What 64455 covers
A clinician injects anesthetic, steroid, or both around a plantar common digital nerve in the forefoot. The service is commonly performed in an office by a podiatrist, orthopedic clinician, or pain specialist for symptoms such as burning or radiating pain in the ball of the foot associated with suspected Morton's neuroma. The record should identify the treated nerve and side, the clinical indication, and the medication and injection performed.
Report 64455 for the plantar common digital nerve injection, rather than for an injection targeting a different peripheral nerve. The procedure has a 0-day global period, so same-day preoperative and postoperative care is included. For bilateral reporting, modifier 50 is paid at 150%. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others at 50%. An assistant is paid only when medical necessity is documented; co-surgeons and team surgery are not permitted.
