Nasal/sinus endoscopy with dilation, specifically CPT® Code 31295, refers to a surgical procedure that utilizes an endoscope to perform dilation of the maxillary sinus ostium, which is the opening of the maxillary sinus. This procedure is primarily indicated for patients suffering from chronic sinusitis characterized by obstruction of the sinus ostium. The dilation process involves the use of a balloon that is inserted into the sinus ostium to expand it, thereby alleviating the blockage and restoring normal drainage of the sinus. The procedure is typically performed under local anesthesia, which may include a topical nasal decongestant and a vasoconstrictor to minimize bleeding and discomfort. The endoscope is carefully introduced through the nasal passage and navigated to the affected sinus area. In some cases, particularly for accessing the maxillary sinus, the procedure may involve puncturing the canine fossa, a specific anatomical location in the upper jaw, to facilitate access. The dilation is achieved by inflating and deflating the balloon multiple times to ensure adequate expansion of the ostium, which is then inspected through the endoscope to confirm successful dilation. This procedure is essential for improving sinus drainage and alleviating symptoms associated with chronic sinusitis.

The procedure described by CPT® Code 31295 is indicated for the treatment of chronic sinusitis, particularly when there is an obstruction of the maxillary sinus ostium. This condition often leads to symptoms such as nasal congestion, facial pain or pressure, and difficulty breathing through the nose. The endoscopic dilation aims to relieve these symptoms by restoring normal drainage of the affected sinus.
The procedure involves several key steps to ensure effective dilation of the maxillary sinus ostium. Initially, a topical nasal decongestant and local anesthetic with a vasoconstrictor are applied to the nasal passages to minimize discomfort and reduce bleeding during the procedure.
After the procedure, patients may experience some discomfort, which is typically managed with prescribed pain relief medications. It is important for patients to follow any post-operative care instructions provided by their healthcare provider, which may include recommendations for nasal saline irrigation to promote healing and reduce crusting. Patients should also be monitored for any signs of complications, such as excessive bleeding or infection. Follow-up appointments may be scheduled to assess recovery and ensure that the sinus ostium remains patent, allowing for normal sinus drainage.
