What 64716 covers
This operation involves surgically freeing a cranial nerve from restrictive scar or surrounding tissue, and/or mobilizing it into a different position to address tethering or compression. Neurosurgeons and head-and-neck surgeons may perform this work in an operating room when a cranial nerve is directly exposed and treated; incidental nerve exposure during a nearby operation is not enough to support the service.
The operative report should identify the cranial nerve and describe the release or repositioning performed, rather than only exploration or intentional nerve transection. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is not appropriate for this cranial-nerve service. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

How to choose
- 64727Internal neurolysis

- 64742Facial nerve surgery
- Use 64742 for intentional facial nerve transection. Use 64716 when the cranial nerve is freed or repositioned rather than cut.
- 64708Nerve neuroplasty
- 64708 addresses revision of an arm or leg nerve. Select 64716 when the nerve treated is cranial.
- 64732Brow nerve surgery
- 64732 represents transection of the supraorbital nerve; 64716 describes cranial nerve release or repositioning.
64716 billing questions
How is this different from transecting a cranial nerve?
This code describes freeing or repositioning a cranial nerve. A procedure that intentionally cuts a nerve is a different service, such as the facial nerve procedure represented by 64742.
Can internal neurolysis be reported with this service?
billing code 64727 is an add-on for qualifying internal neurolysis performed with a neuroplasty. The operative documentation should support that distinct work.
What should the operative report document?
Identify the cranial nerve and explain the actual release or repositioning performed. A note describing only exposure, inspection, or transection does not establish this service.
Should modifier 50 be used for work on both sides?
No. Modifier 50 is not appropriate for this cranial-nerve service.
How does the 90-day global affect postoperative claims?
The day-before preoperative visit and 90 days of related postoperative care are included in the global period.
How are multiple procedures in the same session paid?
The highest-valued procedure is paid in full; other procedures in the session are subject to the standard 50% multiple-procedure reduction.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
