For appeal teams and platforms
The external-review record, licensed for use inside a product
42,621 published California Independent Medical Review decisions, classified by treatment, condition and the standards reviewers named, with a ranked treatment-class release and the test of whether that ranking holds. For appeal-drafting tools, navigation platforms and RCM software that need outcomes to cite. Every figure counts only denials that reached external review, and nothing is licensed until California’s Department of Managed Health Care approves commercial use in writing.
Does the ranking hold?
tested, not assertedA ranking of treatment classes by past outcome is a forecast, so it is scored out of sample on every release: fitted on 2021–2023, then measure what those classes actually did in 2024–2025.
0.84
rank correlation between the two windows
37.7 pts
separation between the top and bottom quartile, in the window it was never fitted on
8.9 pts
typical move for a single class — the honest error bar on any one row
Classes in the top quartile ran 85.7% against 47.9% for the bottom quartile, with no refitting. Only 29 of the 71 shipped classes clear n ≥ 30 in both windows, so the test runs on the larger ones — it is evidence the ranking is stable, not proof that every row is. The figure is recomputed on every release and published whatever it says.

what you receive- Rows
- 42,710 decisions, 2001 to 2025

- 11 that failed their accuracy check

- Where it came from
- Source, statute, citation and the date we captured it
What is not in it. No written decisions. The reviewers’ narratives stay in our build database and are sold to nobody at any price — they are tens of thousands of real medical histories, and a licensed file travels further than a web page. No health plan names either: California removes those before publishing.

$6,000/yr
indicative price
- Every published decision as a row-level table per release, with our validated categories, schema and checksum
- The ranked treatment-class release as a readable document and a CSV: every class with n and an interval, the characterisation gap, and the out-of-sample test of whether the ranking holds
- Commercial rights to use the table inside your product, granted only once California's Department of Managed Health Care has approved commercial use in writing
- A new release when the Department publishes a new file, stamped with the Department's own modification date
- Attribution terms and our neutrality commitment in writing, so your users can check them
California only, and every figure counts denials that reached external review. A file per release, not a live API. Nothing is licensed or invoiced until the Department approves commercial use in writing: its own portal says commercial uses must be approved, and a licence we are not yet entitled to grant would be worth nothing to you. Priced annually because the source does not change monthly.
NOT YET ON SALE · no payment taken
If you build an appeal-drafting product
Your letters have nothing solid to cite, and it is not for want of trying — the evidence has not existed in a usable form. It is also not something a drafting tool can publish about itself: a patient-side product quoting its own success rates reads as marketing, and the reviewer on the other side of the letter knows it.
At $6,000/yr the licence costs what about 150 appeal letters cost a patient at one drafting service’s $39.95 price. Nothing is licensed or invoiced until the Department approves commercial use in writing — its own portal says commercial uses must be approved, and a licence we are not yet entitled to grant would be worth nothing to you.
A neutral record is citable precisely because it is also sold to the plans. That is the seat this occupies, and the reason the same price applies to both sides.
Not on sale yet, and the reason is public. We have asked California’s Department of Managed Health Care for written permission to sell products built from its published records, and we will not take payment until it answers.
