Frostbite with tissue necrosis of right hand, init encntr

This code signifies severe cold injury to the right hand, characterized by the death of tissue (necrosis). This indicates a deep and serious frostbite injury that has progressed beyond superficial damage, affecting the cellular structure of the hand.

Apply this code when a patient presents with a confirmed diagnosis of frostbite to the right hand, and clinical documentation clearly indicates the presence of tissue necrosis. This is appropriate for the initial visit or encounter where the frostbite is being evaluated and treated for the first time.

• Ensure documentation specifies "right hand" and confirms tissue necrosis.
• Verify this is the initial encounter for this specific frostbite injury. Subsequent encounters would require a different seventh character.
• Do not use for frostbite without necrosis or for other body sites.
