Poisoning by unspecified psychotropic drug, assault, sequela

This code signifies a long-term health condition or complication arising from a poisoning event involving an unspecified psychotropic drug, where the poisoning was intentionally inflicted by another person. It indicates that the acute phase of the poisoning has passed, and the patient is now experiencing residual effects.

Apply this code when documenting a sequela (e.g., chronic organ damage, neurological deficits, psychiatric disorders) directly attributable to a past assault involving an unknown psychotropic substance. This code is appropriate for follow-up encounters after the initial poisoning has been treated, and the patient is being managed for lasting consequences.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a past poisoning by assault.
• Verify that the psychotropic drug involved was truly unspecified in the medical record.
