Poisoning by aspirin, undetermined, initial encounter

This code signifies an adverse health event resulting from aspirin ingestion where the intent (e.g., accidental, intentional self-harm, assault) cannot be determined. The patient is presenting for the initial treatment of the poisoning symptoms.

Apply this code when a patient presents with symptoms of aspirin toxicity, and documentation clearly indicates that the circumstances surrounding the ingestion are unknown or unspecified. This is appropriate for the first visit or encounter related to this specific poisoning episode.

• Always sequence this code first when it represents the primary reason for the encounter.
• Do not use this code if the intent of the aspirin poisoning is documented as accidental, intentional self-harm, or assault.
• Ensure documentation supports "undetermined" intent; otherwise, query the provider for clarification.
