2025 ICD-10-CM code W89
(Active) Effective Date: N/A Revision Date: N/A Deletion Date: N/A External causes of morbidity - Exposure to electric current, radiation and extreme ambient air temperature and pressure Chapter 20: External causes of morbidity Feed
Exposure to man-made visible and ultraviolet light, including welding arc light.
Modifiers do not apply to ICD-10 codes.
Medical necessity for treatment will be determined by the specific health condition caused by the exposure to light.The documentation should justify the medical necessity of any treatment provided, according to payer guidelines.
The clinical responsibility depends on the specific condition resulting from the exposure to man-made visible and ultraviolet light. This could involve various specialties, depending on the nature and severity of the injury or illness.Examples include ophthalmology, dermatology, or emergency medicine.

In simple words: This code is for when someone is hurt or gets sick because of exposure to bright, artificial light, like from welding.It's not the main diagnosis, but an extra code to show what caused the problem.
This ICD-10-CM code classifies exposure to man-made visible and ultraviolet light.It specifically includes exposure to welding arc light.This code should be used as a secondary code to indicate the cause of an injury or other health condition, and is not to be used as a primary diagnosis.It should be used in conjunction with a code from another chapter specifying the nature of the condition resulting from the exposure. The seventh character (A, D, or S) should be added to specify the encounter (initial, subsequent, or sequela).
Example 1: A welder experiences eye irritation and temporary vision impairment due to prolonged exposure to welding arc light.The primary diagnosis would be the eye condition (e.g., conjunctivitis), with W89 as a secondary code to indicate the cause., A construction worker suffers from sunburn after working outdoors under intense, artificial lighting.The primary diagnosis would be sunburn, and W89 would be used as a secondary code., A photographer develops skin irritation due to prolonged exposure to high-intensity studio lighting. The primary diagnosis is the skin condition, and W89 is used as the secondary code to illustrate the cause of the skin condition.
Documentation should include details of the exposure (type of light source, duration, intensity, protective measures used), the symptoms experienced, a diagnosis of the resulting health condition, and any treatment provided.
** This code is part of Chapter 20, which is used to report external causes of morbidity.These codes are never the principal diagnosis but are supplementary codes that provide additional information about the circumstances surrounding an injury or illness.
