Superficial frostbite of left toe(s), initial encounter

This code signifies a mild, non-blistering cold injury affecting the toes of the left foot. It involves damage to the superficial layers of skin and subcutaneous tissue, typically presenting with numbness, tingling, and a waxy appearance. The tissue remains soft and pliable upon palpation.

Apply this code for a patient presenting with their first episode of superficial frostbite specifically on the left toes. This is appropriate when the injury does not involve blistering or deeper tissue damage. It is used for the initial treatment and evaluation of the frostbite.

• Ensure documentation specifies "superficial" and "left toe(s)" to support this code.
• The "A" in the seventh character indicates an initial encounter for this condition.
• Do not use if blistering or tissue necrosis is present; those indicate deeper frostbite categories.
