Orthopedic procedures denials at external review
When a California health plan denied care in the orthopedic procedures class and the enrollee took it to Independent Medical Review, this is what independent physician reviewers decided.

What stands out here
computed from this classamong the lowest
At 30.5%, this is the 3rd-lowest overturn rate of the 22 treatment classes carrying one — one of the few where reviewers more often agreed with the plan than not.
most-cited standard
Reviewers named FDA more than any other standard here — 36 decisions, which came out at 16.7%, 14 points below the class as a whole. Citing a standard and the outcome share a cause; this is not the effect of naming it.

What reviewers relied on
3 validated codesCalifornia requires each published decision to carry “a detailed case summary that includes the specific standards, criteria, and medical and scientific evidence, if any, that led to the case decision” (Health & Safety Code § 1374.33(h)(1)(K)). These are the elements our extraction found in this class, split by how the decision came out.
| What the reviewer relied on | In overturns | In upholds |
|---|---|---|
| the FDA label or approval status | 5%n=115 | 12%n=262 |
| a standardised level-of-care instrument | 0%n=115 | 0%n=262 |
| a California statutory definition | 2%n=115 | 0%n=262 |
Read as description, not instruction. These are patterns in what reviewers wrote, not steps to follow, and no combination of them predicts an outcome. Only codes that cleared the validation gate appear — thirteen did not.

Medical-necessity review asks whether the care is needed. Experimental/investigational review asks whether it is likely to be more beneficial than standard therapy — a harder statutory test, and the rates show it.
Every figure on this page is conditional on a denial having reached external review. Fewer than 1% of denials are appealed internally at all, so this describes denials that were fought to the end — not denials in general — and it describes California only. Who this does not cover.
