Underdosing of antifungal antibiotics, sys used, sequela

This code signifies the long-term or residual effects resulting from the insufficient administration or cessation of systemically acting antifungal antibiotics. It indicates that a patient experienced a negative health outcome that is directly attributable to not receiving the appropriate dosage or duration of antifungal treatment. These sequelae can manifest after the acute phase of underdosing has passed.

Apply this code when documenting a condition or symptom that is a direct consequence of a past underdosing of systemic antifungal medication. This includes situations where a fungal infection recurred, became chronic, or led to organ damage due to inadequate treatment. It is used when the underdosing event itself is no longer active, but its lasting impact is being addressed.

• Always sequence this code after the code(s) for the specific sequela (e.g., chronic fungal infection, organ damage).
• This code is for the sequela of underdosing, not the active underdosing event itself.
• Ensure documentation clearly links the current condition to a past underdosing of systemic antifungal antibiotics.
