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 patient has requested authorization and coverage for treatment in an acute rehabilitation facility. This patient has a rehabilitation diagnosis of stroke. Her rehabilitation will most likely be complicated by her hip fracture. These two diagnoses require a higher level of rehabilitative care to help her progress in rehabilitation and decrease the likelihood of fall. …”
“The physician reviewer found that Nature of Statutory Criteria/Case Summary: The patient has requested reimbursement for inpatient rehabilitation services. The patient demonstrated multi-system limitations which required 24-hour monitored nursing care, daily medical oversight, and cautious physical and occupational therapies. The patient’s safety was at risk due to reduced sensation in the leg, poor overall strength, and greatly reduced vital capacity. …”
“Nature of Statutory Criteria/Case Summary: The patient has requested reimbursement and prospective authorization and coverage for acute rehabilitation hospitalization. In this case, prior to hospitalization, the patient was able to function with moderate assistance with an assistive device.

And one the reviewer upheld

Per the medical records, the patient’s diagnoses include lumbar spinal stenosis, cervical spinal stenosis with myelopathy with unsteady gait, gastroesophageal reflux disease (GERD), hereditary and idiopathic neuropathy, and urinary incontinence.

- 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 Inpt Admission denials for Orth/Musculoskeletal overturned?
In 66 California IMR decisions from 2003 to 2025, reviewers overturned 17 (25.8%). In the last five years: 15.8% of 19. 66 were medical-necessity disputes.
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.
