What 64632 covers
This procedure chemically ablates a plantar common digital nerve, often to treat persistent burning or shooting forefoot pain associated with a Morton's neuroma. A podiatrist, foot and ankle specialist, or pain physician may perform it by directing a neurolytic agent to the affected nerve. It is distinct from an injection using local anesthetic or steroid for temporary symptom relief.
Select the code when documentation supports neurolytic destruction of the plantar common digital nerve, rather than another peripheral nerve or a non-neurolytic injection. Record the treated nerve, side, indication, and neurolytic treatment performed. CMS assigns a 10-day global period, so related postoperative visits during that period are included. For bilateral treatment, modifier 50 is paid at 150%. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and others at 50%. Assistant-at-surgery payment requires documentation of medical necessity; co-surgeons and team surgery are not permitted.
