Keyword matches on the reviewer’s findings, not causes. A tag that appears mostly in overturned decisions is worth documenting in an appeal; it is not a guarantee.

- 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.

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.
