What 26535 covers
This operation reshapes or removes damaged surfaces at a finger interphalangeal joint to improve pain and function without placing a prosthetic implant. Hand surgeons typically perform it for a painful, stiff or deformed joint affected by arthritis or prior injury. The operative report should identify the specific finger joint and describe the joint work performed; this code is distinct from arthroplasty of a knuckle joint at the metacarpophalangeal level and from implant arthroplasty.
Report the service for each treated interphalangeal joint, supported by documentation of the joint and the nonimplant procedure. 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 50% multiple-procedure reduction. Modifier 50 is inappropriate for this code. Medicare does not pay an assistant at surgery, and co-surgeon and team-surgery billing are not permitted.
