Destruction by Neurolytic Agent (eg, Chemical, Thermal, Electrical or Radiofrequency) and Chemodenervation Procedures on the Extracranial Nerves, Peripheral Nerves, and Autonomic Nervous System

Destruction by neurolytic agents and chemodenervation of extracranial, peripheral and autonomic nerves using chemical, thermal, electrical or radiofrequency methods. CPT codes 64600–64681 include somatic and sympathetic nerve neurolysis and related chemodenervation procedures across multiple targeted sites.

Excision Procedures on the Extracranial Nerves, Peripheral Nerves, and Autonomic Nervous System

Excision procedures on extracranial and peripheral nerves including removal of neuromas, nerve tumors, and segmental nerve excision. CPT codes 64774–64823 cover limited to extensive excisions of somatic and sympathetic nerve structures and associated operative descriptors.

Introduction/Injection of Anesthetic Agent (Nerve Block), Diagnostic or Therapeutic Procedures on the Extracranial Nerves, Peripheral Nerves, and Autonomic Nervous System

Introduction or injection of anesthetic agents for diagnostic or therapeutic nerve blocks targeting extracranial, peripheral and autonomic nerves. CPT codes 64400–64530 cover somatic and sympathetic nerve blocks, paravertebral injections, and related image‑guided or landmark techniques.

Neuroplasty (Exploration, Neurolysis or Nerve Decompression) Procedures on the Extracranial Nerves, Peripheral Nerves, and Autonomic Nervous System

Neuroplasty procedures including exploration, external neurolysis and surgical nerve decompression for peripheral nerve entrapment or scarring. CPT codes 64702–64728 describe neurolysis and decompression services for somatic nerves with varying anatomic targets and complexity.

Neurorrhaphy Procedures

Neurorrhaphy procedures for direct repair of severed peripheral nerves including end-to-end suture repair and coaptation. CPT codes 64831–64876 enumerate neurorrhaphy services by anatomic site and include single and multiple nerve repair descriptors.

Neurorrhaphy With Nerve Graft, Vein Graft or Conduit Procedures

Neurorrhaphy with nerve graft, vein graft, or conduit procedures involving interposition grafting for nerve reconstruction. CPT codes 64885–64913 cover autograft, allograft, vein grafting and conduit-assisted repairs across specified nerve sizes and lengths.

Neurostimulator Procedures on the Peripheral Nerves

Neurostimulator procedures on peripheral nerves including lead placement, generator implantation, revisions and removals for peripheral neuromodulation. CPT codes 64553–64598 include percutaneous and open peripheral nerve stimulator device procedures and supporting services.

Other Procedures of the Nervous System

Other miscellaneous procedures of the nervous system that do not fit standard categories, typically unlisted peripheral nerve or autonomic procedures. CPT code 64999 represents unlisted procedures of the nervous system and is used when no specific code applies.

Transection or Avulsion Procedures on the Extracranial Nerves, Peripheral Nerves, and Autonomic Nervous System

Transection or avulsion procedures on extracranial, peripheral and autonomic nerves typically for denervation or pain control. CPT codes 64732–64772 describe surgical nerve transection, avulsion and related denervation techniques across multiple anatomic sites.
