What 64718 covers
This operation addresses the ulnar nerve where it passes the elbow, often for cubital tunnel syndrome or nerve compression, tethering, or irritation. The surgeon frees the nerve from constricting tissue and may move it to a new position when the clinical findings call for transposition. Orthopedic, hand, plastic, or neurosurgeons commonly perform the procedure in an operating room, usually in a facility setting.
Report the code when the operative work involves the ulnar nerve at the elbow; a transposition is not required in every case. The operative report should identify the nerve and elbow site, the condition treated, and the release or repositioning performed. This major surgery has a 90-day global period that includes the day-before preoperative visit and related postoperative care during that period. When multiple procedures occur in one session, the highest-valued procedure is paid in full and the others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment requires documentation of medical necessity; co-surgeons and team surgery are not permitted.

64718 billing questions
Does the nerve have to be transposed?
No. The code covers freeing the ulnar nerve at the elbow, with transposition performed when indicated. The operative report should make clear which work was done.
How is this different from 64719?
This code is for ulnar nerve surgery at the elbow. Code 64719 concerns the ulnar nerve at the wrist.
Can the surgeon report 64727 with this procedure?
Code 64727 may be relevant when internal neurolysis requiring an operating microscope is separately performed and documented in addition to the primary nerve procedure.
How is bilateral surgery paid?
CMS pays bilateral reporting with modifier 50 at 150%. The operative documentation should support treatment of both elbows.
What happens when other procedures are performed in the same session?
Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and the other procedures are paid at 50%.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment requires documentation of medical necessity. Co-surgeons and team surgery are not permitted for this code.
