Underdosing of antidiarrheal drugs, sequela

This code signifies a patient presenting with a long-term or residual condition that is a direct consequence of insufficient or inadequate administration of antidiarrheal medication. This implies that the original underdosing event has resolved, but its lasting effects are still present and require ongoing management.

Apply this code when documenting a chronic or persistent symptom, disease, or complication that arose because a patient did not receive enough antidiarrheal medication at an earlier time. Examples include chronic dehydration, electrolyte imbalance, or malabsorption syndromes directly attributable to prolonged, uncontrolled diarrhea due to underdosing.

• Always sequence this code after the code for the specific sequela (e.g., chronic dehydration).
• Ensure documentation clearly links the current condition to a past underdosing event of antidiarrheal drugs.
• Do not use this code for acute underdosing events; it is specifically for the lasting effects.
