Poisoning by antineopl and immunosup drugs, self-harm, subs

This code signifies a patient presenting with adverse effects from antineoplastic or immunosuppressive medications, where the ingestion or administration was a deliberate act of self-harm. The patient is currently receiving active treatment for the poisoning or its complications, or is in the recovery phase following initial treatment.

Apply this code when documenting a patient who has intentionally overdosed on chemotherapy drugs, transplant medications, or other immune-modulating agents, and is now in a subsequent phase of care. This includes follow-up visits for ongoing management of organ damage, electrolyte imbalances, or other sequelae directly resulting from the self-poisoning.

• Ensure the documentation clearly supports intentional self-harm and not accidental or therapeutic misadventure.
• Verify that the encounter is indeed "subsequent" and not the initial presentation for the poisoning.
• Always code the specific antineoplastic or immunosuppressive drug involved, if known, as an additional code.
