Poisoning by saluretics

This code signifies an adverse reaction or overdose specifically due to diuretics that promote the excretion of sodium and chloride (saluretics). This can manifest as electrolyte imbalances (e.g., hypokalemia, hyponatremia), dehydration, hypotension, or renal dysfunction. It represents an unintended or harmful effect from the use of these medications.

Apply this code when documentation clearly indicates poisoning or an adverse effect from a saluretic agent, such as furosemide, hydrochlorothiazide, or torsemide. This is appropriate for cases of accidental overdose, intentional self-harm, or adverse drug reactions where the drug's effect is toxic rather than therapeutic. Supporting documentation should specify the drug involved and the resulting clinical presentation.

• Always sequence this code as a secondary diagnosis following the code for the specific manifestation of the poisoning (e.g., hypokalemia).
• Distinguish from adverse effects of other diuretic classes (e.g., potassium-sparing diuretics) which have different poisoning codes.
• Ensure the documentation specifies "poisoning" or "adverse effect" rather than a therapeutic effect or simple side effect.
