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 reimbursement for magnetic resonance imaging of the left knee. The American College of Radiology (ACR) appropriateness criteria for the evaluation of chronic knee pain in adults with initial radiographs demonstrating degenerative changes note that magnetic resonance imaging may be appropriate as the next imaging examination. Per the medical records, given that …”
“The physician reviewer found that Nature of Statutory Criteria/Case Summary: A patient has requested authorization and coverage for magnetic resonance imaging scan of (1) the left knee and/or (2) lumbar spine. The American College of Radiology (ACR) appropriateness criteria for the evaluation of chronic knee pain recommend radiographs as the initial imaging study. Conservative management, including physical therapy for at …”
“The physician reviewer found that Nature of Statutory Criteria/Case Summary: A patient has requested authorization and coverage for compression garments and/or a second magnetic resonance imaging (MRI) of the bilateral hands. The patient reports symptoms of swelling, tendinitis, and pain. Compression garments will help with edema and swelling caused by a reaction to fluoroquinolones. Compression garments have been shown to …”
And one the reviewer upheld
“The physician reviewer found that a patient has requested authorization and coverage for magnetic resonance imaging (MRI) scan of the entire back. According to the American College of Radiology, the first appropriate imaging for the evaluation of low back pain with radicular symptoms is lumbar radiographs. If the pain persists after a trial of optimal medical management, and the patient …”
- 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 Orth/Musculoskeletal overturned?
In 527 California IMR decisions from 2001 to 2025, reviewers overturned 209 (39.7%). In the last five years: 51.7% of 172. 511 were medical-necessity disputes, 15 experimental/investigational, 1 urgent care.
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.
