Read these numbers carefully
  • 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?

Denied for this?

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.
