Poisoning by loop diuretics, intentional self-harm, subs

This code signifies a patient presenting for follow-up care related to a previous self-inflicted overdose of loop diuretics. It indicates that the initial poisoning was a deliberate act of self-harm, and the current encounter is for ongoing management or complications arising from that event.

Use this code for subsequent visits where a patient is being treated for sequelae of a prior intentional loop diuretic overdose, such as electrolyte imbalances, kidney injury, or cardiac arrhythmias. It is appropriate for encounters like medication adjustments, monitoring of organ function, or mental health follow-up directly related to the self-harm attempt.

• Ensure documentation clearly states the poisoning was intentional self-harm and that this is not the initial encounter.
• Always code with an external cause code (X-code) to specify the intent and circumstances of the poisoning.
• Do not use for initial treatment of the acute poisoning; a different 7th character would be appropriate for the initial encounter.
