Toxic effect of lacrimogenic gas, undetermined, sequela

This code signifies a delayed or residual health issue resulting from exposure to lacrimogenic gas, such as tear gas, where the intent of exposure is unknown. It indicates that the acute phase of the toxic effect has passed, but the patient continues to experience related symptoms or conditions. This could encompass chronic respiratory problems, dermatological issues, or persistent ocular irritation.

Apply this code when documenting a follow-up visit for a patient experiencing ongoing health problems directly attributable to a past, undetermined exposure to lacrimogenic gas. This is appropriate for conditions that manifest weeks, months, or even years after the initial exposure. Use when the initial acute toxic effects have resolved, but the sequelae require continued medical management.

• Ensure documentation clearly links the current condition to a past lacrimogenic gas exposure.
• This "S" seventh character indicates a sequela, meaning it's for complications or conditions arising from the initial injury or poisoning.
• Do not use for acute exposures; those require different seventh characters.
