Poisoning by fluoroquinolone antibiotics, undetermined, init

This code signifies an adverse event resulting from the ingestion or exposure to fluoroquinolone antibiotics, where the intent (accidental, intentional self-harm, assault) cannot be determined. The patient is experiencing the initial phase of symptoms or treatment for this poisoning.

Apply this code when a patient presents with signs and symptoms of fluoroquinolone toxicity, and the provider's documentation explicitly states that the intent of the poisoning is undetermined. This is appropriate for the first encounter related to the poisoning event, such as an emergency department visit or initial hospitalization.

• Ensure provider documentation clearly states "undetermined" intent for the poisoning.
• Verify this is the initial encounter for the poisoning; subsequent encounters will require a different seventh character.
• Do not use this code if the intent (accidental, intentional) is known or suspected.
