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: A enrollee has requested reimbursement for the lab tests (CPT code 83520 and 8352059). Monoclonal gammopathy is a potential reversible cause for neuropathy. The appropriate testing by serum protein electrophoresis is considered within the standard of care when evaluating a patient for neuropathy without apparent etiology. A medical literature reviewed the standard battery of tests …”
“Nature of Statutory Criteria/Case Summary: The parent of an enrollee has requested authorization and coverage for autonomic nerve testing. Findings: Two of the three physician reviewers found this patient has been diagnosed with a mitochondrial cytopathy, and he has multiple symptoms suggestive of dysfunction of his autonomic nervous system. He has chronic constipation, excessive sweating, and wide fluctuations of pulse …”
“Nature of Statutory Criteria/Case Summary: An enrollee has requested reimbursement for blood test for evaluation of the enrollee’s autoimmune disorder. Findings: The physician reviewers found there is sufficient support in the peer reviewed literature for the immune function tests. The patient’s provider needs the clearest possible picture of what the patient’s immune parameters are in order to formulate the best …”
And one the reviewer upheld
“The physician reviewer found that Nature of Statutory Criteria/Case Summary: The patient has requested authorization and coverage for a 24-hour gadolinium urine test. A review of the literature reveals a lack of support for the requested 24-hour gadolinium urine test requested by this patient. The requested interpretation of 24-hour urine tests for gadolinium and how it correlates with disease or …”
- 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 Lab Work denials for CNS/ Neuromusc Dis overturned?
In 22 California IMR decisions from 2008 to 2023, reviewers overturned 7 (31.8%). In the last five years: 0.0% of 2. 6 were medical-necessity disputes, 16 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.
