Adverse effect of loop [high-ceiling] diuretics, sequela

This code signifies a long-term or residual condition resulting from a past adverse reaction to loop diuretics. It indicates that the patient experienced an undesirable effect from medications like furosemide or torsemide, and this effect has now led to a permanent or chronic health issue.

Apply this code when documenting a chronic health problem directly attributable to a previous adverse effect of a loop diuretic. Examples include persistent electrolyte imbalances, permanent hearing loss (ototoxicity), or chronic kidney disease that developed as a sequela of acute kidney injury caused by the diuretic. This code is used after the acute adverse event has resolved, but its lasting consequences remain.

• Always sequence this code after the code for the specific sequela (e.g., H91.0- for ototoxic hearing loss).
• Ensure documentation clearly links the current chronic condition to a past adverse effect of a loop diuretic.
• Do not use this code for acute adverse effects; refer to the appropriate acute adverse effect code for the initial event.
