What the findings mention
From recent overturned decisions
“Nature of Statutory Criteria/Case Summary: A patient has requested authorization and coverage for the Euflexxa injection series. Viscosupplementation is reserved for patients with a history of lasting benefit from prior injections and in cases where the remaining options are limited. In this case, the patient has a history of arthritis with right knee pain and past symptom relief with Euflexxa …”
“The physician reviewer found that Nature of Statutory Criteria/Case Summary: A patient has requested authorization and coverage for Euflexxa administered to the left knee. As noted in the meta-analysis from Han and colleagues, hyaluronic acid is appropriate for the treatment of patients with knee osteoarthritis. As noted in a 2020 level 1 meta-analysis, viscosupplementation injection was the only treatment to …”
“The physician reviewer found that a patient has requested authorization and coverage for Synvisc-One injection to the left knee.Evidence from systematic reviews and randomized controlled trials indicates that although viscosupplementation may relieve knee pain in some patients with osteoarthritis, data have not established which patients will benefit.

- 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 Viscosupp Injection denials for Immuno Disorders overturned?
In 8 California IMR decisions from 2019 to 2025, reviewers overturned 7 (87.5%). In the last five years: 83.3% of 6. 7 were medical-necessity disputes, 1 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.
