Poisoning by antineopl and immunosup drugs, assault, sequela

This code signifies a long-term complication or residual effect resulting from a deliberate act of poisoning with antineoplastic (chemotherapy) or immunosuppressive medications. The initial poisoning event occurred in the past, and the patient is now experiencing persistent health issues directly attributable to that assault.

Apply this code when documenting a patient presenting with chronic organ damage, neurological deficits, or other lasting adverse effects that are a direct consequence of a past intentional overdose or administration of antineoplastic or immunosuppressive drugs by another person. This code is appropriate for follow-up visits and ongoing management of these sequelae.

• Always sequence this code after the code(s) for the specific sequela being treated (e.g., chronic kidney disease, neuropathy).
• Ensure documentation clearly links the current condition to a past poisoning by antineoplastic/immunosuppressive drugs and specifies the assault intent.
• Do not use for acute poisoning events; this code is exclusively for residual effects.
