Poisoning by aspirin, undetermined, subsequent encounter

This code signifies an aspirin poisoning where the intent (e.g., accidental, intentional self-harm) could not be determined by the provider. It is used for encounters following the initial treatment of the poisoning, such as follow-up visits or for managing lingering effects. The poisoning specifically refers to an adverse effect from aspirin, not other salicylates.

Use this code for follow-up care of a patient who previously presented with aspirin poisoning of undetermined intent. This includes visits for monitoring organ function, managing complications like gastrointestinal bleeding, or addressing persistent symptoms related to the initial poisoning. It is appropriate for any encounter after the acute phase of treatment has concluded.

• Ensure the documentation clearly states "undetermined" intent for the aspirin poisoning.
• Verify this is a subsequent encounter; for the initial encounter, a different 7th character would be used.
• Code any associated signs, symptoms, or complications of the poisoning separately, if applicable.
