Summary & Overview
CPT 64633: Neurolytic Destruction of Cervical/Thoracic Facet Joint Nerves
CPT code 64633 is a key billing code for pain management specialists performing neurolytic destruction of paravertebral facet joint nerves in the cervical or thoracic spine. This procedure, guided by imaging such as fluoroscopy or CT, is widely used to treat chronic pain conditions related to facet joint dysfunction. The code is relevant for physicians in pain medicine, physical medicine and rehabilitation, and internal medicine who provide interventional spine procedures in ambulatory surgical centers or office settings with imaging capabilities.
Major national payers covering this code include Aetna, Blue Cross Blue Shield, Cigna Health, Medicare, and UnitedHealthcare. The publication provides an overview of payer coverage, clinical indications, and related billing codes, offering readers insight into current policy updates and reimbursement benchmarks. It also highlights common modifiers used in billing and the associated ICD-10 diagnoses for spondylosis and other dorsopathies. Readers will gain a comprehensive understanding of the clinical context, payer landscape, and coding nuances for CPT 64633, supporting informed decision-making in pain management billing and compliance.
CPT Code Overview
CPT code 64633 describes the destruction of paravertebral facet joint nerve(s) in the cervical or thoracic regions using a neurolytic agent, such as chemical, thermal, electrical, or radiofrequency methods. This procedure is performed with imaging guidance, typically fluoroscopy or CT, to ensure precision. It is commonly utilized in pain management and interventional spine procedures to address chronic pain associated with facet joint pathology. The typical site of service includes ambulatory surgical centers or office settings equipped with imaging capabilities, such as POS 11 or ASC.
Clinical & Coding Specifications
Clinical Context
A typical patient scenario involves an adult presenting with chronic neck or upper back pain attributed to facet joint pathology, such as spondylosis or other specified dorsopathies in the cervical or thoracic regions. The patient has not responded adequately to conservative treatments like physical therapy or medications. After clinical evaluation and diagnostic imaging, the provider determines that destruction of the paravertebral facet joint nerve(s) using a neurolytic agent is indicated to manage pain. The procedure is performed in an ambulatory surgical center or office setting equipped with fluoroscopy or CT imaging guidance. The workflow includes pre-procedure assessment, imaging-guided localization of the target nerve(s), application of the neurolytic agent, and post-procedure monitoring.
Coding Specifications
| Modifier Code | Description | When to Use |
|---|---|---|
50 | Bilateral procedure | When the procedure is performed on both sides of the spine (left and right facet joints). |
LT | Left side | When the procedure is performed only on the left side. |
