Peripheral nerve surgery
About 64722: Decompression of an unspecified peripheral nerve
Reports surgical release of a compressed peripheral nerve when the operative nerve does not fit a more specifically named decompression code.
A surgeon exposes a compressed peripheral nerve and releases constricting tissue to relieve pressure on the nerve. The code is for an unspecified nerve, so the operative report should identify the nerve and anatomic site even though the code does not name either. Peripheral nerve decompression is typically performed in an operating room or ambulatory surgery setting for a documented entrapment or other compression problem.
Select this code when a more specific nerve or site code does not describe the operation. Document the nerve, location, compression findings, and release performed. Medicare assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others are subject to the standard 50% multiple-procedure reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment may be allowed; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

64726 is specific to a plantar digital nerve. 64722 is the unspecified-nerve option when that named nerve and site are not involved.
No office rate
64718 identifies ulnar nerve surgery at the elbow. Choose it for that named nerve and site rather than reporting an unspecified-nerve decompression.

64722 billing questions
When should this code be chosen instead of a named-nerve decompression code?
Use it when the operation decompresses a nerve that is not represented by a more specific nerve or site code. The operative report should still name the nerve and its location.
Can it be reported for carpal tunnel release?
For decompression of the median nerve at the carpal tunnel, compare the specific carpal tunnel code 64721 rather than defaulting to an unspecified-nerve code.
How does the multiple-procedure rule affect payment?
When this and other procedures are performed in the same session, Medicare pays the highest-valued procedure in full and applies the standard 50% reduction to the others.
Should modifier 50 be appended for bilateral decompression?
No. CMS identifies bilateral adjustment as inappropriate for this code.
What should the operative note support?
Document the nerve and anatomic site, the compression addressed, and the release performed. These details support use of this unspecified code rather than a more specific nerve code.
How are assistant and co-surgeon services handled?
Assistant-at-surgery payment may be allowed. Co-surgeon payment requires supporting documentation, while team surgery is 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 indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
