When deciding coverage, the member specific benefit plan document must be referenced. The terms of the member specific benefit plan document [e.g., Certificate of Coverage (COC), Schedule of Benefits (SOB), and/or Summary Plan Description (SPD)] may differ greatly from the standard benefit plan upon which this Medical Policy is based. In the event of a conflict, the member specific benefit plan document supersedes this Medical Policy. All reviewers must first identify member eligibility, any federal or state regulatory requirements, and the member specific benefit plan coverage prior to use of this Medical Policy. Other Policies and Coverage Determination Guidelines may apply. UnitedHealthcare reserves the right, in its sole discretion, to modify its Policies and Guidelines as necessary. This Medical Policy is provided for informational purposes. It does not constitute medical advice. UnitedHealthcare may also use tools developed by third parties, such as the MCG Care Guidelines, to assist us in administering health benefits. The MCG Care Guidelines are intended to be used in connection with the independent professional medical judgment of a qualified health care provider and do not constitute the practice of medicine or medical advice. BENEFIT CONSIDERATIONS Before using this policy, please check the member specific benefit plan document and any federal or state mandates, if applicable. Essential Health Benefits for Individual and Small Group For plan years beginning on or after January 1, 2014, the Affordable Care Act of 2010 (ACA) requires fully insured non-grandfathered individual and small group plans (inside and outside of Exchanges) to provide coverage for ten categories of Essential Health Benefits ( EHBs ). Large group plans (both self-funded and fully insured), and small group ASO plans, are not subject to the requirement to offer coverage for EHBs. However, if such plans choose to provide coverage for benefits which are deemed EHBs, the ACA requires all dollar limits on those benefits to be removed on all Grandfathered and Non-Grandfathered plans. The determination of which benefits constitute EHBs is made on a state by state basis. As such, when using this policy, it is important to refer to the member specific benefit plan document to determine benefit coverage. COVERAGE RATIONALE Spinal fusion using extreme lateral interbody fusion (XLIF ) or direct lateral interbody fusion (DLIF) is proven. For information regarding medical necessity review, when applicable, see the following MCG Care Guidelines, 21st edition, 2017: Cervical Diskectomy or Microdiskectomy, Foraminotomy, Laminotomy, S-310 (ISC) Lumbar Diskectomy, Foraminotomy, or Laminotomy S-810 (ISC) Cervical Laminectomy S-340 (ISC) Surgical Treatment for Spine Pain Page 1 of 32

2 Lumbar Laminectomy S-830 (ISC) Cervical Fusion, Anterior S-320 (ISC) Cervical Fusion, Posterior S-330 (ISC) Lumbar Fusion S-820 (ISC) The following spinal procedures are unproven: Spinal fusion, when performed via the following methods o Laparoscopic anterior lumbar interbody fusion (LALIF) o Transforaminal lumbar interbody fusion (TLIF) which utilizes only endoscopy visualization (such as a percutaneous incision with video visualization) o Axial lumbar interbody fusion (AxiaLIF ) o Interlaminar lumbar instrumented fusion (ILIF) (e.g., Coflex-F ) This includes interbody cages, screws, and pedicle screw fixation devices with any of the above procedures. Clinical evidence is limited primarily to retrospective studies and case series. Randomized, controlled trials comparing these procedures to standard procedures are needed to determine impact on health outcomes and long-term efficacy. Spinal decompression and interspinous process decompression systems o Interspinous process decompression (IPD) systems, for the treatment of spinal stenosis o Minimally invasive lumbar decompression (MILD ) Current clinical evidence is insufficient to permit conclusions about whether any beneficial effect from minimally invasive lumbar decompression provides a significant advantage over surgical decompression. In addition, the complication rates and reoperation rates for this procedure compared with those of decompression surgery is unknown. Spinal stabilization o o o Stabilization systems for the treatment of degenerative spondylolisthesis Total facet joint arthroplasty, including facetectomy, laminectomy, foraminotomy, vertebral column fixation The current published evidence is insufficient to determine whether facet arthroplasty is as effective or as safe as spinal fusion, the current standard for surgical treatment of degenerative disc disease. In addition, no devices have received approval from the U.S. Food and Drug Administration for use outside the clinical trial setting. Percutaneous sacral augmentation (sacroplasty) with or without a balloon or bone cement for the treatment of back pain The available clinical evidence shows that percutaneous sacroplasty, may alleviate the pain and functional impairment of sacral insufficiency fractures (SIF) in most patients with few and predominantly minor adverse effects, suggesting that this procedure may be relatively safe and efficacious for treatment of SIF. Despite these promising findings, the overall quality of the body of evidence is low given that the available studies were limited by methodological flaws (e.g., retrospective design, small sample size, subjective outcome measures, lack of a control group, and inadequate follow-up). Before reliable recommendations may be made, higher-quality studies are required that entail large populations with sufficient statistical power. Stand-alone facet fusion without an accompanying decompressive procedure o This includes procedures performed with or without bone grafting and/or the use of posterior intrafacet implants such as fixation systems, facet screw systems or anti-migration dowels. Clinical evidence is limited primarily to case series and nonrandomized studies. Randomized, controlled trials comparing facet fusion to standard procedures are needed to determine impact on health outcomes and long-term efficacy. APPLICABLE CODES The following list(s) of procedure and/or diagnosis codes is provided for reference purposes only and may not be all inclusive. Listing of a code in this policy does not imply that the service described by the code is a covered or noncovered health service. Benefit coverage for health services is determined by the member specific benefit plan document and applicable laws that may require coverage for a specific service. The inclusion of a code does not imply any right to reimbursement or guarantee claim payment. Other Policies and Coverage Determination Guidelines may apply. Coding Clarification: The North American Spine Society (NASS) recommends that anterior or anterolateral approach techniques performed via an open approach should be billed with CPT codes These codes should be used to report the use of extreme lateral interbody fusion (XLIF) and direct lateral interbody fusion (DLIF) procedures (NASS, 2010). Laparoscopic approaches should be billed with an unlisted procedure code. Surgical Treatment for Spine Pain Page 2 of 32

It may be caused by trauma, tumor, infection, or congenital defects but is predominately caused by degenerative changes in the intervertebral discs and the ligaments and bone structures of the spine. These changes typically begin with a breakdown of the discs with consequent collapse of disc space, which leads to disc bulge and herniation, and transference of weight to the facet joints. This in turn leads to cartilage erosion and compensatory growth of new bone (bone spurs) over the facet joints as well as thickening of ligaments around the facet joints to help support the vertebrae (AAOS, 2013). Surgery may be performed if symptoms do not respond adequately to nonsurgical approaches and continue to cause poor quality of life (AANS, 2011; Shamie, 2011; AAOS, 2013). Spinal procedures with the goal of decompression and/or stabilization can be done with an open surgical approach or minimally invasively. Open procedures require larger incisions, muscle stripping, longer hospitalization and subsequent increased recovery time. There is no standard definition of minimally invasive surgical techniques. Minimally invasive may include the use of smaller incisions, stab incisions or portals for instrumentation. The advantages of using a smaller surgical incision are reduced postoperative pain, diminished blood loss, faster recovery and reduced hospital stays. Spinal Fusion Spinal fusion, also called arthrodesis, is a surgical technique that may be done as an open or minimally invasive procedure. There are many different approaches to spinal fusion, but all techniques involve removing the disc between two or more vertebrae and fusing the adjacent vertebrae together using bone grafts and/or spacers placed where the disc used to be. Spacers can be made of bone or bone substitutes, metal (titanium), carbon fiber, polymers or bioresorbable materials and are often supported by plates, screws, rods and/or cages. Several minimally invasive spinal fusion procedures have been developed and include the following: Laparoscopic anterior lumbar interbody fusion (LALIF) is a minimally invasive alternative to an open surgical approach to spinal fusion. The vertebrae are reached through an incision in the lower abdomen or side. This method employs a laparoscope to remove the diseased disc and insert an implant (i.e., rhbmp, autogenous bone, cages or fixation devices) into the disc space intended to stabilize and promote fusion. Transforaminal lumbar interbody fusion (TLIF) is a modification of the posterior lumbar interbody fusion (PLIF) that gives unilateral access to the disc space to allow for fusion of the front and back of the lumbar spine. The front portion of the spine is stabilized with the use of an interbody spacer and bone graft. The back portion is secured with pedicle screws, rods and additional bone graft. TLIF is performed through a posterior incision over the lumbar spine and can be done as an open or percutaneous procedure. Axial lumbar interbody fusion (AxiaLIF ), also called trans-sacral, transaxial or para-coccygeal interbody fusion, is a minimally invasive technique used in L5-S1 (presacral) spinal fusions. The technique provides access to the spine along the long axis of the spine, as opposed to anterior, posterior or lateral approaches. The surgeon enters the back through a very small incision next to the tailbone and the abnormal disc is taken out. Then a bone graft is placed where the abnormal disc was and is supplemented with a large metal screw. Sometimes, additional, smaller screws are placed through another small incision higher on the back for extra stability. Interlaminar lumbar instrumented fusion (ILIF) combines direct neural decompression with an allograft interspinous spacer to maintain the segmental distraction, and a spinous process fixation plate, or other fixation options such as cortical pedicle screws to maintain stability for eventual segmental fusion. (e.g., Coflex-F ) Williams and Park (2007) address the presumed superiority of one minimally invasive approach over another as follows: At this time, no particular approach and no particular minimally invasive technique of stabilization has been shown to be superior to others, and there are several good studies that show statistical equivalency between anterior lumbar antibody [sic] fusion (ALIF), posterior lumbar antibody [sic] fusion (PLIF), and posterolateral fusion with instrumentation. Spinal Decompression and Interspinous Spacers Interspinous spacers are small devices implanted between the vertebral spinous processes. After implantation the device is opened or expanded to distract (open) the neural foramen and decompress the nerves. Interlaminar spacers are implanted midline between adjacent lamina and spinous processes to provide dynamic stabilization following decompressive surgery.

11 The following is a list of some of the minimally invasive procedures that decompress (reduce) the pressure on the spinal or nerve root: The X-STOP Interspinous Process Decompression (IPD) System has been developed as part of a minimally invasive surgical method to treat lumbar spinal stenosis, an abnormal narrowing or constriction of spaces that provide pathways for spinal nerves. For many patients, this device can be implanted by an orthopedic surgeon under local anesthesia as an outpatient procedure, although in some circumstances, the physician may prefer to admit the patient for an inpatient stay (Zucherman et al., Hayes 2014). The Coflex Interlaminar Stabilization Device is an implantable titanium interspinous process device (IPD) that reduces the amount of lumbar spinal extension possible while preserving range of motion in flexion, axial rotation, and lateral bending. The coflex is a U-shaped device with 2 pair of serrated wings extending from the upper and lower long arms of the U. The U portion is inserted horizontally between 2 adjacent spinous processes (bones) in the back of the spine, and the wings are crimped over bone to hold the implant in place. The device is implanted after decompression of stenosis at the affected level(s). Image-guided minimally invasive lumbar decompression (MILD ) is a percutaneous procedure for decompression of the central spinal canal in patients with lumbar spinal stenosis. The mild Device Kit (Vertos Medical Inc.) is a sterile, single-use system of surgical instruments. After filling the epidural space with contrast medium, a cannula is clamped in place with a back plate and a rongeur, tissue sculpter and trocar are used to resect thickened ligamentum flavum and small pieces of lamina. The process may be repeated on the opposite side for bilateral decompression. Spinal Stabilization The use of dynamic stabilization devices has been proposed as an alternative to rigid stabilization devices. Like standard frame devices, these devices are fixed in place using pedicle screws which are attached to the vertebral bodies adjacent to the intervertebral space being fused. Unlike standard frames, these devices are designed using flexible materials which purport to stabilize the joint while still providing some measure of flexibility. The Dynesys Dynamic Stabilization System was designed as a means to provide stability during spinal fusion to stabilize the spine; however, is currently being investigated as a substitute for spinal fusion. The Dynesys Dynamic Stabilization System is intended for use in skeletally mature patients as an adjunct to fusion in the treatment of the following acute and chronic instabilities or deformities of the lumbar or sacral spine: degenerative spondylolisthesis with objective evidence of neurologic impairment, fracture dislocation, scoliosis, kyphosis, spinal tumor, and failed previous fusion (pseudoarthrosis). Total facet joint arthroplasty, such as the Total Facet Arthroplasty System (TFAS ) is a non-fusion spinal implant developed to treat patients with moderate to severe spinal stenosis. TFAS replaces the diseased facets (and lamina, if necessary) following surgical removal. Percutaneous sacroplasty is a minimally invasive surgical treatment that attempts to repair sacral insufficiency fractures using polymethylmethacrylate (PMMA) bone cement. Sacral insufficiency fractures have traditionally been treated with conservative measures, including bed rest, analgesics, orthoses/corsets and physical therapy. In some cases pain persists, and is refractory to these measures. These patients are predominately elderly, and hardware implantation may not be possible in weakened bone. For this procedure, 2 thin, hollow tubes are placed in the lower back, over the left half and right half of the sacrum, guided by images from x-rays or computed tomography scans. The surgeon then advances a needle through each tube to the site of the sacral fracture and injects 2 to 5 ml of bone cement (Hayes, 2014). Facet Fusion Facet syndrome as a cause of low back pain is less common than degenerative disc disease and is not a clearly identified source of back pain. Facet joints are the articulations or connections between the vertebrae. Nociceptive nerve fibers have been identified in the facet joint capsules, in synovial tissue and in pericapsular tissue. It is hypothesized that increased motion and instability of the motion segments can lead to stress on the facet joint capsule, ultimately leading to the production of pain. Pain is characterized as worsening in extension and easing with flexion; it may radiate to the lateral buttock and thigh. Facet fusion is a procedure that uses an allograft to fuse the joint together to provide spinal column stability and pain reduction. Facet fusion has been proposed as a treatment option for individuals with facet joint pain that does not respond to conservative treatment. CLINICAL EVIDENCE Spinal Fusion Lumbar spinal fusion has been shown to result in reduced pain and improved function in select patients. In a review article by German et al. (2005) the author provides an overview of current minimally invasive lumbar fusion techniques. Pertinent literature and the authors' clinical experience were reviewed. Minimally invasive techniques have been developed for intertransverse process, posterior lumbar interbody, and transforaminal lumbar interbody fusions. It is emphasized that while these less-invasive procedures appear promising, the clinical results of these techniques Surgical Treatment for Spine Pain Page 11 of 32

12 remain preliminary with few long-term studies available for critical review. The author concluded that preliminary clinical evidence suggests that minimally invasive lumbar fusion techniques will benefit patients with spinal disorders. This study has a relatively short follow-up period. More long-term studies are still indicated. Laparoscopic Anterior Lumbar Interbody Fusion (LALIF) Evidence in the peer-reviewed scientific literature evaluating laparoscopic anterior lumbar interbody fusion is primarily in the form of prospective and retrospective case series, comparative trials, and nonrandomized trials. Currently, the published, peer-reviewed scientific literature does not allow strong conclusions regarding the overall benefit and longterm efficacy of the laparoscopic approach compared to open spinal fusion. There is insufficient new published evidence since June 19, 2007, to compel a reassessment of the safety and/or impact on health outcomes or patient management of laparoscopic ALIF for the treatment of low back pain. (Hayes, 2015) Frantzides et al. (2006) completed a retrospective analysis of consecutive patients who underwent L5-S1 laparoscopic ALIF between February 1998 and August Twenty-eight patients underwent L5-S1 LAIF (15 males and 13 females). The mean age was 43 years (range, 26 to 67). The authors concluded that ALIF is feasible and safe with all the advantages of minimally invasive surgery. Fusion rates and pain improvement were comparable to those with an open repair. However, the small numbers of patients in the study, and the specific experience of the surgeons with this procedure would make it difficult to generalize this result to a larger population. Inamasu and Guiot (2005) reviewed the literature on the outcomes of LALIF. Several comparative studies showed that at the L5-S1 disc level, there was no marked difference between LALIF and the open or mini-open ALIF in terms of short-term efficacy, i. e., operative time, blood loss and length of hospital stay. With regard to the complication rate, however, there was a higher incidence of retrograde ejaculation in LALIF. At the L4-L5 and L4-L5/L5-S1 disc levels, the complication rate and conversion rate to open surgery was high in LALIF, and many authors were not impressed with the LALIF at these levels. Several case series showed that the LALIF yielded excellent perioperative outcomes in the hands of experienced endoscopic spine surgeons at both the L5-S1 and L4-L5 disc levels. No conclusion regarding either the superiority or inferiority of LALIF to the open or mini-open ALIF can be drawn, because of the lack of data with a high-level of evidence. Chung et al. (2003) compared perioperative parameters and minimum 2-year follow-up outcome for laparoscopic and open anterior surgical approach for L5-S1 fusion. The data of 54 consecutive patients who underwent anterior lumbar interbody fusion (ALIF) of L5-S1 from 1997 to 1999 were collected prospectively. More than 2-years' follow-up data were available for 47 of these patients. In all cases, carbon cage and autologous bone graft were used for fusion. Twenty-five patients underwent a laparoscopic procedure and 22 an open mini-alif. Three laparoscopic procedures were converted to open ones. For perioperative parameters only, the operative time was statistically different (P=0.001), while length of postoperative hospital stay and blood loss were not. The incidence of operative complications was three in the laparoscopic group and two in the open mini-alif group. After a follow-up period of at least 2 years, the two groups showed no statistical difference in pain, measured by visual analog scale, in the Oswestry Disability Index or in the Patient Satisfaction Index. The fusion rate was 91% in both groups. The laparoscopic ALIF for L5-S1 showed similar clinical and radiological outcome when compared with open mini-alif, but significant advantages were not identified. In a multicenter study, prospective study by Regan et al. (1999), 240 patients underwent LALIF. This cohort was compared with 591 consecutive patients undergoing open anterior fusion using a retroperitoneal approach. The laparoscopy group had shorter hospital stays and reduced blood loss but had increased operative time. Operative time improved in the laparoscopy group as surgeons' experience increased. Operative complications were comparable in both groups, with an occurrence of 4.2% in the open approach and 4.9% in the laparoscopic approach. Overall, the device-related reoperation rate was higher in the laparoscopy group (4.7% vs. 2.3%), primarily as a result of intraoperative disc herniation. Conversion to open procedure in the laparoscopy group was 10%, with most cases predictable and preventable. The laparoscopic procedure is associated with a learning curve, but once mastered it is effective and safe when compared with open techniques of fusion. Kaiser et al. (2002) conducted a retrospective review of 98 patients who underwent ALIF procedures between 1996 and 2001 in which either a mini-open or a laparoscopic approach was used. Patient demographics, intraoperative parameters, length of hospitalization, and technique-related complications associated with the use of these two approaches were compared. The subset of patients who underwent L5-S1 ALIF procedures was analyzed separately. A laparoscopic approach was used in 47 of these patients, and the mini-open technique was used in the other 51 patients. The authors concluded that both the laparoscopic and mini-open techniques are effective approaches to use when performing ALIF procedures. On the basis of the data obtained in this retrospective review, the laparoscopic approach does not seem to have a definitive advantage over the mini-open exposure, particularly in an L5-S1 ALIF Surgical Treatment for Spine Pain Page 12 of 32
