Obst due to fb acc left in body fol oth procedure, init

This code signifies a patient presenting with an obstruction caused by a foreign object that was unintentionally retained within the body after a surgical or other invasive medical procedure. The obstruction is a direct consequence of the retained foreign body, leading to symptoms such as pain, swelling, or organ dysfunction.

Apply this code when documentation clearly indicates an obstruction resulting from a surgical sponge, instrument fragment, or other material inadvertently left inside the patient during a prior procedure. This is for the initial encounter where the retained foreign body and subsequent obstruction are first identified and addressed.

• Ensure the documentation explicitly states "obstruction" as a direct result of the retained foreign body.
• Confirm the foreign body was "accidentally left" during a previous procedure, not intentionally placed (e.g., an implanted device).
• Use this specific code for the initial encounter; subsequent encounters for the same issue would require a different seventh character.
