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
“Nature of Statutory Criteria/Case Summary: An enrollee has requested reimbursement for the computed tomography (CT) perfusion with contrast. Findings: The physician reviewer found that the acute management of strokes has undergone a fundamental change in the last several years. Typically, a patient presents with stroke symptoms, and a decision must quickly be made regarding whether thrombolytic therapy is indicated. This …”
“Nature of Statutory Criteria/Case Summary: An enrollee has requested reimbursement for the coronary computed tomography (CT) scan for evaluation of the enrollee’s chest pain and lightheadedness. Findings: The physician reviewer found that based on the records provided this patient presented with ongoing atypical chest discomfort that has an exertional component, is reproduced on treadmill exercise and is associated with T-wave …”
“Nature of Statutory Criteria/Case Summary: An enrollee has requested reimbursement for dopamine transporter single-photon emission computed tomography (DaT SPECT) scan. Findings: Three physician reviewers found that while a DaT SPECT scan is not indicated for all patients with tremor, it has been shown to be useful when the diagnosis of Parkinson’s disease versus essential tremor is suspected. These diseases can …”
And one the reviewer upheld
“Nature of Statutory Criteria/Case Summary: The patient has requested authorization and coverage for computed tomography (CT) scan of the chest and CT scan of the abdomen. The available records state that this patient presents with a short history of night sweats and weight loss. The patient’s night sweats have a possible alternative diagnosis in menopause, which should be further considered …”
- 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 CT Scan denials for CNS/ Neuromusc Dis overturned?
In 25 California IMR decisions from 2003 to 2022, reviewers overturned 7 (28.0%). In the last five years: 0.0% of 2. 20 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.
