Toxic effect of detergents, undetermined, initial encounter

This code signifies a harmful reaction to a detergent where the specific intent (e.g., accidental, intentional self-harm, assault) is not documented. It indicates that the patient is in the acute phase of treatment for this toxic effect.

Apply this code when a patient presents with symptoms of poisoning or adverse effects due to exposure to a detergent, and the medical record does not specify whether the exposure was accidental, intentional, or due to assault. This is appropriate for the initial visit or admission for this specific toxic event.

• Ensure documentation clearly states "detergent" as the substance involved.
• Only use the "A" seventh character for the very first encounter for this specific toxic effect.
• If the intent of the exposure is later determined, a more specific T55.1X_ code should be used for subsequent encounters.
