Perf due to fb acc left in body fol inject or immuniz, init

This code signifies a perforation of a body organ or tissue that occurred as a direct result of a foreign object being unintentionally retained within the body after an injection or immunization procedure. The perforation is a complication stemming from the retained foreign body, which was inadvertently left behind during the initial medical intervention.

Apply this code when documentation clearly indicates a patient has suffered a perforation caused by a foreign object (e.g., a needle fragment, catheter tip) that was accidentally left in the body following an injection or immunization. This is for the initial phase of treatment for this specific complication.

• Always sequence this code as a secondary diagnosis, following the code for the specific type of perforation.
• Ensure the medical record explicitly links the perforation to a retained foreign body from an injection or immunization.
• Verify the encounter is for the initial treatment of the perforation; subsequent encounters would use a different seventh character.
