Frostbite with tissue necrosis of left toe(s), init encntr

This code signifies frostbite affecting one or more toes on the left foot, where the tissue has died (necrosis) as a result of the cold injury. This indicates a severe form of frostbite, beyond superficial damage, requiring significant medical intervention.

Assign this code when a patient presents with a new diagnosis of severe frostbite to the left toes, characterized by non-viable tissue. This would be appropriate for the initial hospital admission or first outpatient visit for this specific frostbite injury.

• Ensure documentation clearly specifies "left" toe(s) and the presence of tissue necrosis.
• Verify this is the patient's initial encounter for this particular frostbite episode.
• Do not use for superficial frostbite or frostbite without documented tissue death.
