Poisoning by antirheumatics, NEC, self-harm, subs

This code signifies a poisoning event resulting from the deliberate self-administration of antirheumatic medications not classified elsewhere. It indicates that the patient is receiving follow-up care for the sequelae of this intentional overdose, rather than the initial presentation. The poisoning is a consequence of a purposeful act to harm oneself.

Apply this code when a patient presents for ongoing treatment, monitoring, or management of complications arising from a prior intentional overdose of an antirheumatic drug. This includes follow-up appointments for organ damage, psychiatric evaluation, or medication adjustments related to the poisoning. It is appropriate for any encounter after the initial acute treatment phase.

• Always use in conjunction with an external cause code (e.g., X60-X69) to specify the intent and circumstances of the poisoning.
• Ensure documentation clearly states "intentional self-harm" and that the encounter is "subsequent" to the initial treatment.
• Verify the specific antirheumatic agent involved, as more specific codes may exist if the drug is classifiable elsewhere.
