Poisoning by rifampicins, undetermined, initial encounter

This code signifies a case of poisoning resulting from rifampicin, an antibiotic commonly used to treat tuberculosis and other bacterial infections. The circumstances surrounding the poisoning, such as whether it was accidental or intentional, are not yet determined. The "initial encounter" indicates that the patient is receiving active treatment for the poisoning.

Use this code when a patient presents with signs and symptoms of rifampicin toxicity, and the provider has not yet established the intent behind the exposure. This applies to the first time the patient is seen for this specific poisoning event, such as in an emergency department or during an initial hospitalization.

• Ensure documentation clearly states rifampicin as the causative agent and that the intent is unknown.
• Pair this code with external cause codes (V00-Y99) to provide more detail about the circumstances of the poisoning, if known.
• Do not use this code for adverse effects of properly administered rifampicin; instead, use codes from the T36.6X5- series.
