Medical-necessity criteria Blue Cross NC generally applies
Lumbar Fusion - "Lumbar fusion with or without decompression is considered medically necessary to treat ANY of the following conditions:" Instability - "Degenerative spondylolisthesis with flexion and extension lateral spine x-rays showing a fixed anterolisthesis of greater than or equal to 3 mm, or movement of greater than or equal to 3 mm and symptoms or functional impairment have not responded to at least 6 weeks of conservative management. The medical record must document the surgeon's interpretation of office-based flexion-extension lateral spine x-rays to evaluate for the presence or absence of anterior-posterior lumbar instability. Verbal attestation will not be sufficient to meet the requirements." Also instability from tumor, infection, fracture or dislocation. Isthmic spondylolisthesis: "Congenital (Wiltse I) or acquired pars defect (Wiltse II) with flexion and extension lateral spine x-rays showing a fixed anterolisthesis of greater than or equal to 3 mm, or movement of greater than or equal to 3 mm; Failure of at least 3 months of conservative management; ANY of the following: Persistent back pain (with or without neurogenic symptoms) with functional impairment; Listhesis greater than 50% in children, 75% in mature adolescents or progressed by more than 30%; Progressive postural deformity or gait abnormality; Persistent functional impairment; Neurological symptoms." Recurrent same-level disc herniation: "At least 3 months have elapsed since the prior procedure; The patient experienced significant relief of symptoms following the procedure; Recurrent symptoms or functional impairment have not responded to at least 12 weeks of conservative management; Neural compression correlating with the clinical presentation and instability is demonstrated on imaging studies. Note: Fusion for same-level disc herniation without instability may be considered following two (2) prior discectomies at that level." Pseudoarthrosis: "Advanced imaging studies highly suggestive of nonunion ...; At least 6 months have elapsed since the prior procedure; The patient experienced significant relief of symptoms following the procedure; Recurrent symptoms or functional impairment have not responded to at least 12 weeks of conservative management following confirmation of the diagnosis." Spinal stenosis: "Lumbar fusion is considered medically necessary as an adjunct to decompression for treatment of spinal stenosis (central or foraminal) when ANY of the following (1-4) are present AND ALL additional criteria are met: Instability (anterolisthesis) is demonstrated on imaging studies, or anticipated due to EITHER of the following: Facet joint excision greater than 50% bilaterally or 75% unilaterally at the level fused; Resection of the pars interarticularis at the level fused; Indirect decompression is planned with an anterior approach and provided the procedure is not being done solely for degenerative disc disease (discogenic or axial low back pain); Adjacent-level stenosis ...; Recurrent stenosis ...; Additional criteria (ALL are required): Neurogenic claudication or radicular pain with significant functional impairment; Failure to respond to at least 6 weeks of conservative management; Documentation of central/lateral recess/or foraminal stenosis on MRI, CT, or CT myelography performed within the past 12 months." Also flat back syndrome, implant/instrumentation failure, lumbar synovial cyst, Scheuermann's kyphosis and scoliosis (see scoliosis row). [NEEDS CLINICAL SPOT-CHECK]

- {"text":"\"Indications other than those addressed in this guideline are considered not medically necessary including, but not limited to, the following: Isolated axial low back pain, with or without imaging findings of degenerative disc disease, annular tears, disc bulges, protrusion, extrusion, or sequestration; Chronic nonspecific low back pain; Facet joint syndrome; Degenerative lumbar spondylosis without stenosis or spondylolisthesis. Staged, multi-session spinal fusions are considered not medically necessary for fusion involving fewer than three (3) levels, unless performed for treatment of severe scoliosis or other spinal deformities.\"","source":"https://guidelines.carelonmedicalbenefitsmanagement.com/spine-surgery-2026-09-19/"}
