The code is not specific and is NOT valid for the year 2024 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Specific Coding Applicable to Heatstroke and sunstroke

Non-specific codes like T67.0 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for heatstroke and sunstroke:

  • T67.01 for Heatstroke and sunstroke - NON-BILLABLE CODE

  • Use T67.01XA for initial encounter - BILLABLE CODE

  • Use T67.01XD for subsequent encounter - BILLABLE CODE

  • Use T67.01XS for sequela - BILLABLE CODE

  • T67.02 for Exertional heatstroke - NON-BILLABLE CODE

  • Use T67.02XA for initial encounter - BILLABLE CODE

  • Use T67.02XD for subsequent encounter - BILLABLE CODE

  • Use T67.02XS for sequela - BILLABLE CODE

  • T67.09 for Other heatstroke and sunstroke - NON-BILLABLE CODE

  • Use T67.09XA for initial encounter - BILLABLE CODE

  • Use T67.09XD for subsequent encounter - BILLABLE CODE

  • Use T67.09XS for sequela - BILLABLE CODE

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

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.
