Credo Health vs Zus Health (2026)
Two answers to the problem underneath this whole category, that you cannot summarise a record you do not have. Zus is the broader platform: national networks, prescription fills, admission and discharge alerts, deduplicated and normalised across more than 320 million patients, with a published match rate that admits its own imperfection. Credo is the more determined retriever: three national networks rather than two, regional exchanges, and a manual path that chases records the networks do not return, with Care Map telling the user which records are still missing rather than presenting a partial history as a whole one. That honesty is the strongest thing on either record. If you want an infrastructure layer to build on, Zus. If you want the fullest possible history in front of a clinician before a specific visit, Credo, and ask how the manual retrieval cost is priced.
- It tells you what is missing. Care Map maps where a patient's records should exist and states plainly what has not been retrieved, rather than assembling whatever arrived and presenting the result as a complete history.
- The retrieval footprint is the deepest here and it does not stop at two networks: Carequality, CommonWell and eHealth Exchange are all named, alongside regional exchanges, and a manual path chases what the networks do not return.
- The product is pointed at the moment it matters, delivering a concise history, pre encounter risk analysis and quality gap closure before the visit rather than during it.
- Coverage and scale that no retrieval specialist matches: data from thousands of provider sites, prescription fills through Surescripts, admission and discharge alerts through named partners, across more than 320 million patients, all normalised to a common standard.
- It publishes the number that describes its own limits, a roughly 90 percent match rate, and links every summarised point to the underlying record, so provenance and imperfection are both visible.
- It is a platform other products build on, with distinct access routes for care teams, developers and analytics, rather than a single workflow.

Side by Side
Each record in one paragraph
Written to be quoted whole. Each paragraph states what the AI Health Index verified about the vendor, with the caveats attached. Generated from this pair’s live capability grades, so it moves when a grade moves.
The AI Health Index awards Credo Health its top capability grade on EHR and Interoperability Depth. Set against Zus Health, Credo Health grades higher on AI Centrality. Grades reflect evidence the AI Health Index could verify at the last review, so a low grade records disclosure the vendor has not published rather than a capability it has been shown to lack.

Questions buyers ask
Should we choose Credo Health or Zus Health?
On the axes where the AI Health Index separates them, Credo Health grades higher on AI Centrality, and Zus Health grades higher on Model Supply Chain Disclosure, AI Safety and PHI Stewardship and FDA and Regulatory Status. Zus Health leads on the greater share of scored axes, but the split means the decision turns on which constraint is binding rather than on an overall winner.
Where do Credo Health and Zus Health differ most?
The widest separation the AI Health Index records between Credo Health and Zus Health is on AI Centrality, where Credo Health grades B and Zus Health grades C. That axis sits in the AI Capability group, so it should carry the most weight for a buyer whose binding constraint is how much of the work the model itself is trusted to do.
Where do Credo Health and Zus Health grade the same?
The AI Health Index grades Credo Health and Zus Health the same on several axes, including Autonomy and Oversight Model, Model and Technology Transparency and Clinical and Operational Evidence. Neither holds an advantage the index can evidence on those axes, so they should not carry weight in a selection between these two.

Neither vendor publishes a security attestation or trust centre, which is a significant gap for two products whose entire function is aggregating records from other organisations. Neither publishes pricing or a pricing mechanism, and the commercial shapes differ in a way worth probing: Credo carries a variable operational cost for every record chased manually, and Zus prices a platform whose value scales with patient volume and consumption.
Credo's commercial pitch includes helping value based care organisations risk adjust more completely, which is a documentation incentive worth naming: retrieval that surfaces more diagnoses is also retrieval that raises reimbursement, and both effects come from the same feature.
