Nervous system code changes 2021

There are five revised codes and four deleted codes from the Nervous system of code set 2021. The deleted codes include CPT 63180 and 63182 which represents laminectomy with sectioning of the dentate ligaments in the cervical region. Other deleted codes would include CPT 61870 which is used to report implantation of cortical neurostimulators electrodes requiring Craniectomy and CPT 62163 which describes retrieval of intracranial foreign body via neuroendoscopy. These codes were deleted due to low utilization.

The revisions are made under the “Extracranial Nerves, Peripheral Nerves and Autonomic Nervous system, Introduction/Injection of Anesthetic Agent(Nerve block), Diagnostic or Therapeutic subsection. The revised codes get the addition of (s) and punctuation changes that will make plantar common digital injections (64455) and transforaminal epidural injections (64479-64484) as child codes to the parent code 64400. Revised codes are given as below:

  • 64455: Injection(s), anesthetic agent(s), and/or steroid; plantar common digital nerve(s) (e.g., Morton’s neuroma)
  • 64479: Injection(s), anesthetic agent(s), and/or steroid; transforaminal epidural, with imaging guidance (fluoroscopy or CT), cervical or thoracic, single level
  • 64480: Injection(s), anesthetic agent(s), and/or steroid; transforaminal epidural, with imaging guidance (fluoroscopy or CT), cervical or thoracic, each additional level (List separately in addition to code for primary procedure)
