Poisoning by antidiarrheal drugs, accidental, subs

This code signifies an accidental overdose or adverse reaction to antidiarrheal medications, such as loperamide or bismuth subsalicylate, during a follow-up visit. The patient is experiencing ongoing effects or complications from the initial unintentional poisoning event.

Apply this code when documenting subsequent care for a patient who inadvertently ingested an excessive amount of antidiarrheal medication. This includes follow-up appointments for monitoring symptoms, managing ongoing side effects, or addressing complications that arose from the initial poisoning.

• Ensure the encounter is for follow-up care related to the initial poisoning, not the initial presentation.
• Verify the poisoning was accidental (unintentional) and not self-harm or assault.
• Confirm the substance involved is an antidiarrheal drug.
