Poisn by oth drug aff the autonm nervous sys, asslt, sequela

This code signifies a long-term or residual effect resulting from a deliberate act of poisoning by a drug that primarily impacts the autonomic nervous system. The initial poisoning event was an assault, and the patient is now presenting with ongoing health issues directly attributable to that past event.

This code is appropriate for documenting chronic conditions, permanent disabilities, or persistent symptoms that are a direct consequence of a past assault involving a drug affecting the autonomic nervous system. Examples include ongoing dysautonomia, persistent cardiac arrhythmias, or chronic gastrointestinal motility issues stemming from such an event.

• Always sequence this code after the code(s) for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a past poisoning by assault.
• Verify the drug involved primarily affects the autonomic nervous system to justify this specific category.
