Poisoning by aspirin, intentional self-harm, init encntr

This code signifies an adverse health event resulting from the deliberate ingestion of aspirin with the intent to cause self-harm. The patient is presenting for initial treatment of the acute poisoning and its immediate effects. This typically involves symptoms such as tinnitus, nausea, vomiting, hyperventilation, and metabolic acidosis.

Apply this code when a patient presents to an emergency department or inpatient setting following an intentional overdose of aspirin. This includes scenarios where the patient explicitly states self-harm intent or when clinical evidence strongly suggests it (e.g., suicide note, witness testimony). It is specifically for the initial encounter for treatment of the acute poisoning.

• Always sequence this code as the primary diagnosis when the poisoning is the reason for the encounter.
• Do not use this code for accidental aspirin poisoning; refer to codes in the T39.011- series for accidental cases.
• Remember the 7th character 'A' indicates an initial encounter for active treatment of the poisoning. Subsequent encounters for sequelae or long-term effects will require different 7th characters.
