Look to these Codes on Paravertebral Facet Joint Injections

Remember, not all payers have identical approved diagnoses.

When a patient reports to the PM specialist for a paravertebral facet joint injection in the cervical/thoracic or lumbar/sacral areas, you'll report the service with one or more of the following codes, depending on encounter specifics:

  • 64490 - Injection(s), diagnostic or therapeutic agent, paravertebral facet (zygapophyseal) joint (or nerves innervating that joint) with image guidance (fluoroscopy or CT), cervical or thoracic; single level)
  • +64491 - ... second level (List separately in addition to code for primary procedure)  
  • + 64492 - ... third and any additional level(s) (List separately in addition to code for primary procedure)
  • 64493 - Injection(s), diagnostic or therapeutic agent, paravertebral facet (zygapophyseal) joint (or nerves innervating that joint) with image guidance (fluoroscopy or CT), lumbar or sacral; single level
  • +64494 - ... second level (List separately in addition to code for primary procedure)
  • + 64495 - ... third and any additional level(s) (List separately in addition to code for primary procedure).

While there is no single source of approved diagnosis codes for these injections, there are a few that are commonly attached to one or more of the above codes. Those ICD-10 codes include:

  • M25.511 - Pain in right shoulder
  • M25.512 - Pain in left shoulder
  • M25.521 - Pain in right elbow 
  • M25.522 - Pain in left elbow
  • M25.531 - Pain in right wrist
  • M25.532 - Pain in left wrist
  • M25.551 - Pain in right hip
  • M25.552 - Pain in left hip
  • M25.571 - Pain in right ankle and joints of right foot
  • M25.572 - Pain in left ankle and joints of left foot
  • M47.14 - Other spondylosis with myelopathy, thoracic region
  • M47.812 - Spondylosis without myelopathy or radiculopathy, cervical region
  • M47.817 - Spondylosis without myelopathy or radiculopathy, lumbosacral region
  • M47.892 - Other spondylosis, cervical region

  • M47.9 - Spondylosis, unspecified
  • M54.2 - Cervicalgia
  • M54.5 - Low back pain
  • M96.1 - Postlaminectomy syndrome, not elsewhere classified.

Remember: This is not a complete, or approved, list of ICD-10 codes that prove medical necessity for paravertebral facet joint injections. It is merely a guide to give you an idea of the types of diagnoses you might see with 64490 through +64495.

For a list of approved diagnosis codes for the 64490 through +64495 codes, consult with each payer individually.
