Toxic effect of strychnine and its salts, undet, sequela

This code signifies the long-term, residual effects resulting from a past exposure to strychnine or its derivatives, where the intent of the poisoning (e.g., accidental, intentional self-harm, assault) could not be determined. These sequelae can manifest as chronic neurological issues, organ damage, or other persistent health problems directly attributable to the prior toxic event.

Apply this code when documenting conditions that are a direct consequence of a previous strychnine poisoning, and the original incident's intent was not definitively established. This is used for follow-up care and management of chronic conditions stemming from the toxic exposure, not for the acute poisoning event itself.

• Always sequence this sequela code after the code for the specific residual condition being treated.
• Ensure documentation clearly links the current condition to a past strychnine exposure with an undetermined intent.
• Do not use this code for acute poisoning or when the intent of the poisoning is known (e.g., accidental, intentional).
