Poisoning by opium, assault, sequela

This code indicates a long-term consequence or complication resulting from an intentional poisoning by opium, where the poisoning was inflicted by another person. It signifies that the acute phase of the opium poisoning has passed, and the patient is now experiencing residual effects. These sequelae could be physical, neurological, or psychological in nature.

Use this code when documenting a patient presenting with a chronic condition or lasting impairment directly attributable to a past assault involving opium poisoning. This applies to follow-up encounters where the focus is on managing the persistent effects, rather than the immediate treatment of the acute poisoning event. Examples include chronic pain, organ damage, or neurological deficits stemming from the original assault.

• 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 opium poisoning by assault.
• Do not use for acute poisoning events; those require codes from the initial encounter or subsequent encounter categories.
