Should you build or buy Primary Source Verification (PSV) / Sanctions Monitoring?
Primary Source Verification (PSV) and Sanctions Monitoring software connects to authoritative data sources — state licensing boards across all 50 states, the OIG and SAM exclusion lists, the NPDB, and DEA registration records — to confirm that healthcare providers hold valid credentials and are not excluded from federal programs. It runs both initial verification at onboarding and continuous background monitoring to catch expirations, sanctions, or exclusions between credentialing cycles.
The build-vs-buy decision for Primary Source Verification and Sanctions Monitoring turns on whether the value lies in the data access network itself or in the workflow layer built on top of it; organizations that understand this distinction almost always reach the same conclusion about where the economics favor building versus buying.
Build it, buy it, or bridge?
When building makes sense
The honest case for building is narrow. What's genuinely buildable is the workflow layer on top of PSV data: the provider record structure, the verification queue, the alert routing when a license expires or an exclusion appears. Some organizations have built those workflow pieces using PSV data feeds from vendors as an API source, which is a legitimate hybrid approach. AI adds real value in document extraction from scanned credentials and automated follow-up for missing documentation, and those augmentations are buildable on lightweight tooling. The core data access layer, though, is not a build target for most organizations. Connecting to all 50 state licensing boards, maintaining those connections as board APIs change, and keeping sanctions list logic current with OIG and SAM updates is ongoing infrastructure work that vendors like Verisys and ProviderTrust have absorbed over years. An internal team would be building a smaller and less complete version of that network.
When buying makes sense
Buying makes sense because the product is the data network, not the software. Vendors have spent years building and validating connections to primary sources that a single health system or payer would spend more than three years of licensing fees to replicate — and still end up with incomplete coverage. Per-provider monitoring fees are modest relative to the compliance risk of a missed exclusion: a single provider billing under an active OIG exclusion can trigger substantial CMS recoupment actions. The verification audit trail that platforms like Verisys and ProviderTrust produce also carries direct value for NCQA and CMS audits. When the alternative to buying isn't actually building a full primary-source network but rather maintaining a smaller and patchier version of what already exists, the calculation is straightforward.
The desk read
The core value in PSV is access to primary source data feeds: state licensing boards across all 50 states, OIG and SAM exclusion lists, NPDB, DEA registration. Vendors like Verisys, CAQH, and ProviderTrust have spent years building and maintaining those integrations. A single health system or payer could technically build connections to some of those sources, but replicating the full primary-source network for internal use would cost more over three years than licensing access. The network is the product.
There's no build case for the data access layer. What's buildable is the workflow on top of it: the provider record, the verification queue, the ongoing monitoring alerts. Some organizations have built those workflow pieces using PSV data feeds from vendors as an API source. AI adds value in document extraction from scanned credentials and automated follow-up, but the PSV function itself is pure data infrastructure. Buying earns its keep here because the alternative isn't really building, it's maintaining a smaller and less complete version of what already exists.
Frequently asked
What is Primary Source Verification (PSV) / Sanctions Monitoring?
Primary Source Verification and Sanctions Monitoring software connects to authoritative data sources — state licensing boards across all 50 states, OIG and SAM exclusion lists, the NPDB, and DEA registration records — to confirm that healthcare providers hold valid credentials and are not excluded from federal programs. It runs both initial verification at onboarding and continuous background monitoring to catch expirations, sanctions, or exclusions between credentialing cycles.
When does building Primary Source Verification / Sanctions Monitoring make sense?
Building the workflow layer — provider records, verification queues, alert routing — on top of licensed PSV data feeds is viable for organizations that want proprietary integrations. Building the primary-source data network itself is not a realistic option for most organizations; the cost of connecting and maintaining 50+ state board feeds exceeds three years of vendor licensing fees.
When does buying Primary Source Verification / Sanctions Monitoring make sense?
Buying makes sense for virtually all healthcare organizations because the product is the data access network, not the software layer. Vendor-maintained connections to state boards, OIG, SAM, NPDB, and DEA are expensive to replicate, and the per-provider monitoring fees are modest relative to the compliance risk of a missed exclusion or expired license.
What are the main Primary Source Verification / Sanctions Monitoring vendors?
Representative vendors include Verisys, ProviderTrust, Verifiable, Assured. B4 Pro scores the full set.
What is continuous monitoring in provider credentialing, and why does it matter?
Continuous monitoring checks provider credentials and exclusion status on an ongoing basis between formal re-credentialing cycles, which typically happen every two to three years. It matters because licenses can lapse, malpractice actions can be filed, and OIG exclusions can be issued at any time. Catching a problem within days instead of months limits the organization's liability exposure significantly.
