Policy: 201208 Initial Effective Date: 01/01/2013 SUBJECT: Lumbar Spinal Fusion Annual Review Date: 04/25/2018 Last Revised Date: 011/02/2020 Prior approval is required for some or all procedure codes listed in this Corporate Medical Policy. Some or all procedure codes listed in this Corporate Medical Policy may be considered experimental/investigational. Definition: Lumbar spinal fusion (interbody fusion, lumbar arthrodesis) is the surgical immobilization (fixation) of two or more adjacent vertebral bodies of the lumbar spine. Although decreased spinal flexibility may result, vertebral fusion is designed to alleviate pain, improve function, restore stability and produce a more anatomically correct vertebral alignment. Conditions that may require lumbar spinal fusion include, but are not limited to: spinal instability, spinal stenosis, spinal cord compression and vertebral destruction caused by infection and tumors. Several surgical approaches and techniques exist in treatment of spinal conditions. Minimally invasive approaches and devices, e.g., Anterior Lumbar Interbody Fusion (ALIF®), Axial Lumbar Interbody Fusion (AxiaLIF, TranS1®), Direct Lateral Interbody Fusion (DLIF), Extreme Lateral Interbody Fusion (XLIF), Maximal Access Surgery® MAS Interlaminar Lumbar Instrumented Fusion (ILIF™) (e.g., Coflex-F® Implant System), Laparoscopic Anterior Lumbar Interbody Fusion (LALIF), Posterior Lumbar Interbody Fusion (PLIF), Posterior Lumbar Intertransverse Process Fusion (PLIT), Transforaminal Lumbar Interbody Fusion (TLIF), Dynamic Spine Stabilization Device Systems (e.g., Dynesys®, Stabilimax NZ®) and Total Facet Arthroplasty (e.g., Total Facet Arthroplasty System™, SPIRE™ Stabilization System) can also be utilized as an alternative to or part of spinal fusion surgery. Medical Necessity: The Company considers lumbar spinal fusion (CPT 22533, 22534, 22558, 22585, 22612, 22614, 22630, 22632, 22633, 22634, 22800, 22808, 22840, 22845, 22853, 22854, 22859 and applicable ICD-10-CM Procedure Codes) medically necessary and eligible for reimbursement providing at least one of the following medical criteria is met: • Radiographic evidence (e.g., x-ray, computed tomography scan, magnetic resonance imaging) of lumbar spinal instability and at least one of the following: 1.
