Toxic effect of lacrimogenic gas, undetermined, init encntr

This code signifies an adverse health effect resulting from exposure to a lacrimogenic gas, such as tear gas, where the intent (accidental, intentional self-harm, assault) of the exposure is not documented. The patient is in the acute phase of treatment for this toxic effect.

Use this code for patients presenting with symptoms like eye irritation, respiratory distress, or skin burns following exposure to tear gas, when the circumstances surrounding the exposure are unknown or not specified in the medical record. This applies to the initial visit for this specific toxic effect.

• Ensure documentation clearly indicates the toxic agent was a lacrimogenic gas.
• Only use the "A" seventh character for the first encounter for treatment of this condition.
• If the intent of exposure is known (e.g., accidental, assault), a more specific T59.3X1-, T59.3X2-, or T59.3X3- code should be used.
