicates the initial presentation of frostbite, where the skin may appear pale, waxy, or numb, but without blistering or deeper tissue involvement.

Apply this code for patients presenting with a new diagnosis of superficial frostbite affecting their left foot. This includes emergency department visits, urgent care encounters, or initial physician office visits for evaluation and treatment of the cold injury. It is appropriate when the patient has not received prior treatment for this specific frostbite episode.

• Ensure documentation specifies "superficial" and "left foot" to support this code.
• Confirm this is the first encounter for this specific frostbite injury; subsequent encounters will use a different seventh character.
• Look for documentation of symptoms like numbness, tingling, or skin discoloration without signs of tissue necrosis or blistering.
