What the findings mention
From recent overturned decisions
“The physician reviewer found that Nature of Statutory Criteria/Case Summary: The patient has requested reimbursement for inpatient hospital admission services. The records indicate that prior to discharge, the patient’s antibiotic susceptibilities of the patient’s Escherichia coli (E. coli) were unknown. Additionally, the patient reportedly failed an oral antibiotic regimen with Bactrim prior to admission. The patient required treatment with intravenous …”
“Nature of Statutory Criteria/Case Summary: The patient has requested reimbursement for continued inpatient admission. The records indicate that the inpatient admission was medically necessary for the treatment of this patient’s medical condition. The provider noted that the patient’s condition included an underlying gallbladder abscess, which led to septic shock, atrial fibrillation, which was likely triggered by infection, and physical deconditioning …”
“The physician reviewer found that The patient’s parent has requested reimbursement for full hospital admission from 12/14/22 to 12/16/22. Infections with respiratory syncytial virus are particularly concerning in pediatric patients, as they often induce asthma-like reactions that can be life-threatening.

- 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 Admission denials for Infectious Disease overturned?
In 9 California IMR decisions from 2014 to 2024, reviewers overturned 4 (44.4%). In the last five years: 66.7% of 6. 9 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.
