Hand surgery
About 26140: Finger interphalangeal joint synovectomy
Reports surgical removal of diseased synovial tissue from a finger interphalangeal joint, including the associated extensor mechanism, one joint at a time.
A hand surgeon removes abnormal or chronically inflamed synovial tissue from a finger interphalangeal joint and addresses the associated extensor mechanism. The procedure is used when synovial disease at that joint warrants operative treatment, such as persistent inflammatory synovitis. It is distinct from removing a tendon-sheath lesion or taking synovium only for diagnostic biopsy.
Report one unit for each interphalangeal joint treated, with the operative note identifying the joint and documenting the synovial disease and work performed. This is major surgery with a 90-day global period; the day-before preoperative visit and 90 days of related postoperative care are included. 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 50% multiple-procedure reduction. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this code, and co-surgeons and team surgery are not permitted.

26140 billing questions
How does this differ from 26135?
26140 is for synovectomy at a finger interphalangeal joint. 26135 is for synovectomy at a metacarpophalangeal joint.
Is this the code for a synovial biopsy?
No. This code reports therapeutic removal of diseased synovial tissue. A joint arthrotomy performed to obtain a synovial biopsy is a different service, such as 26110 or 26105 depending on the joint.
How many units should be reported?
Report one unit for each interphalangeal joint treated. The operative note should identify each joint and the synovectomy performed there.
Can modifier 50 be used for both hands?
No. The CMS bilateral adjustment does not apply, and modifier 50 is inappropriate for this code.
Is related postoperative care separately billable?
Related postoperative care during the 90-day global period is included. The global period also includes the day-before preoperative visit.
Can an assistant surgeon or co-surgeon be reported?
Medicare does not pay an assistant at surgery for this code. Co-surgeons and team surgery are not permitted.
