Poisn by oth prim sys and hematolog agents, assault, sequela

This code indicates a long-term consequence or complication resulting from an intentional poisoning by a systemic or hematological agent, where the poisoning was an act of assault. It signifies that the acute phase of the poisoning has passed, but the patient continues to experience residual effects directly attributable to the original event.

Use this code when documenting chronic conditions, permanent disabilities, or persistent symptoms that are a direct result of a past assaultive poisoning by substances affecting the body's systems or blood. This applies to follow-up encounters for ongoing management of these sequelae, not the initial acute poisoning event.

• Always sequence this sequela code after the code(s) for the specific residual condition(s) being treated.
• Ensure documentation clearly links the current condition to a past assaultive poisoning by a systemic or hematological agent.
• Do not use for acute poisoning events; those require acute poisoning codes with the appropriate seventh character.
