CertifyOS vs Medallion (2026)
Both are NCQA certified verification organizations, and they sell the certification differently. CertifyOS sells a provider data platform that plans and health systems configure and run, with verification, monitoring and roster management on top and one provider record delivered by API. Medallion runs the operation for its customers: credentialing, payer enrollment, rosters, delegated credentialing, privileging and licensing, with agents and people splitting the work on published lines. The decision is platform or service. CertifyOS suits a team that wants to own the process. Medallion suits one that wants it done.
- A platform the customer runs, with more than 600 primary sources and one provider record delivered by API, webhooks and bulk export.
- Continuous monitoring of licenses, sanctions and exclusions across the whole network.
- Strong adoption among health plans, with eight of the ten publicly listed US plans reported as clients.
- The work done as a service across the provider lifecycle, from credentialing to enrollment, rosters and licensing.
- It publishes which tasks its agents do and what sends a case to a person.
- Contractual service levels on turnaround and accuracy, with SOC 2 Type II named on its own pages.

Questions buyers ask
How do CertifyOS and Medallion work with the EHR?
For CertifyOS, the company describes versioned REST endpoints, including one that pulls a provider's CAQH ProView data and one that returns a signed link to the provider's primary source verification file, and a webhooks endpoint that pushes events such as credentialing completed and provider terminated into customer systems. Its CAQH guide describes automatic rostering into CAQH, so CAQH is a named system read from and written to.
With Medallion, the company integrates directly with primary sources for verification and ongoing monitoring, including the state medical boards' federation, the national practitioner data bank, federal exclusion and entity databases and the national provider registry, and it auto fills provider profiles from the registry, CAQH and uploaded documents. From the AI Health Index, drawn from each vendor's own published materials and the regulatory record, verified September 23, 2026. No vendor pays for placement.
How are CertifyOS and Medallion priced and sold?
In CertifyOS's case, the company sells a platform with configurable products on top (credentialing, licensing, monitoring, roster management and SharedCred) through a demo, and quantifies return in percentages, 75 percent lower re-credentialing costs on the home page, with no rates. Nor is a unit of charge stated, whether per credentialing event, per provider under monitoring, per API call or a platform subscription.
For Medallion, the page's reference to performance commitments connects to what the why page publishes: outcomes backed by contractual performance with defined service levels, guaranteed turnaround times and a 99.9 percent accuracy figure. Whether any fee is at risk when those levels are missed, or whether the commitment is a service level with credits, is not stated, and that decides what the guarantee is worth. From the AI Health Index, drawn from each vendor's own published materials and the regulatory record, verified September 23, 2026. No vendor pays for placement.
How do CertifyOS and Medallion handle patient data?
With CertifyOS, the company's security posts describe encryption, monitoring and documented policies, and its 2023 post frames its data as providers' personal information rather than patient data. Nothing says how long primary source verification files and supporting documents are kept, whether provider data is used to train or improve the matching and cleansing models, or whether anything is deidentified.
In Medallion's case, the scoping point first, because it is the company's own and it is accurate: what flows through a credentialing platform is provider and customer data. From the AI Health Index, drawn from each vendor's own published materials and the regulatory record, verified September 23, 2026. No vendor pays for placement.
Which settings and specialties do CertifyOS and Medallion cover?
For CertifyOS, specialty agnostic by design, with the company noting five core data entry points serve any provider type or specialty. Coverage is administrative rather than clinical, so it does not extend into care delivery.
With Medallion, the Andros acquisition, which the company says brings more than a million providers across nearly 400 organizations and health plans onto its platform, will extend the plan and health system side when those customers move. From the AI Health Index, drawn from each vendor's own published materials and the regulatory record, verified September 23, 2026. No vendor pays for placement.
