Submission Sponsor Stimwave Technologies Incorporated 1310 Park Central Boulevard South Pompano Beach FL, 33064 USA Phone: 800.965.5134 Fax: 800.965.5134 Member hasundergone careful screening, evaluation and diagnosis by a multidisciplinary team prior to implantation (Note: screening must include psychological as well as physical evaluations); Member does not have any untreated existing drug addiction problems (per American Society of Addiction Medicine (ASAM) guidelines). Not all experience is favorable. L8682 . According to the operative report, the Stimwave stimulator electrode was inserted and advanced through the epidural space parallel to the L4 body. Neuromodulation: Technology at the Neural Interface. The estimated median reduction of VAS was 61 % (range of 50 % to 100 %) with an estimated median reduction of morphine equivalent opioid use of 69 % (range of 25 % to 100 %) at the end of follow-up (less than 1 year to greater than 2years). Aetna considers a trial of percutaneousdorsal column stimulation medically necessary to predict whether a dorsal column stimulator will induce significant pain relief in members with chronic pain due to any of the following indications when the criteria listedbeloware met: Aetna considers implantation of a dorsal column stimulator (DCS) medically necessary for members who meet the above-listed criteria who haveexperienced significant pain reduction (50 % or more) with a 3- to 7-day trial of percutaneous spinal stimulation. 1993;307(6902):477-480. The authors concluded that in this study using PET, SCS increased glucose metabolism in RBI and peri-RBI areas. The update, supported by the body of clinical evidence, provides additional appropriate choices for physicians and the patients they treat, while also continuing to highlight our platforms ability to transform the lives of those suffering from chronic pain.. Appl Neurophysiol. The estimated potential maximal residual activity of the first FDG dose's contribution to the activity on the second scan wasless than or equal to14.3 +/- 4.6 %. J Diabetes Sci Technol. These investigators created evidence synthesis regarding the effects of electrical stimulation of DRG in the context of pain from in-vitro and in-vivo animal models, analyzed methodology and quality of studies in the field. In the era of evidence-based medicine, RCTs should be performed, but as visceral pain syndromes are so different in nature and expression, it is very difficult to select patient groups properly. When it comes to ABA therapy medical billing CPT Code 97151 can only be used for in-person face-to-face assessment with a patient, their parents, or another type of caregiver. Two patients with lower extremity CRPS, previously implanted with t-SCS systems, experienced relapses in the pain despite exhaustive re-programming. Meta-analysis was not possible because of heterogeneity and missing data. The implanted leads were then connected to the novel external stimulation device and patients were trialed for an additional 4 days. } The SF-MPQ and EuroQoL 5D questionnaires also showed that patients in the SCS group, unlike those in the control group, experienced reduced pain and improved health and QOL after 6 months of treatment. Anesthesiology. Neuromodulation. Sacral nerve root neuromodulation for bladder related symptoms and pain is the best studied technique, but all trials are observational. Subjects were treated during 45 days after which the stimulator was removed. Two reviewers independently screened the studies, extracted the data, and examined the quality of included trials. ICD-10-PCS procedure codes are used instead of CPT codes to report hospital inpatient procedure only. 1997;13(5):296-301. Over the next two to three days extensive testing with the temporary electrode is performed as an outpatient to measure the effectiveness and determine adequate positioning. 2021;2021:9969010. The assessment states: "Percutaneous electrical stimulation for the relief of otherwise refractory cancer pain has likewise not yet been evaluated in controlled trials. Electrical fields are generated that can selectively stimulate different parts of the dorsal root ganglia. Efficacious dorsal root ganglion stimulation for painful small fiber neuropathy: A case report. These investigators examined the effect of cervical SCS on cerebral glucose metabolism. Placement Of External Spinal Neurostimulator Generator - Find-a-code. J Neurosurg. Each patient underwent a clinical evaluation before and after real tDCS or sham stimulation. Trials were available for the neuropathic conditions FBSS and CRPS type I, and they suggested that SCS was more effective than conventional medical management (CMM) or re-operation in reducing pain. The authors concluded that these findings suggested that the use of SCS in the cervical spine was a medically effective method of pain management that satisfied and improved the QOL of most patients. At 1-year post-implantation, the average overall QOL was reported to be improved/greatly improved and patient satisfaction was rated satisfied/greatly satisfied. Robaina et al (1989) studied the use of SCS for relief of chronic pain in vasospastic disorders of the upper limbs. 2005;21(3):351-358. The pain intensity was reduced at 6 months, 1 and 2 years after implantation (p < 0.05). Neuromodulation. The authors concluded that current evidence does not support the use of amputation to improve either pain or function in CRPS. Case report. Nonsurgical interventional therapies for low back pain: A review of the evidence for an American Pain Society clinical practice guideline. the measurement of LBP relied only on the axial LBP patients in this study, not patients with both LBP and leg pain. Average VAS scores for patients treated with DTM SCS at 12 months were 1.74 for back pain and 1.45 for leg pain. They included 6 in-vitro and 8 in-vivo animal studies. 2018;18(2):205-213. From the time of diagnosis of last tumor relapse before re-irradiation, median OS was 39 months (95 % confidence intervals [CI]: 0 to 93) for the overall study group: 39 months (95 % CI: 9 to 69) for those with anaplastic gliomas and 16 months for the patient with glioblastoma. The authors concluded that the evolutionary pattern of the different parameters studied in these patients with FBSS did not differ according to their treatment by spinal stimulation, with CF or HF, in 1-year follow-up. Aetna considers the use of intra-operative motor evoked potentials (MEP) and somatosensory evoked potentials (SSEP)experimental and investigational forimplantation of spinal cord stimulators. In the case of group treatments, the protocol Patients with facial pain did not respond, while those with ischemic syndromes responded well. The authors stated that this study had several drawbacks. This result supports the potential usefulness of this neurosurgical technique as an adjuvant treatment in stroke and brain disorders that result from decreased blood flow and metabolism. Neuromodulation. The optimal positioning of the electrode is of major importance to the success of the treatment, but there is limited information available to-date regarding neuromodulation in visceral pain syndromes generally. Efficacy of spinal cord stimulation as adjuvant therapy for intractable angina pectoris: A prospective, randomized clinical study. 2015;18(7):592-598. Member experienced significant pain reduction (50 % or more) with a 3- to 7-day trial of percutaneous spinal stimulation. [email protected], Internet Explorer presents a security risk. Clavo and colleagues (2008) stated that syndromes resulting from decreased cerebral blood flow and metabolic activity have significant clinical and social repercussion. Furthermore, an UpToDate review on Symptom management of multiple sclerosis in adults (Olek et al, 2020) does not mention spinal cord stimulation as a management option. Trial stimulation was successful in 77 % of the SCS patients. These investigators reported a case of spinal cord stimulation (SCS) for chronic abdominal pain due to SOD. The authors concluded that very low-quality evidence, mainly due to imprecision and increased risk of bias, suggested that intermittent pneumatic compression and spinal cord stimulators may reduce the risk of amputations; evidence supporting other medical therapies is insufficient. Download PDF. Complications and adverse effects occurred in 64 % of the patients and consisted mainly of technical defects. Sanderson JE, Brooksby P, Waterhouse D, et al. They stated that the underlying pathophysiologic mechanisms remain to be elucidated; further experience with SCS in refractory gait disorders is needed. Furthermore, an UpToDate review on Treatment of chronic pelvic pain in women (Howard, 2013) states that In general, neuromodulation for CPP has not been well-studied. Findings from the studiesby Daousi et al (2005) as well as de Vos et al (2009) need to be validated by well-designed RCTs. Fishman M, Cordner H, Justiz R, et al. Although the exact mode of action of DCS in alleviating anginal pain is unclear, it has been suggested that its beneficial effects are achieved through an increase in oxygen supply to the myocardium in addition to its analgesic effect. A priori established subgroup analyses (combined versus single therapy; randomized versus non-randomized) were not statistically significant. Member has angiographically documented significant coronary artery disease and is not a suitable candidate for revascularization procedures such as coronary artery bypass grafting (CABG) or percutaneous transluminal coronary angioplasty (PTCA). In a sub-group analysis, the results with regard to global perceived effect (p = 0.02) and pain relief (p = 0.06) in 20 patients with an implant exceeded those in 13 patients who received PT. Trial evidence failed to demonstrate that pain relief in critical limb ischemia (CLI) was better for SCS than for CMM; however, it suggested that SCS was effective in delaying refractory angina pain onset during exercise at short-term follow-up, although not more so than coronary artery bypass grafting (CABG) for those patients eligible for that surgery. It is plausible that different results could have been obtained when using female rats based on evidence that suggested a gender-dependent mechanism on mechanical hypersensitivity in mice pain models, and gene expression in a rat pain model. Successful outcome, as judged by at least 50 % sustained analgesia and patient satisfaction with the result, was recorded in 53 % of patients at 2.2 years and 47 % of patients at 5.0 years. CPT/HCPCS Codes* Required Clinical Information . A total of 100 patients were randomized to either the DCS or CMM group. At the time of follow-up, only 12 % of patients were using analgesic medications with half of them at reduced dosage, compared with 74 % before the commencement of DCS therapy. Cervical spinal cord stimulation for pain: A report of 41 patients. Stimwave Technologies Incorporated Traditional 510(k) Premarket Submission SandShark Injectable Anchor (SIA) System Page 5-1 of 4 510(k) Summary for SandShark Injectable Anchor (SIA) System 1. We will immediately adhere to the new coding guideline issued by AHA; all StimQ PNS procedures will be coded as a 64555. This observation was supported by the findings of Anderson et al (1994) as well as Eliasson et al (1994). Therefore, the success rate could be influenced by factors associated with the lack of blinded treatments (e.g., spinal cord stimulation (SCS) subjects were less motivated to stay in the trial, uncontrolled differences in health care provider interactions). These investigators concluded that in severe cases of RSD and idiopathic Raynaud's disease, SCS is an alternative treatment that can be used as primary therapy or as secondary therapy after unsuccessful sympathectomy or sympathetic blocks. The investigators stated thata multimodal stimulation device has advantages. Aetna does not provide health care services and, therefore, cannot guarantee any results or outcomes. Maino et al (2017) noted that small fiber neuropathy is a disorder of the peripheral nerves with typical symptoms of burning, sharp, and shooting pain and sensory disturbances in the feet. No RCTs were identified; 14 sporadic case reports and review articles were excluded and 4 before-and-after case-series studies (92 participants) were included. Recent studies highlighting the importance of microglial cells in chronic pain and characterizing microglial activation transcriptomes have created a focus on microglia in pain research. Cochrane Database Syst Rev. Similarly, Sanderson et al (1992) noted that in 14 patients with severe intractable angina pectoris unresponsive to conventional therapies including bypass grafting, DCS resulted in a significant improvement of symptoms and a marked decrease in glycerol trinitrate consumption. By scrutinizing titles and abstracts, these investigators found 412 articles irrelevant to the analytical purpose of this systematic review due to different scopes of diseases or different methods of intervention (intra-thecal infusion system; oral medication) or aims other than pain control (spinal cord function monitoring, bladder function restoration or amelioration of organ metabolism). 2018;21(5):495-503. Patients underwent trial therapy where specifically designed leads were implanted at the target DRGs between T12 and L4. The study conducted by Perruchoud et al (2013) included 40 patients who achieved stable pain relief with CF-SCS and who were randomized to receive either HF-SCS at 5-kHz or a sham control (no stimulation after achieving paresthesia-free stimulation). Dyer MT, Goldsmith K, Khan S, et al. Ohnmeiss DD, Rashbaum RF, Bogdanffy GM. They were followed-up for 21 to 62 months. Georgiopoulos M, Katsakiori P, Kefalopoulou Z, et al. Before and during SCS, they had cerebral glucose metabolism evaluated using 18fluoro-2-deoxyglucose positron emission tomography (18FDG-PET) in the healthy cerebral hemisphere contralateral to the lesion area. Romano M, Zucco F, Allaria B, Grieco A. Epidural spinal cord stimulation in the treatment of refractory angina pectoris. Neuromodulation. Both patients were offered DRG stimulation as a means to salvage treatment. Thanks in advance! Abu Dabrh et al (2015) reviewed the existing evidence about various non-revascularization-based therapies used to treat patients with severe or critical limb ischemia (CLI) who are not candidates for surgical revascularization. The patient had a history of cholecystectomy and had suffered from chronic right upper quadrant abdominal pain. The StimRouter Reimbursement Group is committed to collaborating with healthcare professionals and patients to navigate through the reimbursement process. li.bullet { Secondary to persistent intractable pain, the patient was referred to the pain clinic for further evaluation. Twenty-four patients who received DCS+PT also underwent placement of a permanent spinal cord stimulator after successful test stimulation; the remaining 12 patients did not receive a permanent stimulator. In addition, subjects were required to maintain a stable regimen of pain medications through 3 months only, and the long-term results after 3 months may be affected by medication changes. Healthcare resource consumption data relating to screening, the use of the implantable generator in DCS patients, hospital stay, and drug and non-drug pain-related treatment were collected prospectively. In addition to a higher proportion of pain responders compared with pharmacotherapy or low-frequency SCS, 10-kHz SCS did not induce paresthesia, an advantage for PDN patients with uncomfortable paresthesia at baseline. Middleton P, Simpson B, Maddern G. Spinal cord stimulation (neurostimulation): An accelerated systematic review. However, 2 years later, the pain became intractable. The superiority of HF10 therapy over traditional SCS for leg and back pain was sustained through 12 months (p < 0.001). 2015;28(1):57-60. Last Review10/27/2022. Note: Lead and electrode replacement are not generally required at the time of generator replacement due to end of battery life. A tripolar SCS was implanted at the T8 level using one-eight contact and two-four contact percutaneous leads based on paresthesia reproduction of patient's areas of discomfort. The total sample comprised of 24 participants with SCI. A total of 7 studies including 31 patients met the inclusion criteria. The patient had no headache history prior to the accident. 2013;16(4):363-369; discussion 369. PRPR was 65.2 %, 62.4 %, and 71.9 % at 3-, 6-, and 12-month post-implantation, respectively. Walega D, Rosenow JM. This tripolar SCS provided relief of abdominal and thoracic pain, and better management of gastro-intestinal symptoms. In addition, 28 % of all subjects at last follow-up used opioid medications, compared to 40 % of all subjects before implantation of the DCS.

Costs and outcomes were assessed for each patient over their first 6-months of the trial. The mean VAS score before implantation (8.7) compared to VAS 12 months after implantation (4.0) was significantly lower (95 % CI: 3.9 to 5.4], p < 0.001). All 7 patients were successfully trialed with DRGS utilizing leads placed over the bilateral L1 and S2 DRG's -- to the authors knowledge, no publications describing either this particular lead configuration, or utilizing DRS on CPP, exist. The ischemic pain trials had small sample sizes, meaning that most may not have been adequately powered to detect clinically meaningful differences. The overall motor score of the Unified Parkinson's Disease Rating Scale in the on/off-stimulation condition remained unchanged in 6 patients and improved in 18 patients after SCS. (A trial of percutaneous spinal stimulation is considered medically necessary for members who meet the above-listed criteria, in order to predict whether a dorsal column stimulator will induce significant pain relief). Aetna considers DCS medically necessary DME for the management of intractable angina in members who are not surgical candidates and whose pain is unresponsive to all standard therapies when all of the following criteria are met: Contraindications to dorsal column stimulation for intractable angina are presented in an Appendix to the Background section of this CPB. Eur J Pain. Diabet Med. CPT codes not covered for indications listed in the CPB (not all-inclusive): Transcutaneous magnetic stimulation - No specific code: ICD-10 codes not covered for indications listed in the CPB (not all-inclusive): G89.21 - G89.29: Chronic pain: G89.4: Chronic pain syndrome: IB-Stem: CPT codes not covered for indications listed in the CPB . Identified studies on such targeted intra-spinal stimulation were reviewed and graded using Evidence Based Interventional Pain Medicine criteria. Concomitant reductions in overall pain, leg pain, pain interference, mood, and QOL were also found. Aetna considers dorsal column stimulation experimental and investigational for all other indications not mentioned abovebecause its effectiveness for other indications has not been established. Spinal cord stimulation (SCS) with anatomically guided (3D) neural targeting shows superior chronic axial low back pain relief compared to traditional SCS - LUMINA Study.

As clinical evidence accumulates and technological innovation improves patient outcomes, neuromodulatory techniques will be sought earlier in the treatment continuum to reduce the suffering for the many with otherwise intractable chronic pain. The stimulation devices used in PENS and PNT are not implanted, so CPT code 64590 is also not appropriate. Slangen et al (2014) stated that painful diabetic peripheral neuropathy (PDPN) is a common complication of diabetes mellitus (DM). These researchers included 19 studies that enrolled 2,779 patients. Modulation of microglial activation states by spinal cord stimulation in an animal model of neuropathic pain: Comparing high rate, low rate, and differential target multiplexed programming. Neuromodulation. Effect and safety of spinal cord stimulation for treatment of chronic pain caused by diabetic neuropathy. For the 10-kHz SCS plus CMM group, the mean pain VAS score was 7.6 cm (95 % CI: 7.3 to 7.9) at baseline and 1.7 cm (95 % CI: 1.3 to 2.1) at 6 months. Acta Neurochir Suppl. Vi, Yahoo, r en del av Yahoos varumrkesfamilj. Pain Med. Additional well-controlled clinical trials are necessary to assess the effectiveness of DRG in complex regional pain syndrome and in neuropathic pain of other etiologies. This would need multi-center trials to collect adequate numbers of patients to allow hypothesis testing to underpin recommendations for future evidence-based therapies. Feldman EL. Preliminary results of this study have been presented in abstract form (Hayek, et al., 2015),and study results have been published. Cameron T. Safety and efficacy of spinal cord stimulation for the treatment of chronic pain: A 20-year literature review. The National Institute for Health and Clinical Excellence (NICE)'s guideline on spinal cord stimulation for chronic neuropathicor ischemic pain (2008) recommended DCS for patients who continue to experience chronic neuropathic pain (e.g. Clin J Pain. The aim of this preliminary, non-randomized, study was to assess the clinical effect of SCS during brain re-irradiation and chemotherapy deployed for the treatment of recurrent HGG; the hypothesis being that an improvement in oxygenated blood supply would facilitate enhanced delivery of the scheduled therapy. The methodology utilized in this work followed a review process derived from evidence-based systematic review and meta-analysis of randomized trials described in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Van Buyten JP, Smet I, Liem L, et al. UpToDate [online serial]. Thomson S. Spinal cord stimulation for neuropathic pain. UpToDate [online serial]. In the RCT described above (NCT03228420), Peterson, et al. However, there is no consensus on patient selection or technical aspects of SCS for such pain. 2017;158(4):669-681. High-frequency 10-kHz spinal cord stimulation improves health-related quality of life in patients with. All subjects were implanted with DRG stimulation systems that had at least 1 lead placed at L2 or L3. Pain relief was measured utilizing relative percent pain improvement as self-reported by each patient before and after surgery. There were no differences between cervical and lumbar groups with regard to outcome measures. Purins A, Mundy L, Merlin T, Hiller J. Spinal cord stimulation for cardiac syndrome X. Diabetes Care. In addition, the number of subjects who did not have paresthesia was very small, and this end-point was not adequately powered to detect the difference in pain relief for subjects who reported feeling versus not feeling paresthesia. Moreover, these researchers stated that further studies with longer follow-up are needed to improve the patient selection, clarify the best timing to perform SCS in these patients, and better understand the potential loss of effectiveness of SCS over time. New York Heart Association Functional Class III or IV angina pectoris, reversible ischemia documented at least by a symptom-limited treadmill exercise test, and. SPRINT Physician Reference Guide.
