A denial is three jobs, and buying one tool for all three is how the dollars sit there. Prevention stops a claim before it goes out, rework fixes the one that came back, and an appeal is the filing after rework fails. Black Book, 8 June 2026 says 74% of qualified respondents prioritized denial prevention over post-denial recovery, and 78% ranked payer friction as a top-three technology stressor. Those two numbers explain the incentive to buy a prevention module and still have a pile of claims that already denied.
The matrix uses the same eight weights as the claim-status matrix: channel coverage 20, autonomy and touch rate 15, evidence per action 15, outcomes with a denominator 15, integration and time to first claim 10, pricing unit 10, buyer segment 10, agent security 5. Status follow-up links to Best claim status and A/R follow-up automation vendors (2026). Appeals link to Best AI Appeals Software (2026) and are not rescored here.
What resolves the claim
CARC and RARC families map to an action: a corrected claim, a reconsideration, an appeal, or a write-off. A low-dollar write-off is its own line, because the cost of working the claim can pass the dollars left on it. Software and services are different purchases. AGS Health and Ensemble are services ranks. A cell with no independent source stays not published.

When to pick someone else
Pick a services rank when you want labor under a contract, and pick a software rank when you want a system your staff still operates. Pick AKASA when the Black Book category you need is denial prevention and denial analytics, not when you need a published claim-status rate, because that rate is not published. Pick Waystar's appeal-letter note from KLAS when denials satisfaction is the question, and do not read it as a recovery percentage. Pick someone else on Experian and FinThrive when the KLAS report says denial prevention was the module customers waited years for.
Seven questions to ask in the demo
- Show a pended claim, a denial, and an appeal as three different actions.
- Which CARC families become a corrected claim, a reconsideration, an appeal, or a write-off?
- What is the write-off threshold, and who sets it?
- What is the touch rate on rework, and what is the denominator?
- Is this a software login or a services team, and which contract is the one you sign?
- What evidence is stored on the action, and can the appeal use it later?
- What did KLAS or Black Book actually rank you for, in one category name?
RFP checklist
- Three workflows separated: status follow-up, rework, appeal.
- CARC/RARC map to corrected claim, reconsideration, appeal, or write-off.
- Low-dollar write-off rule, with the dollar line written down.
- Software or services, named in the order form.
- Touch rate and recovery, each with a denominator, or marked not published.
- The category rank you are allowed to cite, and the category you are not.
Same limit as the Black Book release: fewer vendors is not a reason to carry a weak denial module. Hospitals that want a shorter vendor list still cannot.
