Lysis of epidural adhesions involves passage of a catheter endoscopically or percutaneously into the epidural space, where it may be manipulated mechanically or injected with various agents (anesthetics, corticosteroids, hyaluronidase or saline) to break up adhesions. The procedure may be performed with fluoroscopic guidance under general anesthesia or conscious sedation. The procedure may be referred to as epidural adhesiolysis and has been investigated as a procedure to reduce or eliminate adhesions, fibrosis, or scars which most commonly occur as a complication of spinal surgery and may be included under the diagnosis of “failed back surgery syndrome”. Symptoms of epidural adhesions can include low back pain, radicular pain, muscular spasms and contractures, sphincter disturbances, and motor/sensory disturbances.
Endoscopic epidurolysis is also being investigated for the treatment of degenerative chronic low back pain, including spondylolisthesis, stenosis and hernia associated with radiculopathy. Along with mechanical adhesiolysis, hyaluronidase, ciprofloxacin and ozone have been applied.
Lysis of epidural adhesions, with or without endoscopic guidance, is considered investigational.

We develop Medical Policies to provide guidance to Members and Providers. This Medical Policy relates only to the services or supplies described in it. The existence of a Medical Policy is not an authorization, certification, explanation of benefits or a contract for the service (or supply) that is referenced in the Medical Policy. For a determination of the benefits that a Member is entitled to receive under his or her health plan, the Member's health plan must be reviewed. If there is a conflict between the Medical Policy and a health plan, the express terms of the health plan will govern.
Published scientific evidence in the form of well-designed studies in peer-reviewed journals regarding the utilization of catheter based lysis of epidural adhesions continues to be lacking. There remains insufficient evidence to permit conclusions regarding this technology at this time.
