Typical Clinical Scenarios

An elderly patient with a history of chronic maxillary sinus drainage presents with acute retention of a previously placed sinus drainage catheter that is nonfunctional and causing recurrent infection; the patient is admitted for inpatient removal because bedside attempts failed and there is concern for surrounding cellulitis requiring hospital-level care. The procedure is performed to remove the obstructed drainage device from the sinus to control infection and allow definitive management. Typical codes: 09PY00Z, 09PYX0Z
A middle-aged patient undergoing planned inpatient revision of a previously placed sinus stent that was implanted after endoscopic sinus surgery develops granulation tissue and persistent obstruction; during the scheduled admission the clinician removes the malfunctioning stent endoscopically to prepare for revision surgery. The operation is elective and performed via a percutaneous endoscopic or natural opening endoscopic approach depending on access. Typical codes: 09PY4YZ, 09PY8YZ
A young adult presents to the emergency department with facial trauma after a motor vehicle collision and has a displaced foreign device fragment lodged within a sinus with associated hemorrhage and airway concerns; the patient is taken to the OR urgently for extraction of the device fragment to control bleeding and prevent intracranial extension. Because the removal may require an open approach given fragment position, an open removal code is used. Typical codes: 09PY0YZ, 09PY00Z
