Poisn by unsp drugs aff the autonm nrv sys, asslt, sequela

This code signifies a long-term consequence or complication arising from an intentional overdose or exposure to an unknown medication that primarily impacts the body's involuntary functions, such as heart rate, digestion, and breathing. The initial poisoning event occurred in the past, and the patient is now presenting with residual effects.

Apply this code when documenting a patient's current health issues that are directly attributable to a past assault involving an unspecified drug affecting the autonomic nervous system. This is appropriate for follow-up care, rehabilitation, or management of chronic conditions resulting from such an event, after the acute phase of the poisoning has resolved.

• Always sequence this code after the code(s) for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a past assaultive poisoning by an unspecified autonomic drug.
• Avoid using this code for acute poisoning events; it is specifically for sequelae.
