Poisoning by antidiarrheal drugs, undetermined, sequela

This code signifies a long-term health condition or complication resulting from an antidiarrheal drug poisoning where the intent (accidental, intentional self-harm, assault) could not be determined. The patient is no longer in the acute phase of the poisoning but is experiencing residual effects.

Use this code when documenting chronic kidney disease, neurological damage, or other persistent health issues directly attributable to a past antidiarrheal drug overdose of unknown intent. This code is appropriate for follow-up encounters after the initial poisoning event has resolved.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic kidney disease).
• Ensure documentation clearly links the current condition to the past antidiarrheal poisoning of undetermined intent.
• Do not use this code for acute poisoning events; instead, use the appropriate acute poisoning code with the 7th character for initial or subsequent encounter.
