Poisoning by antirheumatics, NEC, self-harm, init

This diagnosis code signifies an intentional overdose or self-poisoning event involving antirheumatic medications not categorized elsewhere. The patient deliberately ingested or administered these substances with the intent to cause harm to themselves. This code is specifically for the initial phase of treatment for this poisoning.

Apply this code when a patient presents to an emergency department or clinic following a deliberate self-harm attempt using antirheumatic drugs. This includes cases where the patient explicitly states intent or when clinical evidence strongly suggests intentional ingestion. It is appropriate for the first encounter for this specific poisoning event.

• Ensure documentation clearly supports intentional self-harm, not accidental or therapeutic misadventure.
• Verify the substance involved is an antirheumatic agent and not classified under a more specific poisoning code.
• Only use the "A" (initial encounter) seventh character for the first time the patient is seen for this specific poisoning.
