Poisoning by loop diuretics, undetermined, initial encounter

This code signifies an adverse event resulting from the ingestion or exposure to loop diuretics, where the intent (accidental, intentional self-harm, assault) cannot be determined. The patient is in the initial phase of treatment for the poisoning, experiencing the acute effects of the substance.

Apply this code when a patient presents with symptoms of loop diuretic toxicity, and the medical record explicitly states that the circumstances surrounding the poisoning are unknown or undetermined. This is appropriate for the first encounter where the poisoning is being evaluated and treated.

• Ensure documentation clearly states "undetermined" intent for the poisoning.
• Always use this code with an external cause code (e.g., Y10-Y19) to specify the undetermined intent.
• Do not use this code if the intent (accidental, intentional self-harm, assault) is known or suspected.
