Infection following immunization, sequela

This code describes a long-term or residual effect resulting from an infection that occurred as a complication of an immunization. It signifies that the acute infection has resolved, but the patient continues to experience a lasting health problem directly attributable to that post-immunization infection.

Use this code when documenting a chronic condition, disability, or other persistent health issue that is a direct consequence of an infection that developed after a vaccination. This applies when the original infection is no longer active, but its impact on the patient's health remains.

• Always sequence this code after the code for the specific sequela (e.g., chronic osteomyelitis, nerve damage).
• Ensure documentation clearly links the current condition to a past infection that was a complication of an immunization.
• Do not use for acute infections following immunization; refer to codes in the T88.0XXA or T88.0XXD categories for active or resolving infections.
