Poisoning by oth bacterial vaccines, undetermined, subs

This code signifies a poisoning event resulting from an unspecified bacterial vaccine, where the intent of the poisoning cannot be determined. It is used when the patient is receiving ongoing care for the adverse effects of this poisoning.

This code is appropriate for follow-up visits or continuing treatment for a patient who experienced an adverse reaction to a bacterial vaccine, and the circumstances surrounding the reaction (e.g., accidental, intentional self-harm) are unknown. It should be applied when documentation indicates the patient is still being managed for the sequelae of the poisoning.

• Ensure documentation clearly states "undetermined" intent for the poisoning.
• Verify the encounter is for subsequent care related to the initial poisoning event.
• Always code the specific bacterial vaccine if known, using a more specific code if available.
