Obst due to fb acc left in body fol inject or immuniz, subs

This code signifies a patient presenting for ongoing care of an obstruction caused by a foreign object, such as a needle fragment or a piece of a catheter, that was inadvertently retained in their body after an injection or immunization procedure. The obstruction is a direct consequence of this retained foreign material.

Apply this code when a patient returns for follow-up treatment, monitoring, or further intervention related to an obstruction caused by a foreign body left behind from a prior injection or immunization. This includes situations where the patient is experiencing symptoms attributable to the obstruction, or when surgical removal or other management of the retained object is being planned or performed during this encounter.

• Ensure documentation clearly links the obstruction to a foreign body from a prior injection/immunization.
• Confirm the encounter is for subsequent care, not the initial discovery or acute treatment.
• Always sequence this code after the primary diagnosis describing the specific type of obstruction, if applicable.
