Poisn by immune chkpt inhibtr/immunostim drugs, asslt, subs

This code signifies a poisoning event specifically caused by immune checkpoint inhibitors or other immunostimulant medications, resulting from an assault. It indicates that the patient is receiving active treatment for the toxic effects of the drug, not for the initial injury itself. This diagnosis points to a deliberate act by another party to cause harm using these specific pharmaceutical agents.

Use this code when a patient presents with adverse effects from immune checkpoint inhibitors or immunostimulant drugs, and the medical record clearly documents that the exposure was due to an intentional act of assault. This code is appropriate for subsequent encounters where the patient is still undergoing treatment for the poisoning. It should be applied when the focus of care is managing the drug toxicity, not the initial assault.

• Ensure documentation explicitly states "assault" as the cause of poisoning.
• Verify the specific drug class involved is an immune checkpoint inhibitor or immunostimulant.
• Confirm this is a subsequent encounter for treatment of the poisoning, not the initial presentation.
