Keyword matches on the reviewer’s findings, not causes. A tag that appears mostly in overturned decisions is worth documenting in an appeal; it is not a guarantee.
From recent overturned decisions
“The physician reviewer found that Nature of Statutory Criteria/Case Summary: A patient has requested authorization and coverage for the Intracept procedure. In this case, the patient's magnetic resonance imaging (MRI) scan showed minor disc bulges at L4-5 and L5-S1 without significant neural compression or advanced facet arthritis. The report also noted the presence of Modic changes and endplate irregularities. Further, …”
“The physician reviewer found that Nature of Statutory Criteria/Case Summary: A patient has requested authorization and coverage for the Intracept procedure. Intracept is a U.S. Food and Drug Administration (FDA)-approved minimally invasive outpatient procedure. It is implant-free and preserves spinal integrity by negating the need for extensive tissue exposure and disruption. No restrictions are placed on the patient afterward, and …”
“Nature of Statutory Criteria/Case Summary: A patient has requested authorization and coverage for radiofrequency ablation of the sacroiliac joint, with imaging guidance. Given the literature findings in support of RFA for sacroiliac pain, the documentation of subjective and objective findings consistent with sacroiliac-mediated pain, and the patient’s positive sacroiliac block with pain alleviation, the requested procedure is medically appropriate in …”
And one the reviewer upheld
“Nature of Statutory Criteria/Case Summary: A patient has requested authorization and coverage for radiofrequency ablation of the sacroiliac joint. Findings: The physician reviewer found that With regards to the evidence surrounding radiofrequency ablation of the sacrum, the evidence is mixed. The majority of studies evaluating sacral lateral branch radiofrequency ablation (SLBRFA) utilize single or dual intra-articular blocks for the diagnosis …”
- California only: these are decisions by independent reviewers under California's IMR program (plans regulated by the Department of Managed Health Care). Other states and self-funded employer plans use different reviewers and rules.
- Selection: only denials that a member took all the way to IMR appear. Most denials are never appealed, and the ones that reach an external reviewer are not a random sample.
- Overturned means the reviewer disagreed with the plan; it does not mean the treatment worked or that a similar request will be approved.
- Argument tags are keyword matches on the reviewer's findings. They describe what the findings mention, not why the case was decided.
- Categories are DMHC's own labels (treatment sub-category and diagnosis category); 'Other' is a catch-all and is excluded from rankings.

Questions
How often were Radiofreq Ablat denials for Orth/Musculoskeletal overturned?
In 161 California IMR decisions from 2002 to 2025, reviewers overturned 68 (42.2%). In the last five years: 51.4% of 70. 40 were medical-necessity disputes, 121 experimental/investigational.
What should an appeal document, based on these findings?
Whatever the plan's criteria ask for, shown in the record: the treatments already tried and their results, contraindications to the plan's preferred option, the guideline or evidence that supports the request, and the treating clinician's reasoning written to the criteria. The tag table shows which of these the reviewers mentioned most in overturned cases.
Does a California IMR result apply to my plan?
Only California plans regulated by the Department of Managed Health Care go to IMR. Other states and self-funded employer plans use different reviewers, but they weigh the same things.
Independent reviewers reverse plans when the record answers the criteria. Upload the denial letter; a senior reviewer reads it within 24 hours and tells you in writing whether it can be appealed and how. $0 upfront, 10% of what is recovered, nothing if we do not recover. Not a law firm.
