Poisoning by loop diuretics, accidental, subs

This code signifies an accidental overdose or adverse reaction to a loop diuretic, such as furosemide or bumetanide, during a follow-up visit. The patient is experiencing ongoing effects or complications from the initial unintentional poisoning event.

Use this code when a patient presents for continued management, monitoring, or treatment of symptoms directly related to an accidental loop diuretic poisoning that occurred previously. This includes follow-up appointments for electrolyte imbalances, dehydration, or renal dysfunction stemming from the initial event.

• Ensure the encounter is for follow-up care, not the initial acute poisoning.
• Always sequence this code after the primary diagnosis describing the specific manifestation of the poisoning (e.g., dehydration, hypokalemia).
• Verify that the poisoning was unintentional; intentional poisonings require different codes.
