2025 ICD-10-CM code W92
Exposure to excessive heat of man-made origin.
The 7th character of W92 indicates the encounter type (initial, subsequent, or sequela). This character should match the 7th character of the primary diagnosis code.
The medical necessity of using W92 is to provide additional information about the circumstances that led to the patient's condition. This data is valuable for injury research and prevention initiatives.
Clinicians should use this code as a secondary code to indicate the cause of a heat-related condition. The primary code should be the diagnosis of the condition itself (e.g., heat stroke, heat exhaustion).
In simple words: Exposure to too much heat from something made by humans.
Exposure to excessive heat of man-made origin.
Example 1: A patient presents with heat stroke after working in a factory with inadequate ventilation and cooling systems. The primary diagnosis would be the heat stroke code, and W92 would be used as a secondary code to indicate the cause of the heat stroke., A firefighter sustains burns while fighting a fire in a building. The primary diagnosis would be the burn code, and W92 would be added to indicate exposure to the excessive heat of the fire., A baker develops heat exhaustion after spending hours in a hot kitchen with ovens constantly on. The heat exhaustion diagnosis is the primary code, while W92 would be used as a secondary code to indicate the source of the heat exposure.
Documentation should clearly state the source of the heat exposure and its relationship to the patient's condition. Details such as the environment, duration of exposure, and symptoms should be included.
** This code excludes exposure to natural heat (X30). Reporting of external cause codes is not mandatory nationally, but it is encouraged for injury research and prevention.Specific payers or states may have their own reporting requirements.
