From recent overturned decisions
“Nature of Statutory Criteria/Case Summary: A patient has requested reimbursement for a Zoll LifeVest. In this case, a review of the record reveals that the patient was newly diagnosed with systolic heart failure with a left ventricular ejection fraction LVEF of 30%. The patient was treated with guideline-directed medical therapy (GDMT) including carvedilol and spironolactone. A Zoll LifeVest was ordered …”
“Nature of Statutory Criteria/Case Summary: An enrollee has requested reimbursement for the wearable cardioverter defibrillator. Findings: Two of the three physician reviewers found the records document recent onset non-ischemic cardiomyopathy with an ejection fraction of 35%. There is some likelihood of recovery of left ventricular function in this instance over the initial three month period with evidence-based medical therapy. As …”
And one the reviewer upheld
“Nature of Statutory Criteria/Case Summary: An enrollee has requested reimbursement and prospective authorization and coverage for a wearable cardioverter defibrillator (Zoll LifeVest). Findings: Two of the three physician reviewers found that there is a lack of support for the device at issue in this clinical setting. There is potential for recovery of left ventricular function over time with medical therapy, …”
- 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 ABI Vest denials for Cardiac/Circ Problem overturned?
In 6 California IMR decisions from 2018 to 2025, reviewers overturned 2 (33.3%). In the last five years: 100.0% of 1. , 6 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.
