What 64624 covers
This procedure destroys genicular nerve branches that carry pain signals from the knee, most commonly through radiofrequency lesioning. Interventional pain physicians and other clinicians who perform image-guided pain procedures use it for selected patients with persistent knee pain, including pain associated with osteoarthritis. The code covers treatment of three or more genicular nerve branches and includes imaging guidance when performed.
Report the code once for the treated knee when three or more branches are destroyed; treatment of only one or two genicular branches is generally reported with 64640 instead. The procedure note should identify the treated side and branches, the neurolytic technique, and any imaging guidance. A 10-day global period includes related postoperative visits during that period. When multiple procedures are performed in the same 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 documented medical necessity; co-surgeons and team surgery are not permitted.
