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: The patient has requested authorization and coverage for home health physical therapy services (three one-hour sessions weekly). In a systematic review to understand the benefits and harms of physical activity in people who may require a wheelchair with a focus on people with multiple sclerosis (MS), cerebral palsy (CP), and …”
“The physician reviewer found that Nature of Statutory Criteria/Case Summary: The patient has requested authorization and coverage for physical therapy and/or occupational therapy. The medical literature supports the use of physical and occupational therapy in patients with Parkinson's disease to maximize their function and mobility and minimize the need for caregiver assistance. In this case, the patient has impaired mobility …”

- 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 Physical Therapy denials for CNS/ Neuromusc Dis overturned?
In 47 California IMR decisions from 2002 to 2025, reviewers overturned 20 (42.6%). In the last five years: 44.4% of 9. 42 were medical-necessity disputes, 5 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.
