Poisoning by unsp narcotics, intentional self-harm, sequela

This code signifies a long-term consequence or complication arising from a previous act of intentional self-poisoning involving an unspecified narcotic substance. It indicates that the acute phase of the poisoning has passed, and the patient is now experiencing residual effects directly attributable to that event. These sequelae can manifest in various organ systems depending on the narcotic and the severity of the initial poisoning.

This code is appropriate when documenting chronic health issues, organ damage, or persistent neurological deficits that are a direct result of a past intentional self-harm attempt with an unspecified narcotic. It should be used after the acute poisoning has been treated and the patient is presenting for follow-up care related to these lasting effects. Do not use for the initial acute poisoning event.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., chronic liver failure, neurological deficit).
• Ensure documentation clearly links the current condition to a past intentional self-harm narcotic poisoning.
• If the specific narcotic is known, a more precise T40.6x- code should be used instead of "unspecified."
