Code Classification

  • Injury, poisoning and certain other consequences of external causes
    (S00–T88)
    • Other and unspecified effects of external causes
      (T66-T78)
      • Effects of heat and light
        (T67)

T67.01XA is a billable diagnosis code used to specify a medical diagnosis of heatstroke and sunstroke, 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.

T67.01XA is an initial encounter code, includes a 7th character and should be used while the patient is receiving active treatment for a condition like heatstroke and sunstroke. 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.

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

  • Heat exposure
  • Heat stroke
  • Hyperthermia
  • Hyperthermia
  • Sunstroke

Clinical Classification

Clinical Information

  • Drug Fever

    drug-induced fever.

  • Hyperthermia

    an abnormal elevation of body temperature, usually as a result of inability to regulate core body temperature due to non-pathologic factors.

  • Hyperthermia, Induced

    abnormally high temperature intentionally induced in living things regionally or whole body. it is most often induced by radiation (heat waves, infra-red), ultrasound, or drugs.

  • Malignant Hyperthermia

    rapid and excessive rise of temperature accompanied by muscular rigidity following general anesthesia.

  • Sunstroke

    heat stroke caused by exposure to the sun. it is characterized by dangerously high body temperature; red, hot skin; delusions; convulsions; or coma. it can be a life-threatening emergency and is most common in infants and the elderly.

  • Heat Stroke

    a condition caused by the failure of body to dissipate heat in an excessively hot environment or during physical exertion in a hot environment. contrast to heat exhaustion, the body temperature in heat stroke patient is dangerously high with red, hot skin accompanied by delusions; convulsions; or coma. it can be a life-threatening emergency and is most common in infants and the elderly.

Coding Guidelines

The appropriate 7th character is to be added to each code from block Effects of heat and light (T67). Use the following options for the aplicable episode of care:

  • A - initial encounter
  • D - subsequent encounter
  • S - sequela

Replacement Code

T6701XA replaces the following previously assigned ICD-10-CM code(s):

  • T67.0XXA - Heatstroke and sunstroke, initial encounter

Patient Education


Heat Illness

Your body normally cools itself by sweating. During hot weather, especially when it is very humid, sweating just isn't enough to cool you off. Your body temperature can rise to dangerous levels and you can develop a heat illness.

Most heat illnesses happen when you stay out in the heat too long. Exercising and working outside in high heat can also lead to heat illness. Older adults, young children, and those who are sick or overweight are most at risk. Taking certain medicines or drinking alcohol can also raise your risk.

Heat-related illnesses include:

  • Heat stroke - a life-threatening illness in which body temperature may rise above 106 °F (41 °C) in minutes. Symptoms include dry skin, a rapid, strong pulse, dizziness, nausea, and confusion. If you see any of these signs, get medical help right away.
  • Heat exhaustion - an illness that can happen after several days of exposure to high temperatures and not enough fluids. Symptoms include heavy sweating, rapid breathing, and a fast, weak pulse. If it is not treated, it can turn into heat stroke.
  • Heat cramps - muscle pains or spasms that happen during heavy exercise. You usually get them in your abdomen, arms, or legs.
  • Heat rash - skin irritation from excessive sweating. It is more common in young children.

You can lower your risk of heat illness by drinking fluids to prevent dehydration, replacing lost salt and minerals, and limiting your time in the heat.

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.
