Underdosing of other bacterial vaccines, sequela

This code indicates a long-term consequence or complication arising from the patient not receiving an adequate dose of a bacterial vaccine. This could be due to an incomplete vaccination series, a dose that was too low to be effective, or a vaccine that was administered improperly, leading to a delayed or chronic health issue.

Use this code when documenting a condition that is a direct result of insufficient or absent administration of a bacterial vaccine. This applies when the patient presents with a disease or complication that the vaccine was intended to prevent, and the underdosing is identified as the causal factor for the sequela.

• Always code the specific sequela (the resulting condition) first, followed by this code to indicate the underdosing as the cause.
• Ensure documentation clearly links the current condition to the underdosing of a bacterial vaccine.
• This code is for other bacterial vaccines; avoid using it for specific bacterial vaccines that have their own underdosing codes.
