Toxic effect of lacrimogenic gas, accidental, init

This code signifies an adverse health effect resulting from unintentional exposure to a lacrimogenic (tear-producing) gas. This typically involves symptoms such as eye irritation, tearing, respiratory distress, and skin irritation due to accidental contact with substances like tear gas or pepper spray.

Apply this code when documenting a patient presenting with symptoms following an accidental exposure to a lacrimogenic agent. This is appropriate for initial evaluations and treatments of acute injuries or reactions from an unintentional encounter. Examples include bystanders caught in a crowd control situation or accidental discharge of a personal defense spray.

• Ensure documentation clearly states the exposure was accidental and not intentional self-harm or assault.
• Always use the appropriate seventh character for the encounter (A for initial, D for subsequent, S for sequela).
• Consider additional codes for specific symptoms or injuries sustained, such as chemical conjunctivitis (H10.81-) or chemical bronchitis (J68.0).
