Poisoning by antidiarrheal drugs, assault, sequela

This code signifies a long-term health consequence resulting from an intentional act of poisoning with antidiarrheal medications. It indicates that the patient is experiencing residual effects or complications from a past assault involving these drugs, rather than an acute event. The "sequela" aspect means the initial acute phase of the poisoning has passed, and the current encounter addresses ongoing issues.

Apply this code when a patient presents for treatment of chronic conditions, organ damage, or other lasting health problems directly attributable to a prior assault where antidiarrheal drugs were used as the poison. This is appropriate for follow-up visits addressing the long-term impact, such as managing persistent gastrointestinal issues, cardiac arrhythmias, or neurological deficits caused by the past poisoning.

• Always sequence this code after the code(s) for the specific sequelae being treated (e.g., chronic constipation, cardiac dysrhythmia).
• Ensure documentation clearly links the current condition to a past assault involving antidiarrheal drugs.
• Verify the encounter is for the sequela and not an acute poisoning event, which would use different codes.
