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

This code signifies a deliberate act of self-poisoning using antineoplastic (chemotherapy) or immunosuppressive medications. It indicates that the patient intentionally ingested, injected, or otherwise administered these drugs to themselves with the intent to cause harm. This code is specifically for the initial presentation of such an event.

Use this code when a patient presents to an emergency department or clinic after intentionally overdosing on chemotherapy drugs or medications used to suppress the immune system. This applies to the first time the patient is seen for this particular self-harm attempt. Examples include a patient admitting to taking extra doses of their methotrexate or cyclosporine with suicidal intent.

• Always assign an additional code for the specific antineoplastic or immunosuppressive drug involved (T36-T50).
• Do not use this code for accidental poisonings; refer to codes for unintentional poisoning (e.g., T45.1X1-).
• Ensure documentation clearly states "intentional self-harm" and "initial encounter" to support the use of this specific code.
