T34.02XA is a billable diagnosis code used to specify a medical diagnosis of frostbite with tissue necrosis of nose, initial encounter. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

T34.02XA is an initial encounter code, includes a 7th character and should be used while the patient is receiving active treatment for a condition like frostbite with tissue necrosis of nose. According to ICD-10-CM Guidelines an "initial encounter" doesn't necessarily means "initial visit". The 7th character should be used when the patient is undergoing active treatment regardless if new or different providers saw the patient over the course of a treatment. The appropriate 7th character codes should also be used even if the patient delayed seeking treatment for a condition.

Patient Education


Frostbite

Frostbite is an injury to the body that is caused by freezing. It most often affects the nose, ears, cheeks, chin, fingers, or toes. Frostbite can permanently damage the body, and severe cases can lead to amputation.

If you have frostbite, the skin in that area may turn white or grayish-yellow. It may feel firm or waxy when you touch it. The area will also feel numb.

If you have symptoms of frostbite, seek medical care. But if immediate medical care isn't available, here are steps to take:

  • Get into a warm room as soon as possible.
  • If possible, do not walk on frostbitten feet or toes. Walking increases the damage.
  • Put the affected area in warm - not hot - water.
  • You can also warm the affected area using body heat. For example, use your armpit to warm frostbitten fingers.
  • Don't rub the frostbitten area with snow or massage it at all. This can cause more damage.
  • Don't use a heating pad, heat lamp, or the heat of a stove, fireplace, or radiator for warming. Since frostbite makes an area numb, you could burn it.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
