Toxic effect of lacrimogenic gas, accidental, sequela

This code signifies a long-term, residual health problem resulting from an accidental exposure to lacrimogenic gas. It's used when the initial acute effects have passed, but the patient continues to experience related symptoms or conditions.

Apply this code for patients presenting with chronic respiratory issues, ocular damage, or dermatological conditions that are directly attributed to an unintentional exposure to tear gas or similar agents in the past. This is appropriate for follow-up visits addressing these persistent sequelae.

• Ensure documentation clearly links the current condition to a past, accidental lacrimogenic gas exposure.
• Always use in conjunction with a code for the specific manifestation (e.g., chronic conjunctivitis, asthma).
• The 7th character "S" indicates sequela, meaning it's for the late effects of the initial injury.
