CPT Code 62321: Cervical or Thoracic Epidural Steroid Injection

CPT code 62321 refers to an injection of a diagnostic or therapeutic substance, such as an anesthetic or steroid, into the interlaminar epidural or subarachnoid space in the cervical or thoracic spine, with imaging guidance (e.g., fluoroscopy or CT).

According to the Local Coverage Determination (LCD), CPT code 62321 can only be reported for one spinal level per session. Additionally, no more than four epidural injection sessions (using this code) can be reported per spinal region in 12 months, regardless of the number of levels treated.

The key difference is that CPT code 62321 applies to cervical or thoracic epidural injections, while CPT code 62323 is for lumbar or sacral epidural injections. Both codes are used for similar procedures but target different areas of the spine with imaging guidance.
