Toxic effect of other specified substances, assault, sequela

This code signifies a long-term or residual health effect resulting from a toxic exposure to a specified substance, where the exposure was intentionally inflicted by another person (assault). It indicates that the acute phase of the poisoning has passed, but the patient continues to experience related medical issues.

Apply this code when documenting chronic or ongoing health problems directly attributable to a past assault involving a toxic substance. This includes conditions like persistent organ damage, neurological deficits, or other sequelae that manifest after the initial acute toxic event has resolved.

• Always use in conjunction with a code identifying the specific sequela (e.g., chronic kidney disease, peripheral neuropathy).
• Requires documentation clearly linking the current condition to a past toxic assault.
• Do not use for acute poisoning; this code is exclusively for the late effects.
