Editorial Standards

Source hierarchy

We prefer primary public records: insurer disclosures, regulator data, statutes, regulations, and official guidance. Secondary sources can help locate or explain a primary source, but they do not replace it for a published rate, deadline, or appeal right.

Numbers keep their scope

A denial rate is published with its reporting year, line of business, denominator, and calculation method when those are available. We do not relabel a Medicare Advantage, Marketplace, state-plan, or contract-level rate as a national company-wide rate.

Historical overturn rates describe past aggregate reviews. They are not forecasts, success guarantees, or evidence that every denial should be overturned. Unlike reporting cohorts are separated instead of treated as a single league table.

Automation and AI

Automated tools may help extract, organize, and test public records. Publication rules and integrity checks are used to detect missing sources, duplicate entities, arithmetic errors, and scope drift. AI output is not treated as legal authority. Generated appeal letters are user-reviewed drafts grounded in the site’s sourced rules and data.

Corrections and updates

We update a page when a source changes, a new reporting year becomes available, or a material error is confirmed. A correction that changes a material figure or conclusion should be described on the public corrections page; minor grammar or formatting fixes may be made without a notice.
