Otolaryngology surgery
About 69910: Labyrinthectomy with mastoidectomy
Reports surgical removal of the inner-ear labyrinth through a mastoid approach, typically to control severe, persistent vertigo when hearing in that ear is not serviceable.
An otologist, neurotologist, or other otolaryngologic surgeon removes the inner-ear labyrinth through a mastoid approach. The operation is used for disabling vertigo that persists despite treatment, such as in selected patients with unilateral Ménière disease and nonserviceable hearing in the affected ear. It ablates vestibular function on that side and sacrifices any remaining hearing there. The procedure is generally performed in an operating room.
Report 69910 when the documented operation includes labyrinthectomy with mastoidectomy; the mastoid approach and removal of the labyrinth are represented together by this code. The operative report should identify the treated side, the mastoid approach, the labyrinth removal, and the clinical reason for surgery. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 for bilateral surgery is paid at 150%. Assistant-at-surgery payment requires documentation of medical necessity; co-surgeons and team surgery are not permitted.

69910 billing questions
How does 69910 differ from 69905?
69910 describes labyrinthectomy with a mastoid approach. 69905 is the transcanal labyrinthectomy code, so select based on the documented surgical approach.
Can the mastoidectomy be reported separately?
The mastoid approach and mastoidectomy are part of the service represented by 69910. Do not separately report the included mastoidectomy as though it were an independent service.
When is 69910 preferable to a vestibular nerve section code?
Use 69910 when the surgeon removes the labyrinth through the mastoid approach. A vestibular nerve section code describes cutting the vestibular nerve rather than removing the labyrinth.
How is bilateral surgery handled?
CMS pays bilateral surgery reported with modifier 50 at 150%. The operative documentation should support treatment of both sides.
What documentation supports assistant-at-surgery payment?
Document the assistant's role and the medical necessity for assistance with this operation. CMS permits assistant-at-surgery payment only when medical necessity is documented.
