Toxic effect of ingested berries, accidental, sequela

This code signifies the long-term or residual health problems resulting from an accidental ingestion of toxic berries. It indicates that the acute phase of poisoning has passed, but the patient continues to experience lasting effects attributable to the initial exposure. These sequelae can range from chronic gastrointestinal issues to neurological deficits or organ damage.

Apply this code when documenting a patient's current medical condition that is a direct consequence of an unintentional ingestion of poisonous berries, and the initial poisoning event occurred in the past. This would be used for follow-up visits or ongoing treatment related to the lasting impact of the toxicity. For example, a patient presenting with chronic liver damage years after accidentally consuming toxic berries would be coded with this.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic liver failure).
• Ensure documentation clearly links the current condition to the past toxic berry ingestion.
• Verify that the "S" seventh character is appropriate, indicating a sequela, and not an initial encounter or subsequent encounter for the acute poisoning.
