Balloon dilation of the Eustachian tube(s) is a surgical procedure performed endoscopically through the nasal passage. This technique utilizes a balloon catheter that is inserted into the Eustachian tube, which connects the middle ear to the nasopharynx. The primary purpose of this procedure is to improve the patency of the Eustachian tube and alleviate chronic ear congestion that may arise from conditions such as middle ear infections or mastoid infections. The Eustachian tube plays a crucial role in equalizing pressure and ventilating the ear, as it opens during actions like swallowing or yawning. During the procedure, a saline-filled balloon catheter is carefully introduced into the Eustachian tube using an endoscope, which is a specialized instrument designed for this purpose. Once the balloon is correctly positioned, it is inflated to maintain pressure for a few minutes, effectively stretching and opening the tube. After sufficient dilation, the balloon is deflated and removed, followed by the withdrawal of the endoscope and catheter. This procedure is typically conducted under general anesthesia to ensure patient comfort. For billing purposes, CPT® Code 69705 is used to report the dilation of one Eustachian tube, while CPT® Code 69706 is designated for the dilation of both tubes.

The procedure of nasopharyngoscopy with dilation of the Eustachian tube is indicated for patients experiencing chronic ear congestion, which may be due to various underlying conditions. The following are specific indications for performing this procedure:
The procedure involves several key steps to ensure effective dilation of the Eustachian tube:
After the procedure, patients may experience some temporary discomfort or pressure in the ear, which is generally expected. Post-procedure care may include monitoring for any signs of complications, such as infection or excessive bleeding. Patients are typically advised to avoid activities that may increase pressure in the ears, such as flying or diving, for a short period following the procedure. Follow-up appointments may be scheduled to assess the effectiveness of the dilation and to monitor the patient's recovery.

| 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. |
| LT | Left side (used to identify procedures performed on the left side of the body) |
| 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). |
| 52 | Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient 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). |
| 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. |
| 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. |
| 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.) |
| 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.) |
| 80 | Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s). |
