Poisoning by other bacterial vaccines, assault, subs encntr

This code indicates an adverse effect resulting from the administration of a bacterial vaccine, where the intent of the administration was malicious (assault). It specifically applies when the patient is receiving follow-up care for the poisoning after the initial treatment.

Use this code for patients presenting for ongoing management of symptoms or complications arising from a bacterial vaccine administered with the intent to harm. This would include follow-up visits for organ damage, allergic reactions, or other systemic effects caused by the vaccine.

• Ensure documentation clearly states the poisoning was due to a bacterial vaccine and the intent was assault.
• Verify this is a subsequent encounter; for initial treatment, use the 'A' seventh character.
• Always code the specific manifestation of the poisoning first, followed by this external cause code.
