What this number is, and is not. It is the outcome of decisions in which the authority was named — not the effect of naming it. Reviewers cite the standard they applied, so the citation and the outcome share a cause. Read it as “disputes where this standard was the yardstick came out this way”, never as “citing this standard produces this result”.

These count only denials appealed all the way to independent review. Fewer than 1% of denials are appealed internally at all, so a share here is not the share of denials that are wrong — it is the share of contested ones reviewers did not sustain. California only, and only plans the state regulates: not self-funded employer plans, Medicare or Medicaid.
