Frostbite with tissue necrosis of left hand, init encntr

This code signifies frostbite affecting the left hand that has progressed to tissue death (necrosis). This indicates a severe form of cold injury where the tissue has been irreversibly damaged. The "initial encounter" designation means this code is used for the first time the patient is receiving active treatment for this specific frostbite injury.

Assign this code when documentation clearly states frostbite of the left hand with evidence of tissue necrosis, such as gangrene, mummification, or non-viable tissue. This is appropriate for the initial visit or admission where the frostbite is being actively managed. Subsequent encounters for the same injury would use a different seventh character.

• Ensure documentation specifies "left hand" and confirms tissue necrosis.
• Verify the encounter is indeed the initial treatment for this specific frostbite injury.
• Do not use for superficial frostbite or frostbite without documented tissue necrosis.
