About 26135: Finger interphalangeal joint revision
Reports surgical revision of a finger interphalangeal joint to address a joint problem requiring operative correction, counted for each treated joint.
This service involves surgically revising a finger joint between phalanges, such as a proximal or distal interphalangeal joint. A hand surgeon or other qualified surgeon may perform it in a facility operating room for a painful or function-limiting joint problem that requires operative correction. The record should identify the finger and joint and describe the condition and revision performed; the code represents the joint procedure, not simply evaluation of finger pain or a joint-lining biopsy.
Report the service for each interphalangeal joint revised, supported by the operative report and the documented anatomy and surgical work. CMS 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 other procedures are subject to the standard multiple-procedure reduction. Modifier 50 is inappropriate for this code. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

26135 billing questions
How is this different from a finger-joint synovectomy?
This code is for revision of the interphalangeal joint itself. A synovectomy removes diseased joint lining; it does not by itself represent joint revision.
How many units should be reported when more than one joint is revised?
The descriptor is for each joint. The operative report should identify each treated interphalangeal joint and the work performed.
Can modifier 50 be used when both hands are treated?
No. CMS identifies bilateral adjustment as inappropriate for this code. Report the documented joint services using applicable claim-line conventions.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
When is an assistant-at-surgery payable?
CMS payment for an assistant requires documentation of medical necessity. Co-surgeons and team surgery are not permitted.
