L249 - Skin irritation and inflammation caused by direct contact with an irritating substance, but the specific cause is not identified

International Classification of Diseases

Last updated: 3/24/2026

What is a ICD-10 Code?

ICD-10 (International Classification of Diseases, 10th Revision) codes are used to classify and code all diagnoses, symptoms, and procedures recorded in association with hospital care. These codes provide a standardized way to track health conditions and their treatment outcomes.

Detailed Description

This code represents irritant contact dermatitis where the skin has become red, inflamed, itchy, or developed a rash due to direct contact with an irritating substance (like chemicals, soaps, or other materials), but the healthcare provider has not specified or identified the exact substance that caused the reaction. Unlike allergic contact dermatitis, this type occurs from direct chemical damage to the skin rather than an immune system response.

Additional Information

This is a diagnostic code used when the cause of irritant contact dermatitis cannot be determined or is not specified. Treatment typically focuses on symptom management and avoiding further exposure to potential irritants.
