Poisn by pertuss vaccine, inc combin w pertuss, asslt, sqla

This code signifies a long-term health problem or complication arising from a past poisoning event involving a pertussis vaccine or a vaccine containing a pertussis component. The poisoning was intentionally inflicted by another person. The sequela could be any lasting adverse effect directly attributable to the toxic exposure.

Apply this code when documenting a chronic condition or permanent injury that is a direct result of a previous poisoning by a pertussis-containing vaccine, where the poisoning was an act of assault. This would be used in follow-up encounters for conditions like persistent neurological damage, chronic allergic reactions, or other lasting systemic effects.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to the past poisoning and specifies the assaultive nature of the event.
• A seventh character of 'S' indicates sequela, meaning the acute phase of the poisoning has passed.
