Poisoning by other bacterial vaccines, undetermined, sequela

This code signifies a long-term or residual effect resulting from an undetermined poisoning by a bacterial vaccine other than BCG, typhoid, or tetanus. It indicates that the acute phase of the poisoning has passed, but the patient continues to experience health problems directly attributable to the vaccine exposure. The specific bacterial vaccine involved is not identified.

Assign this code when a patient presents with a chronic condition or permanent injury that is documented as a sequela of an unconfirmed or unspecified bacterial vaccine poisoning. This would apply after the initial poisoning event has resolved, and the current encounter addresses the lasting consequences. Use when the medical record clearly links the current condition to a past, undetermined bacterial vaccine poisoning.

• Always sequence this code after the code(s) for the specific sequela being treated (e.g., neurological damage, organ dysfunction).
• Ensure documentation explicitly states "sequela" or "late effect" and links the current condition to a past poisoning by an unspecified bacterial vaccine.
• Do not use for acute poisoning events; refer to the appropriate acute poisoning codes.
