Medical Coding Exam Prep

Answer: D - The difference between anterior nasal packing versus posterior nasal packing procedure codes is that anterior packing applies pressure and gauze to the front of the nose, and posterior packing inserts a balloon into the back of the nasal cavity. Posterior packing includes packing the nose with gauze and applying pressure to the posterior aspect of the nasal cavity. This can include inserting a balloon to the back of the throat, which is inflated to block blood from draining into the back of the throat.
