Fusion denials in California external review
In the California DMHC record, independent physician reviewers decided 246 published external-review cases involving Fusionand overturned the plan’s denial in 28%. That is a historical result among cases that reached this program, not a forecast for an individual appeal.

What the insurer actually argued
| Reason given | Decisions | Overturned |
|---|---|---|
Medical Necessity The plan said the care wasn’t medically necessary. The most common fight, and the most winnable. | 197 | 26.4% |
Experimental/Investigational The plan called the treatment unproven. These turn on published evidence, so the appeal is a literature argument. | 47 | 34% |
What the reviewers wrote
Where the denial was overturned
Findings: The physician reviewer found that Nature of Statutory Criteria/Case Summary: The patient has requested authorization and coverage for L4-L5 minimally invasive intradiscal lumbar interbody fusion (MIS-IntraLIF) with L4-5 facetectomies and discectomy, intrafacet and interbody autograft-allograft arthrodesis, and placement of interbody mechanical device. Treatment of low back pain with lumbar fusion, in the absence of instability, trauma, tumor, or fracture is and has been a very common practice although controversy remains in terms of its efficacy, safety, and cost effectiveness. The main question explored in current medical literature is whether lumbar spinal fusion surgery is better than nonoperative management in patients who have already tried and failed long-term exhaustive conservative management.
Nature of Statutory Criteria/Case Summary: An enrollee has requested authorization and coverage for two level lumbar fusion, with or without cage. Treatment of low back pain with lumbar fusion, in the absence of instability, trauma, tumor, or fracture is and has been a very common practice but remains controversial in terms of its efficacy, safety, and cost effectiveness versus nonsurgical strategies. In a meta-analysis, Xu and colleagues concluded that spinal fusion was not better than nonoperative treatment for degenerative disc disease with regard to pain and disability and that careful evaluation of the risks of reoperation and the complications of lumbar fusion surgery were needed in such decisions. Yavin and colleagues suggest that lumbar fusion is most efficacious for patients with spondylolisthesis, a condition that this patient does not have.
Where the denial was upheld
Findings: The physician reviewer found that Nature of Statutory Criteria/Case Summary: The patient has requested authorization and coverage for posterior sacroiliac joint fusion procedure. Researchers explain, “The sacroiliac joint may be a primary source of pain in patients complaining of low back and/or buttock pain. Nonsurgical treatment of sacroiliac joint pain typically includes structured core and pelvic muscle flexibility and strengthening; pharmaceutical management through oral and injectable medication; and ablation procedures. For patients who do not improve with comprehensive, nonoperative treatment, surgical fusion of the sacroiliac joint is an option with overall good reported outcomes and high patient satisfaction. Minimally invasive surgery (MIS) approaches have been shown to have lower morbidity and earlier recovery than traditional open approaches.
Nature of Statutory Criteria/Case Summary: The patient has requested authorization and coverage for (1) L5-S1 anterior lumbar interbody fusion surgery and (2) L4-L5 fusion surgery. Medical literature state, “A trial of conservative therapy may be considered for patients with low-grade spondylolisthesis presenting with radiculopathy and/or pseudoclaudication. These options may include physical therapy, epidural steroid injection, and pain medications. If unresolved, surgical options may include decompression alone or decompression and fusion.” Researchers state, “Patients with symptomatic lumbar spondylolisthesis may first be treated with conservative management strategies including, but not limited to, non-narcotic and narcotic pain medications, epidural steroid injections, transforaminal injections, and physical therapy.
Figures and quotations on this page come from 42,749 published decisions in the California DMHC Independent Medical Review dataset. These are California external-review outcomes. Other state and federal programs have different eligibility rules, processes, and current availability; the rates here do not transfer to those programs or predict an individual result. Excerpts are quoted verbatim from the public record and describe this treatment generally, not any individual case.
These outcomes describe eligible cases completed through California DMHC’s Independent Medical Review program. They do not estimate the chance that an internal appeal, an external review in another jurisdiction, or your individual case will succeed. Use the record to identify evidence patterns involving Fusion, then check the rights and deadlines that apply to your plan.
