Poisoning by loop diuretics, assault, initial encounter

This code signifies a patient presenting with adverse effects resulting from the intentional administration of a loop diuretic by another person with intent to harm. The patient is in the acute phase of this poisoning, receiving initial treatment and evaluation. This includes symptoms such as severe dehydration, electrolyte imbalances (e.g., hypokalemia, hyponatremia), hypotension, and potential renal dysfunction.

Apply this code when documentation clearly indicates a patient has been poisoned by a loop diuretic due to an assault. This is appropriate for the initial visit or encounter where the poisoning is first diagnosed and treated. Examples include a patient brought to the emergency department after being forcibly given a large dose of furosemide by an assailant.

• Ensure the documentation explicitly states "assault" or "intentional harm by another" as the cause of the poisoning.
• Verify that the substance involved is specifically a loop diuretic (e.g., furosemide, bumetanide, torsemide).
• Confirm this is the initial encounter for this specific poisoning event; subsequent encounters would use a different seventh character.
