HealthVerity taXOnomy
The nation’s most comprehensive open and closed claims dataset
The full patient journey, without the gaps
The most complex therapies demand the most complete view of the patient journey. taXOnomy is now the industry’s most comprehensive open and closed claims dataset, integrating HealthVerity’s curated closed claims with the deepest open-claims coverage available, representing roughly 9 in 10 insured Americans for prescriptions and 7 in 10 for medical encounters. Linked by Universal HVID, updated monthly, and backed by one HIPAA certification, taXOnomy supports commercial analytics, market access, medical affairs and real-world evidence from a single asset.
No fragmentation, no stitching, no blind spots.
“taXonomy offers a comprehensive source of longitudinal claims data, with broad representation across payers in the US healthcare system. The volume and stability of the data make it valuable for evaluating clinical outcomes over time and for reaching rare disease patient populations. The design of taXonomy paired with HealthVerity’s commitment to transparent supplier relationships marks it as an industry-leading, research-oriented claims dataset.”
– Taylor Schwartz, Principal, Evidence and Strategy, Avalere
Status quo
Most organizations rely on fragmented open and closed claims products, separate vendor relationships, inconsistent patient matching and coverage gaps that no single vendor can fulfill.
taXOnomy approach
taXOnomy integrates the industry’s deepest open-claims coverage with HealthVerity’s curated closed claims and lab data from the top 2 sources — all deduplicated, linked and delivered as one HIPAA-certified dataset.
Deepest open-claims coverage in the industry
Unsurpassed longitudinality across the full payer landscape
Access to data insights previously unavailable from fragmented open-only or closed-only approaches
Status quo
2-3 big aggregators with broadly the same open claims data from the same sources.
taXOnomy approach
In addition to the widely available open claims data we overlay the largest set of closed claims data ever assembled, and lab data from the top 2 largest labs sources that are not available anywhere else in combination.
Unsurpassed longitudinality
Highest data fidelity available
Data insights that are not possible with the status quo
Largest patient and physician universe
Access 400M+ patient journeys spanning the full payer landscape, with open and closed claims integrated in a single view. With coverage representing roughly 9 in 10 insured Americans for prescriptions and 7 in 10 for medical encounters, taXOnomy consistently uncovers 25% to 65% more patients from the medical benefit than legacy solutions.
Deduplicated by default
One clean record instead of every transaction from every supplier, so each analysis starts from a single, reliable view — deduplicated by default, not as an extra step customers have to run themselves.
Seamless data exchange and activation
Seamlessly integrate taXOnomy with HIPAA-certified data from the nation’s largest healthcare and consumer data ecosystem, or link your proprietary data for an even more robust view. Updated monthly across 4M+ NPIs and continuously expanding payer coverage, taXOnomy connects natively to HealthVerity Marketplace, eXOs and Audiences — so insights reach activation without switching tools.
The right view for your use case
