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

This code signifies the long-term effects or complications arising from a past poisoning event involving immune checkpoint inhibitors or other immunostimulant drugs, specifically when the poisoning was due to an intentional act of harm by another person. It indicates that the patient is now experiencing residual health problems directly attributable to that assault.

Apply this code when documenting a patient presenting with chronic or permanent conditions, such as organ damage, neurological deficits, or persistent autoimmune reactions, that are a direct result of a previous poisoning by immune checkpoint inhibitors or immunostimulant drugs. The original poisoning event must have been determined to be an assault.

• 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 the specified drug classes and explicitly states the poisoning was an assault.
• Do not use for acute poisoning events; this code is exclusively for sequelae.
