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.

How to choose

64640Nerve treatment
Choose 64624 for destruction of three or more genicular nerve branches. For one or two genicular branches, 64640 is generally used.
64625Radiofrequency ablation
64625 treats nerves associated with the sacroiliac joint; 64624 treats genicular nerve branches supplying the knee.
64633Facet ablation
64633 is for neurolytic denervation of cervical or thoracic facet joints. It does not describe knee genicular nerve treatment.
64635Facet nerve ablation
64635 is for neurolytic denervation of lumbar or sacral facet joints. Use 64624 for qualifying genicular nerve destruction at the knee.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
