ICD-10-CM Code W93.8XXS: Exposure to other excessive cold of man-made origin, sequela

ICD-10-CM code W93.8XXS classifies a sequela resulting from exposure to other excessive cold of man-made origin. The code is active for the 2026 version and falls under the parent category W93.8. It is semantically classified as an injury or poisoning concept, and public health sources detail the physiological impacts of cold exposure. 1 2

Plain-language overview

ICD-10-CM code W93.8XXS is an active terminology concept representing the residual effects of exposure to other excessive cold of man-made origin, with a semantic type of injury or poisoning. 1

What this code represents

Code W93.8XXS is a child concept of W93.8, which specifically denotes exposure to other excessive cold of man-made origin, and the seventh character S indicates a sequela condition. 1

Clinical context

Physiological responses to cold exposure include sympathetically-mediated vasoconstriction in the extremities, which reduces peripheral blood flow and can lead to tissue necrosis or non-freezing cold injuries. 2

Severe stages of cold injury can leave a patient with intense sensitivity to repeated cold exposure and neuropathic pain, alongside an increased vulnerability to future cold exposure. 3

Documentation considerations

The official terminology record for W93.8XXS assigns the semantic type of injury or poisoning and classifies the concept as a sequela of exposure to other excessive cold of man-made origin. 1

Coverage and utilization context

The code W93.8XXS appears in external coding reference lists alongside other environmental exposure codes, such as exposure to prolonged high air pressure. 4

What the sources add

While the terminology record establishes the official code hierarchy and active status, clinical sources provide operational context by detailing the physiological injuries and sensitivities caused by cold exposure. 1 2 3

A comparison of sources shows that the terminology record defines the code structure, whereas clinical literature describes the actual physical impairments, such as decreased manual dexterity and motor function. 1 2
