The procedure described by CPT® Code 69950 refers to a vestibular nerve section performed via a transcranial approach, which is also known as the middle cranial fossa approach. This surgical intervention is specifically indicated for patients experiencing severe recurrent episodes of vertigo, a condition characterized by a sensation of spinning or dizziness. The vestibular nerve, which is responsible for transmitting balance information from the inner ear to the brain, is targeted in this procedure to alleviate the debilitating symptoms associated with vestibular disorders. The surgical technique involves making a long curvilinear incision over the temporal bone on the side affected by vertigo. Following this incision, a lateral craniectomy is executed to expose the temporal lobe, which is then retracted medially to provide access to the superior surface of the temporal bone. The internal auditory canal is subsequently identified and opened, allowing the surgeon to locate and section both the superior and inferior vestibular nerves. After the nerve sectioning is completed, the surgical site is irrigated, the bone flap is replaced and secured, and the soft tissues are meticulously closed to promote healing. This detailed approach ensures that the procedure is performed with precision, aiming to significantly reduce or eliminate the patient's vertiginous symptoms.

The vestibular nerve section via a transcranial approach is indicated for patients who suffer from severe recurrent attacks of vertigo. This condition can significantly impact the quality of life, leading to debilitating symptoms that may not respond to conservative treatments. The procedure aims to provide relief from these debilitating episodes by targeting the vestibular nerve, which plays a crucial role in balance and spatial orientation.
The vestibular nerve section procedure involves several critical steps to ensure successful outcomes.
Post-procedure care following a vestibular nerve section is essential for recovery. Patients are typically monitored for any immediate complications related to the surgery. Pain management is provided as needed, and patients may be advised to limit physical activity during the initial recovery phase. Follow-up appointments are crucial to assess the surgical site and monitor for any signs of infection or complications. Additionally, patients may undergo vestibular rehabilitation therapy to aid in recovery and help them adjust to changes in balance and spatial orientation following the procedure.

| 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). | 62 | Two surgeons: when 2 surgeons work together as primary surgeons performing distinct part(s) of a procedure, each surgeon should report his/her distinct operative work by adding modifier 62 to the procedure code and any associated add-on code(s) for that procedure as long as both surgeons continue to work together as primary surgeons. each surgeon should report the co-surgery once using the same procedure code. if additional procedure(s) (including add-on procedure(s) are performed during the same surgical session, separate code(s) may also be reported with modifier 62 added. note: if a co-surgeon acts as an assistant in the performance of additional procedure(s), other than those reported with the modifier 62, during the same surgical session, those services may be reported using separate procedure code(s) with modifier 80 or modifier 82 added, as appropriate. | LT | Left side (used to identify procedures performed on the left side of the body) | RT | Right side (used to identify procedures performed on the right side of the body) |
