Credo Health vs Zus Health (2026)
Two answers to the problem underneath this whole category, that you cannot summarize a record you do not have. Zus is the broader platform: national networks, prescription fills, admission and discharge alerts, deduplicated and normalized across more than 320 million patients, with a published match rate that admits its own imperfection. Credo is the more determined retriever: four national exchange frameworks, regional exchanges, and a manual path that chases records the networks do not return, and it describes telling the user which records are still missing rather than presenting a partial history as a whole one. 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: its product material describes mapping where a patient's records should exist and stating plainly what has not been retrieved, rather than presenting whatever arrived as a complete history.
- The retrieval footprint does not stop at the networks: the eHealth Exchange, Carequality, CommonWell and TEFCA 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: data from thousands of provider sites, prescription fills through Surescripts, admission and discharge alerts through named partners, across more than 320 million patients, all normalized to a common standard.
- It publishes the number that describes its own limits, a roughly 90 percent match rate, and links every summarized 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.

Each vendor in one paragraph
Written to be quoted whole. Each paragraph opens the AI Health Index profile of the vendor: what the product is, who buys it and what it does.
Credo Health, based in Denver and led by founder and chief executive Carm Huntress, retrieves and assembles patient records for value based care. Its Acquire agent identifies where a patient has received care and pulls records through national exchange frameworks (the eHealth Exchange, Carequality, CommonWell and TEFCA) and regional exchanges, and where those networks return nothing, recovers records from source providers by telephone, secure portal and fax; its affiliates include Medical Records Exchange LLC, doing business as Chartfast.

Zus Health assembles a longitudinal patient record from national data networks and delivers it to care teams, analysts and developers. The Zus Aggregated Profile queries CommonWell and Carequality for medical history, adds pharmacy fill data, admission and discharge feeds and lab results, matches records to one person through a proprietary universal patient index, deduplicates and normalizes everything to FHIR, and shares a customer's contributed data back to the networks.

Neither vendor publishes a security attestation or trust center, which is a significant gap for two products whose entire function is aggregating records from other organizations. Zus publishes no pricing mechanism. Credo publishes its basis, a flat fee for each successful placement of data and a subscription for keeping records current, without figures, so every record chased manually still carries an operational cost to ask about.
Credo's commercial pitch includes helping value based care organizations 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.
