T45.94XA
ICD-10-CMPoisoning by unspecified primarily systemic and hematological agent, undetermined, initial encounter
This code signifies an adverse health event resulting from exposure to an unknown substance that primarily affects the body's systems or blood, where the intent of the poisoning (e.g., accidental, intentional) cannot be determined. The patient is presenting for the initial treatment of this poisoning.
Apply this code when a patient presents with symptoms of poisoning, and the specific toxic agent is not yet identified or documented. It is also appropriate when the circumstances surrounding the exposure (e.g., accidental ingestion, self-harm attempt) are unclear or not specified in the medical record.
