About 26517: Metacarpophalangeal joint fusion
Reports surgical fusion of a metacarpophalangeal knuckle joint to stabilize a painful, deformed, or unstable joint in the hand.
A hand surgeon surgically fuses a metacarpophalangeal (MCP) joint, the knuckle where a finger meets the hand, to create a stable joint by eliminating motion there. The procedure may be considered for severe joint disease, deformity, or instability when preserving motion is not the goal. It is performed in an operating room, commonly in a hospital or ambulatory surgery center. The operative report should identify the finger and MCP joint treated and describe the fusion performed.
Report this code for the MCP fusion work documented in the operative note; distinguish it from procedures on the finger’s interphalangeal joints and from joint reconstruction or contracture release. The code has 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 others at 50%. For bilateral procedures reported with modifier 50, CMS pays 150%. An assistant at surgery may be paid; co-surgeons and team surgery are not permitted.

26517 billing questions
How is this code distinguished from a finger-joint fusion?
This code is for fusion at the MCP knuckle, where the finger meets the hand. A fusion at a finger interphalangeal joint is a different anatomic service.
What documentation supports reporting the code?
The operative report should identify the MCP joint and finger treated and describe the fusion performed. Include the indication and laterality when documented.
How is bilateral MCP fusion paid?
CMS lists bilateral reporting with modifier 50 at 150%. The operative documentation should establish that the procedure was performed on both sides.
What happens when another procedure is performed in the same session?
Under the standard multiple-procedure reduction, the highest-valued procedure is paid in full and the other procedure or procedures are paid at 50%.
Can an assistant surgeon be paid for this procedure?
CMS permits payment for an assistant at surgery. Co-surgeons and team surgery are not permitted for this code.
What postoperative care is included in the global period?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
