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 reimbursement for bilateral breast magnetic resonance imaging (MRI) with and without contrast. Per the medical records, the patient has silicone breast implants. Given that MRI may evaluate for silicone implant rupture, bilateral breast MRI with and without contrast was medically necessary for the evaluation of this …”
“The physician reviewer found that an enrollee has requested authorization and coverage for advanced imaging with contrast. Documentation notes a small renal finding. A review of current medical literature indicates that advanced imaging with contrast is an appropriate diagnostic modality in this clinical setting. As such, the requested imaging study is medically necessary for the evaluation of this enrollee.”
“The physician reviewer found that Nature of Statutory Criteria/Case Summary: A patient has requested authorization and coverage for magnetic resonance imaging (MRI) of the pelvis. Pelvic ultrasound is then the first line diagnostic imaging for pelvic pain or abnormality on exam. After a pelvic ultrasound has been performed, MRI of the pelvis is helpful to evaluate for rectovaginal endometriosis, deeply …”
And one the reviewer upheld
“The physician reviewer found that a patient has requested authorization and coverage for bilateral breast magnetic resonance imaging (MRI). According to the American College of Radiology (ACR) appropriateness criteria for the evaluation of a palpable mass in a patient greater than 40 years of age, a diagnostic mammography is the first step, followed by sonography. Rarely, if there is a …”
- 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 MRI denials for GU/ Kidney Disorder overturned?
In 42 California IMR decisions from 2010 to 2025, reviewers overturned 18 (42.9%). In the last five years: 43.3% of 30. 27 were medical-necessity disputes, 15 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.
