Poisoning by loop diuretics, intentional self-harm, init

This code signifies a patient presenting with adverse effects resulting from the deliberate self-administration of loop diuretics, such as furosemide or bumetanide, with the intent to cause harm. The patient is in the initial phase of receiving active treatment for this poisoning.

Apply this code when documenting the initial encounter for a patient admitted to the emergency department or inpatient setting due to an overdose of loop diuretics, where the medical record clearly indicates the act was intentional self-harm. This includes cases where the patient explicitly states suicidal intent or the circumstances strongly suggest it.

• Ensure documentation explicitly states "intentional self-harm" or "suicide attempt" in relation to the loop diuretic ingestion.
• This "A" seventh character is only for the initial encounter for active treatment of the poisoning.
• Always code the specific loop diuretic if known, using an additional code from T36-T50 if applicable, to provide greater specificity.
