From recent overturned decisions
“The physician reviewer found that a patient has requested authorization and coverage for a Synvisc One injection for knee osteoarthritis. Per the medical records, the patient has osteoarthritis with chronic pain and has tried and failed conservative treatments, including medications and prior injections, without relief. Given the patient’s limited options and based on the current medical literature, a Synvisc One …”
“The physician reviewer found that a patient has requested authorization and coverage for Durolane injection administered to the affected knee. Per the medical records, the patient has osteoarthritis with chronic pain and has tried and failed conservative treatments, including medications and physical therapy, without relief. The patient has also experienced benefit from prior viscosupplementation in the other knee. The requested …”

- 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.

Does a California IMR result apply to my plan?

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.
