Oth comp of fb acc left in body fol inject or immuniz, sqla

This code describes a long-term or late-developing adverse effect resulting from a foreign object, such as a needle fragment or part of a device, inadvertently remaining within the body after an injection or immunization procedure. These complications are not immediate and manifest after the initial healing period.

This code is appropriate for documenting chronic pain, infection, nerve damage, or other persistent issues directly attributable to a retained foreign body following an injection or immunization. It should be used when the patient presents for treatment of these lasting complications.

• Always assign this code as a secondary diagnosis, with the primary code reflecting the specific sequela (e.g., chronic pain, infection).
• Ensure documentation clearly links the current complication to a retained foreign body from a prior injection or immunization.
• This "S" seventh character indicates a sequela, meaning the complication is a late effect of the initial event.
