Underdosing of macrolides, sequela

This code signifies a long-term or residual effect resulting from the patient not receiving enough macrolide antibiotics. This underdosing could have led to persistent infection, recurrence, or other complications that manifest after the initial underdosing event. The "S" indicates that this is a sequela, meaning the adverse effect is a late effect of the underdosing.

Use this code when documenting a condition or symptom that is a direct consequence of a past, insufficient dose of a macrolide antibiotic. This would apply, for example, if a patient presents with a chronic or recurrent infection that is definitively linked to a previous course of macrolide treatment that was inadequate. It is appropriate when the acute phase of the underdosing is over, but its lasting impact is still present.

• Always sequence this sequela code after the code for the specific condition or symptom caused by the underdosing.
• Ensure documentation clearly links the current condition to a previous, insufficient macrolide dosage.
• Do not use for acute underdosing; this code is specifically for the long-term effects.
