Coverage decisions are subject to all terms and conditions of the applicable benefit plan, including specific exclusions and limitations, and to applicable state and federal law. Some benefit plans administered by the organization may not utilize Medical Affairs medical policy in all their coverage determinations. Contact customer services as listed on the member card for specific plan, benefit, and network status information. Medical policies are based on constantly changing medical science and are reviewed annually and subject to change. The organization uses tools developed by third parties, such as the evidence-based clinical guidelines developed by MCG to assist in administering health benefits. This medical policy and MCG guidelines are intended to be used in conjunction with the independent professional medical judgment of a qualified health care provider.

Related Medical Policies: Back Pain: Epidural Injections Back and Nerve Pain: Radiofrequency Ablation, Facet Joint, and other Injections Non-covered Services and Procedures These services are covered subject to medical necessity review. If a limit is not specified in the member health plan, the maximum follows the medical necessity guidelines in this policy. Description: Sacroiliac (SI) joint injection is an injection of local anesthetic and / or a steroid into the articular space between the spinal column and pelvis. Although evidence is limited due to the low number of randomized controlled clinical trials, inconsistencies between trials, and flaws in design and conduct of studies documenting the effectiveness of sacroiliac joint injections for the management of low back pain, these injections have become widely used. There is insufficient evidence of the efficacy, superiority over conservative treatments, or long-term outcomes of sacroiliac ablation or fusion procedures in the treatment of SI Joint related back pain. Coccydynia/ coccodynia--pain in the coccyx (tailbone) is most commonly the result of falling backwards and landing in a sitting position. While most cases resolve without medical care or with conservative management, a minority of individuals may develop chronic coccyx pain. Page 1 of 6

2 Indications of Coverage: A. Sacroiliac joint injections are considered medically necessary when ALL of the following conditions (1 through 5) are met: 1. Chronic back and buttock pain symptoms for at least three (3) months. 2. Physical exam findings consistent with sacroiliac joint (SIJ) symptoms. (e.g. thigh thrust test, distraction test, compression test, Flexion, Abduction, and External Rotation test (FABER) also known as Patrick s test, and/or Gaenslen s Maneuver indicate sacroiliac joint cause). The nerve root tension test (straight leg raise), if performed, must be negative unless the provider documents coexistence of both radicular and non-radicular pain. If bilateral injections are requested, the symptoms and physical exam findings, must be bilateral. 3. Within the last six months, the individual has completed a 6-week trial of medications such as anti-inflammatories, muscle relaxants, analgesic, opioids, gabapentin, and pregabalin. 4. Within the last six months, the individual has completed a 6-week trial of physical therapy (PT) or chiropractic manipulations (performed after the current episode of symptoms started and directed toward the sacroiliac joint symptoms/dysfunction). Note: Documentation of therapy administered by a Certified Athletic Trainer or regular participation in a program such as the Arthritis Foundation Exercise Program may also meet medical criteria for therapy. Note: If the symptoms are severe (requiring urgent medical care), the trial of conservative treatments (number 3 and/or 4) may not be required. 5. Documentation of an average pain level of 6 or greater on a scale of 0 to 10; or intermittent or continuous pain that is causing a functional disability. If the above Indications of Coverage (section A, 1 through 5) are met, an initial sacroiliac joint injection will be allowed. If the individual has experienced at least a 50% decrease in pain symptoms for at least one (1) week following the initial sacroiliac joint injection (and the member health plan allows), a second injection may be approved. The second sacroiliac joint injection must be given at least one (1) week after the previous injection and documentation must show there has been return of pain at level of 6 or greater on a scale of 0 to 10 or a return of functional disability related to the sacroiliac joint.

3 If a limit is not specified in the member health plan, a maximum of four (4) sacroiliac joint injections in a year (including intra-articular steroid injections, and periarticular injections), regardless of location (left or right), whether diagnostic or therapeutic, will be considered medically necessary when criteria are met for each injection. Note that bilateral injections will count as 2 injections. If a year is not described in the member health plan (e.g. per calendar year), a year is defined as the 12-month period starting from the date of service of the first approved injection. B. Coccyx injections are considered medically necessary when ALL of the following conditions (1 through 5 below) are met: 1. Chronic coccyx (tailbone) pain for at least three (3) months. 2. Physical exam findings show focal external palpation of the coccyx reproduces symptoms locally without pain, erythema, or swelling in the surrounding area. 3. Within the last six months, the individual has completed a 6-week trial of medications such as anti-inflammatories, muscle relaxants, analgesic, opioids, gabapentin, and pregabalin. 4. Within the last six months, the individual has completed a 6-week trial of physical therapy (PT) or chiropractic manipulations (performed after the current episode of symptoms started and directed toward the coccygeal joint symptoms/dysfunction). Note: Documentation of therapy administered by a Certified Athletic Trainer or regular participation in a program such as the Arthritis Foundation Exercise Program may also meet medical criteria for therapy. 5. Within the last six months, the individual has completed a 6-week trial of a donut or wedge cushion. Note: If the symptoms are severe (requiring urgent medical care), the trial of conservative treatments (numbers 3, 4, and/or 5 above) may not be required. If the above Indications of Coverage (section B, 1through 5) are met, an initial coccyx injection will be allowed. If the individual has experienced a decrease in pain symptoms of at least 50% for at least one (1) week following the initial coccyx injection (and the member health plan allows), a second injection may be approved. The second coccyx injection must be given at least one (1) month after the previous injection and Page 3 of 6

4 documentation must show there has been return of pain or functional disability related to the coccyx. If a limit is not specified in the member health plan, a maximum of two (2) coccyx injections in a year is considered medically necessary when criteria are met for each injection. If a year is not described in the member health plan (e.g. per calendar year), a year is defined as the 12-month period starting from the date of service of the first approved injection. C. Sacroiliac joint fusion (arthrodesis) procedures are considered medically necessary for the following: 1. As an adjunct to sacrectomy procedures related to tumors involving the sacrum or 2. As an adjunct to surgical treatment of sacroiliac joint infections or 3. For treatment of severe trauma (e.g. pelvic ring fracture) or 4. During surgical procedures such as correction of scoliosis extending to the ileum Limitations of Coverage: A. Review health plan and endorsements for exclusions and prior authorization or benefit requirements. B. If requested/used for a condition or diagnosis other than is listed in the Indications of Coverage, it will be denied as experimental, investigational, and unproven to affect health outcomes. C. If requested/used for a condition or diagnosis that is listed in the Indications of Coverage; but the criteria are not met, it will be denied as not medically necessary. D. If the previous sacroiliac joint injection or coccyx injection was not effective (did not reduce pain by at least 50%), a subsequent injection will be denied as not medically necessary. E. A second coccyx injection provided less than one (1) month after the initial injection will be denied as not medically necessary. Page 4 of 6

5 F. Ultrasound treatment, short wave diathermy, and transcutaneous nerve stimulation for treatment of coccydynia are considered experimental, investigational, and unproven to affect health outcomes and will be denied. G. More than four (4) sacroiliac joint injections (including intra-articular steroid injections, lateral sacral and periarticular injections), regardless of location (left or right,) whether diagnostic or therapeutic, in one year will be denied as not medically necessary. Note that bilateral injections count as 2 injections. H. Sacroiliac joint injections provided without the use of fluoroscopic or computed tomography (CT) guidance are not current standard medical practice and will be denied as not medically necessary. I. Performing a sacroiliac joint arthrogram in conjunction with a sacroiliac joint injection is considered integral to the procedure and not reimbursed separately. J. Nerve blocks (e.g. lumbar and sacral medial branch blocks and/or lateral branch blocks or lumbar L5 dorsal ramus block) for diagnosis or treatment of sacroiliac (SI) joint pain or pain resulting from SI joint derangement or dysfunction are considered experimental, investigational, and unproven to affect health outcomes and will be denied. K. Sacroiliac joint ablation (includes water cooled, pulsed, and thermal ablation), sacral branch neuroablations (e.g. lateral sacral branch neuroablation and lumbar L5 dorsal ramus ablation) or fusion/ arthrodesis are considered experimental or investigational for management of back/buttocks pain or SI joint dysfunction and will be denied. Diagnostic sacroiliac joint injections done in preparation for SI joint ablation or fusion/ arthrodesis for management of back/buttocks pain or SI joint dysfunction are not covered as they would be related to the non-covered ablation/ fusion service. L. Injection of a caustic agent such as phenol or alcohol into a sacroiliac joint is considered experimental, investigational, and unproven to affect health outcomes and will be denied. M. Percutaneous sacroplasty is considered experimental, investigational, and unproven to affect health outcomes and will be denied. N. Sacroiliac (SI) joint fusion/ minimally invasive SI joint fusion (e.g. ifuse implant) for sacroiliac joint dysfunction is considered experimental, investigational, and unproven to affect health outcomes and will be denied. O. If more than one type of pain treatment is requested/ performed on the same day, only one (1) type will be considered medically necessary at the discretion of the health plan. The other will be denied as not medically necessary. Page 5 of 6
