Interspinous and Interlaminar Stabilization/Distraction Devices (Spacers); Interspinous Fixation (Fusion) Devices
DESCRIPTION
Interspinous and Interlaminar Stabilization/Distraction Devices (Spacers)
Interspinous and interlaminar implants (spacers) are proposed to stabilize or distract the adjacent lamina and/or spinous processes and restrict extension to reduce pain in individuals with lumbar spinal stenosis and neurogenic claudication. Interspinous spacers are small devices implanted between the vertebral spinous processes. Interlaminar spacers are implanted between adjacent lamina and spinous processes purportedly to provide dynamic stabilization either following decompressive surgery or as an alternative to decompressive surgery.
Interspinous Fixation (Fusion) Devices
Interspinous fixation (fusion) devices are being developed to aid in the stabilization of the spine. These devices are being evaluated as alternatives to pedicle screw and rod constructs in combination with interbody fusion. These devices differ from interspinous process spacer devices in that they are used for fixation rather than for motion preservation.
Note: This medical policy does not apply to stand-alone cages (see additional information for examples)
POLICY
Use of interspinous stabilization/distraction devices (spacers) for all indications, including, but not limited to, use as a treatment for neurogenic intermittent claudication is considered investigational.
Use of interlaminar stabilization/distraction devices (spacers) for all indications, including, but not limited to, use following decompressive surgery is considered investigational.
Use of interspinous fixation (fusion) devices for all indications, including, but not limited to, use in combination with interbody fusion or alone for decompression in individuals with spinal stenosis, is considered investigational.
IMPORTANT REMINDERS
Any specific products referenced in this policy are just examples and are intended for illustrative purposes only. It is not intended to be a recommendation of one product over another, and is not intended to represent a complete listing of all products available. These examples are contained in the parenthetical e.g. statement.
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 or government program (e.g., TennCare), the express terms of the health plan or government program will govern.
ADDITIONAL INFORMATION
