Nasal/sinus endoscopy, surgical, with dilation (CPT® Code 31298) refers to a minimally invasive procedure aimed at treating chronic sinusitis characterized by obstruction of the sinus ostium, which is the opening of the sinus. This procedure involves the use of an endoscope, a specialized instrument that allows the physician to visualize the interior of the nasal passages and sinuses. The primary goal of the endoscopic dilation is to restore normal drainage of the affected sinuses by enlarging the ostium. This is achieved through the inflation of a small balloon that compresses the surrounding mucosa and displaces bony structures, thereby widening the opening and alleviating the blockage. Prior to the procedure, a topical nasal decongestant and a local anesthetic with a vasoconstrictor may be applied to minimize discomfort and reduce bleeding. The endoscope is carefully introduced through the nasal cavity and navigated to the targeted paranasal sinus. In cases where dilation of the maxillary sinus is required, a trocar may be used to puncture the canine fossa, which is a specific anatomical area located in the maxilla. A guidewire catheter equipped with a balloon is then advanced into the blocked sinus ostium, where the balloon is inflated and deflated multiple times to ensure adequate dilation. The procedure concludes with the inspection of the ostium using the endoscope, followed by the removal of the endoscope itself. This code specifically applies to the dilation of both the frontal and sphenoid sinus ostia, distinguishing it from other related codes that pertain to the dilation of individual sinus ostia.

The procedure described by CPT® Code 31298 is indicated for patients suffering from chronic sinusitis that is characterized by obstruction of the sinus ostium. This condition may present with various symptoms, including but not limited to:
The surgical procedure for nasal/sinus endoscopy with dilation involves several key steps, which are detailed as follows:
Following the endoscopic dilation procedure, patients may experience some discomfort, which is typically managed with prescribed pain relief medications. It is important for patients to follow 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 the success of the procedure and to ensure that normal sinus drainage has been restored.

| 50 | Bilateral procedure: unless otherwise identified in the listings, bilateral procedures that are performed at the same session, should be identified by adding modifier 50 to the appropriate 5 digit code. note: this modifier should not be appended to designated "add-on" codes (see appendix d). | RT | Right side (used to identify procedures performed on the right side of the body) | AS | Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery | 80 | Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s). | LT | Left side (used to identify procedures performed on the left side of the body) | 81 | Minimum assistant surgeon: minimum surgical assistant services are identified by adding modifier 81 to the usual procedure number. | 51 | Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d). | 79 | Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.) | 22 | Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service. | 53 | Discontinued procedure: under certain circumstances, the physician or other qualified health care professional may elect to terminate a surgical or diagnostic procedure. due to extenuating circumstances or those that threaten the well being of the patient, it may be necessary to indicate that a surgical or diagnostic procedure was started but discontinued. this circumstance may be reported by adding modifier 53 to the code reported by the individual for the discontinued procedure. note: this modifier is not used to report the elective cancellation of a procedure prior to the patient's anesthesia induction and/or surgical preparation in the operating suite. for outpatient hospital/ambulatory surgery center (asc) reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use). | 58 | Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78. | 59 | Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25. | 74 | Discontinued out-patient hospital/ambulatory surgery center (asc) procedure after administration of anesthesia: due to extenuating circumstances or those that threaten the well being of the patient, the physician may terminate a surgical or diagnostic procedure after the administration of anesthesia (local, regional block(s), general) or after the procedure was started (incision made, intubation started, scope inserted, etc). under these circumstances, the procedure started but terminated can be reported by its usual procedure number and the addition of modifier 74. note: the elective cancellation of a service prior to the administration of anesthesia and/or surgical preparation of the patient should not be reported. for physician reporting of a discontinued procedure, see modifier 53. | 76 | Repeat procedure or service by same physician or other qualified health care professional: it may be necessary to indicate that a procedure or service was repeated by the same physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 76 to the repeated procedure or service. note: this modifier should not be appended to an e/m service. | 78 | Unplanned return to the operating/procedure room by the same physician or other qualified health care professional following initial procedure for a related procedure during the postoperative period: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, see modifier 76.) | CG | Policy criteria applied | GA | Waiver of liability statement issued as required by payer policy, individual case | GC | This service has been performed in part by a resident under the direction of a teaching physician | GW | Service not related to the hospice patient's terminal condition | SG | Ambulatory surgical center (asc) facility service | XE | Separate encounter, a service that is distinct because it occurred during a separate encounter | XS | Separate structure, a service that is distinct because it was performed on a separate organ/structure | XU | Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service |
