Adverse effect of loop diuretics, initial encounter

This diagnosis code signifies an undesirable or harmful reaction experienced by a patient due to the therapeutic use of a loop diuretic, such as furosemide or bumetanide. This adverse effect occurred during the initial period of treatment or encounter for the specific reaction.

Apply this code when a patient presents with symptoms or conditions directly attributable to the intended use of a loop diuretic, and this is the first time the patient is being seen or treated for this particular adverse reaction. Examples include electrolyte imbalances (e.g., hypokalemia, hyponatremia), dehydration, or ototoxicity that developed after starting or taking a prescribed loop diuretic.

• Always sequence this code after the code for the specific adverse effect (e.g., E87.6 for hypokalemia).
• Ensure documentation clearly states the patient is experiencing an adverse effect, not poisoning or underdosing.
• Verify that this is indeed the initial encounter for the adverse effect, as subsequent encounters would use a different seventh character.
