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 a patient has requested a authorization and coverage for ablation of malignant prostate tissue transrectal High Intensity Focused Ultrasound (HIFU). HIFU is a U.S. Food and Drug Administration (FDA)-approved treatment for prostate cancer. According to the clinical practice guidelines and the patient’s clinical presentation of prostate cancer with multiple comorbidities, HIFU is an appropriate option …”
“Nature of Statutory Criteria/Case Summary: The patient has requested authorization and coverage for radiofrequency ablation. The survival of patients with metastatic breast cancer is incredibly variable. The National Comprehensive Cancer Network (NCCN) notes the clinical description of stage IV breast cancer as oligo-metastatic. Local, targeted resection of metastases in select patients is a standard therapeutic approach that may confer a …”
“Nature of Statutory Criteria/Case Summary: The patient requested authorization and coverage for a hepatectomy/surgical resection of the liver and open ablation of liver tumors with a one-day inpatient hospital stay for the combined liver and colorectal surgery.The record reflects that the patient has stage IV colorectal cancer with lung and liver metastases. The survival of stage IV colorectal cancer patients …”
And one the reviewer upheld
“The physician reviewer found that Nature of Statutory Criteria/Case Summary: A patient has requested authorization and coverage for high intensity focused ultrasound (HIFU) prostate ablation. This patient has high volume, intermediate risk, progressive prostate cancer. The American Urological Association (AUA) Guidelines on Clinically Localized Prostate Cancer report that, “With absence of randomization, non-standardized protocols, and insufficient follow-up, the role of …”
- 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 Cancer overturned?
In 25 California IMR decisions from 2002 to 2025, reviewers overturned 12 (48.0%). In the last five years: 80.0% of 5. 4 were medical-necessity disputes, 21 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.
