Other published head to head assessments involving these vendors or their closest peers.
Candid Health's record has not yet been reviewed on this site, so its side of this page rests on the build record. Its touchless rate, above 95 percent, is its own figure without a baseline, and it describes its engine plainly as reverse engineered payer rules with machine learning on the feedback loop.
Optimizing for claims that get paid is not the same as optimizing for claims that are correct, so ask both how they check the second. Waystar drafts appeals from payer specific templates; ask what review happens before they go out.
