Sacroiliac Joint Fusion denials in California external review
In the California DMHC record, independent physician reviewers decided 36 published external-review cases involving Sacroiliac Joint Fusionand overturned the plan’s denial in 36.1%. That is a historical result among cases that reached this program, not a forecast for an individual appeal.

| Sacroiliac Joint Pain | 15 | 26.7% |
What the insurer actually argued
| Reason given | Decisions | Overturned |
|---|---|---|
Experimental/Investigational The plan called the treatment unproven. These turn on published evidence, so the appeal is a literature argument. | 27 | 37% |
Medical Necessity The plan said the care wasn’t medically necessary. The most common fight, and the most winnable. | 9 | 33.3% |
What the reviewers wrote
Where the denial was overturned
Nature of Statutory Criteria/Case Summary: An enrollee has requested authorization and coverage for bilateral sacroiliac (SI) joint fusion surgery. Polly and colleagues concluded that minimally invasive SI joint fusion using triangular titanium implants was more effective than nonsurgical management at one year in relieving pain, improving function, and improving quality of life in patients with SI joint dysfunction caused by degenerative sacroiliitis or SI joint disruptions. The International Society for Advancement of Spine Surgery (ISASS) policy statement for minimally invasive SI joint fusion provide specific indications for surgery (Lorio and Rashbaum).
Nature of Statutory Criteria/Case Summary: An enrollee has requested authorization and coverage for sacroiliac (SI) joint fusion surgery. In the peer-reviewed medical literature, researchers performed a Level 1 study on patients with SI joint dysfunction. The authors concluded that SI joint fusion using triangular titanium implants was more effective than nonsurgical management at one year in relieving pain, improving function, and improving quality of life. Applying the International Society for Advancement of Spine Surgery (ISASS) criteria, this patient meets the requirements for minimally invasive SI joint fusion.
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: An enrollee has requested authorization and coverage for sacroiliac joint fusion. In peer-reviewed medical literature, researchers provided evidence that minimally invasive SI joint fusion using triangular porous coated implants placed across the SI joint improved pain, disability and quality of life at 24 months in patients with SI joint dysfunction due to degenerative sacroiliitis and SI joint disruption, and was associated with a decrease in opioid usage for SI joint or low back pain.
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.
