What 64408 covers

This service places anesthetic at the vagus nerve to interrupt or assess nerve-mediated symptoms. A recognized clinical use is a vagal sensory block, including a superior laryngeal nerve block, for selected patients with neurogenic cough. Pain physicians, anesthesiologists, and otolaryngologists may perform the injection in an office or procedural setting; the record should identify the nerve target, side, indication, and technique.

Select 64408 when the documented target is the vagus nerve, rather than another named nerve or an unspecified peripheral nerve. The code has a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and the others at 50%. For bilateral treatment, modifier 50 is paid at 150%. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

64408 billing questions

When should 64408 be selected instead of 64450?

Use 64408 when the documented injection target is the vagus nerve. Code 64450 describes an injection of an other peripheral nerve or branch when a more specific code does not identify the target.

Can 64408 be reported for a neurogenic cough block?

It may describe a vagal sensory block, including a superior laryngeal nerve block, when the documentation identifies the vagal target and supports the service performed.

How is bilateral treatment reported?

When the vagus nerve is treated bilaterally, report modifier 50; CMS pays the bilateral procedure at 150%.

What same-day care is included?

The 0-day global period includes same-day preoperative and postoperative care. Services on a different date are not covered by that same-day global period.

How does CMS handle another procedure performed in the same session?

Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and other procedures are paid at 50%.

Can an assistant or co-surgeon be reported?

Assistant-at-surgery payment is available only with documentation of medical necessity. Co-surgeons and team surgery are not permitted.

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.
