Poisoning by unsp antipsychot/neurolept, assault, sequela

This code indicates a long-term health problem or complication resulting from a past poisoning event involving an unspecified antipsychotic or neuroleptic medication, where the poisoning was intentionally inflicted by another person. The patient is no longer in the acute phase of the poisoning, but is experiencing residual effects.

This code is appropriate for documenting chronic conditions, permanent disabilities, or ongoing medical issues directly attributable to a previous assault by an unspecified antipsychotic or neuroleptic. Examples include persistent neurological deficits, organ damage, or psychiatric sequelae that have stabilized but continue to require management.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic encephalopathy, kidney failure).
• Ensure documentation clearly links the current condition to a past poisoning by an unspecified antipsychotic/neuroleptic and specifies the assault intent.
• Do not use this code for acute poisoning events; instead, use the appropriate acute poisoning code with the 7th character for initial or subsequent encounter.
