Revised: August 2016 


Benefit Application:

Benefit determinations are based on the applicable contract language in effect at the time the services were rendered. Exclusions, limitations or exceptions may apply. Benefits may vary based on contract, and individual member benefits must be verified. Wellmark determines medical necessity only if the benefit exists and no contract exclusions are applicable. This medical policy may not apply to FEP. Benefits are determined by the Federal Employee Program.

This Medical Policy document describes the status of medical technology at the time the document was developed. Since that time, new technology may have emerged or new medical literature may have been published. This Medical Policy will be reviewed regularly and be updated as scientific and medical literature becomes available.

Description:

A variety of terms may be used to describe percutaneous radiofrequency denervation including radiofrequency ablation (RFA), non-pulsed radiofrequency, radiofrequency neuroablation, radiofrequency lesioning, radiofrequency neurotomy, radiofrequency facet rhizotomy and radiofrequency articular rhizolysis.

 

The facet joints, also known as apophyseal or zygapophyseal joints, are formed by the superior and inferior articular processes of sequential vertebrae. The nerves that communicate with these joints sometimes become inflamed or impinged, which leads to facet joint pain.

   

Percutaneous radiofrequency facet joint ablation/denervation is used to treat neck or back pain originating in the facet joints with degenerative changes. Diagnosis of facet joint pain is confirmed by a positive response from at least two diagnostic blocks i.e. facet joint injections or medial branch block. The goal of facet joint denervation is long-term pain relief. However, the nerve(s) regenerate, and repeat procedures may be required.

 

Radiofrequency facet joint denervation is performed under local anesthetic with fluoroscopic guidance. A percutaneously introduced electrode applies heat from radio waves to selectively destroy sensory afferent nerve fibers, thereby interrupting pain signals from a specific site. A minimum of two levels must be addressed to ablate/denervate a single joint. Radiofreqency (RF) denervation is directed at each of the levels to be lesioned. Destruction of the nerve may be permanent or temporary. In some cases, the treated nerve repairs itself and becomes less irritable, thus resulting in continued resolution of the pain. In cases where the pain returns, the procedure can be repeated in the same joint.

 

Based on the peer reviewed medical literature there is insufficient evidence of high quality data evaluating the safety and effectiveness of treatment with radiofrequency ablation/denervation in the thoracic facet joints for chronic pain.

 

Additional well designed comparative studies are needed to determine the effects of this technology on health outcomes.  Therefore, radiofrequency denervation for thoracic facet joint pain is considered investigational.

 

Radiofrequency Ablation/Denervation of Sacroiliac Joint Pain
Similar to other structures in the spine, it is assumed that the sacroiliac joint may be a source of low back pain. In fact, before 1928, the sacroiliac joint was thought to be the most common cause of sciatica. In 1928, as the role of intervertebral disc became more clear, and from that point forward, the sacroiliac joint received less research attention.

 

Research into sacroiliac joint pain has been thwarted by any criterion standard to measure its prevalence and against which various clinical examinations can be validated. For example, sacroiliac joint pain is typically without any consistent, demonstrable radiography or laboratory features and most commonly exists in the setting of morphologically normal joints. Clinical tests for sacroiliac joint pain may include various movement tests, palpation to detect tenderness, and pain descriptions by the patient. Further confounding study of the sacroiliac joint is that multiple structures, such as posterior facet joints and lumbar discs, may refer pain the area surrounding the sacroiliac joint. Treatments being investigated for sacroiliac joint pain include radiofrequency ablation/denervation.

 

The literature on radiofrequency ablation/denervation of the sacroiliac joint is limited. There are two small randomized controlled trials (RCTs) that report short term benefit, but these are insufficient to determine the overall effect on health outcomes. Further high quality controlled trials are needed that compare this procedure in defined populations with placebo and with alternative treatments. The current evidence on sacroiliac joint radiofrequency ablation/denervation is insufficient to permit conclusions regarding the effect of this procedure on health outcomes and therefore is considered investigational for the treatment of sacroiliac joint pain.  

 

Radiofrequency Ablation/Denervation of Cervical Facet Joints for Occipital Neuralgia and Chronic Headaches 

The available evidence from the smaller number of studies published in the peer reviewed literature is insufficient to conclude that ablative treatment to the cervical facet joint is an effective treatment for occipital neuralgia and chronic headaches (including but not limited to cervicogenic headache, migraines, cluster headaches, tension headaches). The limited data suggests that some patients may obtain short term relief from the use of ablative treatment along with the reduction of pain, however, the long term efficacy remains unknown.

 

Alternative Methods of Ablation/Denervation in the Treatment of Facet Joint and Sacroiliac Joint Pain   

Alternative methods of ablation/denervation in the treatment of facet joint and sacroiliac joint pain including but not limited to the following: laser denervation, chemical neurolysis (chemodenervation) (e.g. alcohol, phenol or high concentrations local anesthetic), cryodenervation (cryoablation), pulsed radiofrequency denervation and cooled radiofrequency denervation based on the peer reviewed medical literature long term controlled studies are lacking, additional studies are needed to establish safety and long term efficacy to support the use of these methods and therefore, these techniques are considered investigational.  

 

Practice Guidelines and Position Statements 

 

The American Society of Interventional Pain Physicians (ASIPP)
Update of Comprehensive Evidence Based Guidelines for Interventional Techniques in Chronic Spinal Pain. 2013 Guidance and Recommendations:

 

Management of Neck Pain

 

Therapeutic Cervical Facet Joint Interventions

  • The evidence is fair for cervical radiofrequency neurotomy and cervical medial branch blocks, and limited for cervical intra-articular injections.
  • Conventional radiofrequency neurotomy or therapeutic facet joint nerve blocks are recommended in managing chronic neck pain after the appropriate diagnosis from controlled diagnostic blocks. 

Management of Low Back Pain

 

Therapeutic Lumbar Facet Joint Interventions:

  • The evidence for lumbar conventional radiofrequency neurotomy is good; limited for pulsed radiofrequency neurotomy; fair to good for lumbar facet joint nerve blocks, and limited for intra-articular blocks.

Therapeutic Sacroiliac Joint Interventions

  • The evidence is limited for both pulsed radiofrequency and conventional radiofrequency neurotomy  

Management of Thoracic Pain

  • Radiofrequency neurotomy and conventional radiofrequency neurotomy may be performed on emerging evidence.
 

American Academy of Neurology
In 2012 the American Academy of Neurology and the American Headache Society issued and evidence based guideline update: NSAIDs and other complementary treatments for episodic migraine prevention in adults which does not mention local injection therapies, ablative treatments, electrical stimulation or neurosurgeries as complimentary treatments for migraines.

 

Regulatory Status
A number of radiofrequency generators and probes have been cleared for marketing through the U.S. Food and Drug Administration’s (FDA) 510(k) process. One device, the Sinergy by Kimberly Clark/Baylis, is a water cooled single use probe that received FDA clearance in 2005, listing the Baylis Pain Management Probe as a predicate device. The intended use is in conjunction with a radiofrequency generator to create radiofrequency lesions in nervous tissue.

Radiofrequency ablation (RFA/denervation is considered investigational for the treatment of thoracic facet joint pain or sacroiliac joint pain.

 

The peer reviewed medical literature regarding radiofrequency ablation (RFA)/denervation for the treatment of thoracic facet joint and sacroiliac joint pain is limited, there is insufficient evidence regarding the safety and efficacy, and further high quality controlled trials are needed that compare these procedures in defined populations with placebo and with alternative treatments.  Therefore, radiofrequency ablation (RFA)/denervation for treatment of thoracic facet joint and sacroiliac joint pain is considered investigational.

 

Radiofrequency ablation (RFA) of the cervical facet joints for the treatment of chronic headaches (including but not limited to cervicogenic headache, migraines, cluster headaches, tension headaches) or occipital neuralgia is considered investigational because the safety and effectiveness for these indications has not been established.    

 

All other methods of  ablation/denervation for the treatment of chronic neck and spinal/back pain, including but not limited to facet joint or sacroiliac joint pain are considered investigation (not an all-inclusive list):

  • Laser denervation,
  • Chemical neurolysis (chemodenervation) (e.g. alcohol, phenol, or high concentrations local anesthetics)
  • Cryodenervation (cryoablation)
  • Cooled radiofrequency ablation/denervation
  • Pulsed radiofrequency ablation/denervation

Based on the peer reviewed medical literature there is insufficient evidence to evaluate the safety and effectiveness of these other methods of denervation for facet joint and sacroiliac joint pain.  Long term controlled studies are lacking and additional studies are needed to establish safety and long term efficacy to support the use of these methods in the treatment of facet joint and sacroiliac joint pain and therefore, these techniques are considered investigational.
